Excellent solutions have been demonstrated mostly in image processing applications which involve large, continuous output spaces. Now for the moment of truth…let's see how it performs on our example face. Last edited February 26, 2017. The above formulation has the advantage of being easy to use and using fewer resources in terms of space requirements and making a lot more logical sense. Decision Matrix Analysis works by getting you to list your options as rows on a table, and the factors you need consider as columns. | Site Design by GripMedia. If a simple GAN is used for this problem then, Jan-Yan Zhu and his colleagues (2017) suggested: "With large enough capacity, a network can map the same set of input images to any random permutation of images in the target domain, where any of the learned mappings can induce an output distribution that matches the target distribution. We propose a new equilibrium enforcing method paired with a loss derived from the Wasserstein distance for training auto-encoder based Generative Adversarial Networks. Basic charts are not enough to manage a project. As of their success on supervised tasks, SGD based algorithms have been adopted for GAN training as well.

In my previous post about generative adversarial networks, I went over a simple method to training a network that could generate realistic-looking images. Learn what Generative Adversarial Networks are without going into the details of the math and code a simple GAN that can create digits! In this tutorial, you will learn what Generative Adversarial Networks (GANs) are without going into the details of the math. GANs are neural networks that generate synthetic data given certain input data. An example of such a class of algorithms are the generative adversarial networks (GANs, Goodfellow et al. This is a simple example to illustrate the basic idea behind Generatives Adversarial Networks (GANs). A more detailed example has been created by Diego Gomez Mosquera , using PyTorch as well as SensorFlow. That is very few examples to learn from, for a classification problem that is far from simple. Questions: The first three questions this week are here to make sure that you understand some of the most important points in the GAN paper. Excellent solutions have been demonstrated mostly in image processing applications which involve large, continuous output spaces. If you wanted to create an AI that imitates an art style, like Picasso's for example, you could feed a GAN a bunch of his paintings. GitHub Gist: instantly share code, notes, and snippets. The Excel Gantt chart template breaks down a project by phase and task, noting who’s responsible, task start and end date, and percent completed.

Using image sprites will reduce the number of server requests and save bandwidth. Specifically, we will slowly build upon the ideas and the principles that led to the evolution of generative adversarial networks (GAN). Typical Machine Learning workflow. I then tuned the third-harmonic load condition to “square” the intrinsic voltage waveform, producing the Class F–shaped waveforms shown. From a high level, GANs are composed of two components, a generator and a discriminator. As of PHP 5. Inthe previous section, (comparingoptimality and game theory), we learned that competition was an importantfeature of game theory. Excellent solutions have been demonstrated mostly in image processing applications which involve large, continuous output spaces. GANs in Action teaches you how to build and train your own Generative Adversarial Networks, one of the most important innovations in deep learning. Basic charts are not enough to manage a project. Conditional Generative Adversarial Nets in TensorFlow. I also think the theory in the paper scared off a lot of people, which is a bit of a shame. The GaN transistor structure is a purely lateral device, without the parasitic bipolar junction common to silcon MOSFETs. As a result, our models set a new level of performance among ImageNet GAN models, improving on the state of the art by a large margin.

Therefore, through GAN learning the relationship between the two data distributions of adversarial examples and clean samples, the study focuses on different issues ranging from the generation of single adversarial example to data distribution of adversarial example, providing a new research direction for further efficient generation of better. Good articles are articles that many people find to be better than other articles. Don't panic. I have 8 input features and 1 target (which is continuous valued label). As of their success on supervised tasks, SGD based algorithms have been adopted for GAN training. If you have a dimmer switch, the dimmer is in series with the bulb - kinda like a variable resistor - and reduces the voltage/current/brig. With these values we can now use the following formulas to plot the relationship between fastener torque and the pressure exerted on the devices in this example. the objective is to find the Nash Equilibrium. Caribou were counted in strip transects that were 1‐mile wide. Results and discussion The first sample contained a thin InN or. Introduction to generative adversarial network. It could be to assess an individual’s performance in speaking or presenting or it is a way for companies to evaluate their products and services. Namely, we first divide the spectrograms into multiple frequency bands with overlap, reconstruct the individual bands using the GAN-based postfilter trained for each band, and finally connect the bands with overlap. A SIMPLE MODEL OF OPTIMAL HATE CRIME LEGISLATION LI GAN, ROBERTON C. two-sample test is directly linked to its generalization error, which has a sample complexity upper-upper bounded as O(n 1=2). Understanding the Python code. NET Framework 4. Ham and Pineapple Pita Pizzas. Therefore, the enhancement GaN reverse bias or "diode" operation has a different mechanism, but a similar function. “Simply, people can no longer remember passwords good enough to reliably defend against dictionary attacks, and are much more secure if they choose a password too complicated to remember and then write it down. Image Sprites - Simple Example. A simple random sample of 15 transects (n) were chosen from the 286 transects potentially available (N). # set each sample mean to 0 featurewise_std_normalization=False, # divide inputs by std of the dataset samplewise_std_normalization=False, # divide each input by its std zca_whitening=False, # apply ZCA whitening zca_epsilon=1e-06, # epsilon for ZCA whitening rotation_range=0, # randomly rotate. Learning PyTorch with Examples This sounds complicated, it's pretty simple to use in practice. in, input_file3. The low-resolution images obviously don't contain enough information to actually reconstruct the original image. In previous post, we have already seen basic terms, formulas in cpu scheduling and First Come First Serve Scheduling Algorithm. That is very few examples to learn from, for a classification problem that is far from simple. The following are code examples for showing how to use keras. So this is a challenging machine learning problem, but it is also a realistic one: in a lot of real-world use cases, even small-scale data collection can be extremely expensive or sometimes near-impossible (e. With the outbreak of Coronavirus (Covid-19) now affecting several educational institutions around the world, we at 2Simple are offering free access to both Purple Mash and Serial Mash for schools and home users. Specifically, we will slowly build upon the ideas and the principles that led to the evolution of generative adversarial networks (GAN). (see also section 8. The constructor of the GAN class is pretty simple and in an essence, it delegates construction of the Generative Model and the Discriminative Model to specialized functions. LEDs are used as indicator lamps in many devices and are increasingly used for other lighting. Ideas based on current affairs. The Tutorials/ and Examples/ folders contain a variety of example configurations for CNTK networks using the Python API, C# and BrainScript. When we refer to hazards in relation to occupational safety and health the most commonly used definition is ‘ A Hazard is a potential source of harm or adverse health effect on a person or persons’.

Simply rephrasing a live question (changing the name and the figures) doesn't change its essence. GMATPrep questions are fine, as are OG questions. GMATFocus and live questions are not. Test prep materials do not (should not) have rephrasings of live questions, and gmatclub will not tolerate such rephrasings.

If by rephrasing you mean finding another problem that deals with the same concept, that's different than just putting in different words that mean the same thing. If I get a comb/perm question on a live GMAT that is tough and I want to ask about it, I'm going to go through the OG and find a similar question and ask that question as it is written in the OG, and I won't tell anyone that the source of my curiosity is from a live question. That would be acceptable. I wonder if we should implement a policy for mods on here that if a question is not posted along with the source, or the source is not identified in a post by the Original Poster within a set time, that question gets deleted by the first mod to notice the time has lapsed. Just a thought on how to keep GMAT "clean".

what about PS problems that ask to solve a decimal fraction or results of adding a bunch of fractions together.

for example: what does .1 + .2 + .3 equal to?
the question can't get more generic than that. would that be a violation since the fractions can be easily substitute with other numbers while keeping the same "format"?

#### MS Thesis defence

##### Venue: Microsoft Teams (online)

In this thesis we will discuss the properties of the category $\mathcal{O}$ of left $\mathfrak{g}$-modules having some specific properties, where $\mathfrak{g}$ is a complex semisimple Lie algebra. We will also discuss the projective objects of $\mathcal{O}$, and will establish the fact that each object in $\mathcal{O}$ is a factor object of a projective object. We will prove that there exists a one-to-one correspondence between the indecomposable projective objects and simple objects of $\mathcal{O}$. We will discuss some facts about the full subcategory $\mathcal{O}_\theta$ of $\mathcal{O}$. And finally we will establish a relation between the Cartan matrix and the decomposition matrix with the help of the BGG reciprocity and the fact that each projective module in $\mathcal{O}$ admits a $p$-filtration.

## 英国补考|抽样调查作业代写sampling theory of survey代考|ADMISSIBLE ESTIMATORS

We have seen in Section $2.5$ that in almost all practical situations, the UMVUE for a finite population total does not exist. The criterion of admissibility is used to guard against the selection of a bad estimator.
An estimator $T$ is said to be admissible in the class $C$ of estimators for a given sampling design $p$ if there does not exist any other estimator in the class $C$ better than $T$. In other words, there does not exist an alternative estimator $T^{}(\neq T) \in C$, for which following inequalities hold. (i) $V_{p}\left(T^{}\right) \leq V_{p}(T) \quad \forall T^{}(\neq T) \in C$ and $\mathbf{y} \in R^{N}$ and (ii) $V_{p}\left(T^{}\right){h t}$ based on a sampling design $p$ with $\pi{i}>0 \forall i=1, \ldots, N$ is admissible for estimating the population total $Y$.
Proof
The proof is immediate from Theorem 2.5.2. Since $\widehat{Y}{h t}$ is the UMVUE when $\mathbf{y} \in R{0}$, we cannot find an estimator $\forall T^{*}\left(\neq \widehat{Y}{h t}\right) \in C{l l t}$ for which (2.6.1) holds.

The Theorem 2.6.1 of admissibility of the HTE $\widehat{Y}{h t}$ in the class $C{h h}$ was proved by Godambe (1960). Godambe and Joshi (1965) proved the admissibility of $\widehat{Y}{h t}$ in the class of all unbiased estimators $C{t}$, and it is given in Theorem 2.6.2.
Theorem 2.6.2
For a given sampling design $p$ with $\pi_{i}>0 \forall i=1, \ldots, N$, the HTE $\widehat{Y}{h t}$ is admissible in the class $C{u}$ of all unbiased estimator for estimating the total $Y$.

An estimator $e(s, \mathbf{y})$ is said to be inadmissible in a class of estimators $C$ if there exists an estimator $e^{*}(s, \gamma)(\in C)$ better than $e(s, \gamma)$. Hence it is natural to question how an inadmissible estimator could be improved. The method of improvement of an inadmissible estimator with the aid of sufficient statistics is known as Rao-Blackwellization. The concept of sufficient statistics in survey sampling was introduced by Basu $(1958)$, while the concepts of linear sufficiency, distribution-free sufficient statistics, and Bayesian sufficiency were also introduced by Godambe (1966, 1968). Details have been given by Cassel et al. (1977), Chaudhuri and Stenger (1992), and Thompson and Seber (1996).

Let $s=\left(i_{1}, \ldots, i_{k}, \ldots, i_{n_{s}}\right)$ be an ordered sample of size $n_{s}$ selected from a population $U$ with probability $p(s)$ using a sampling design $p$, where the unit $i_{k}$ is selected at the $k$ th draw. After selection of sample $s$, the responses $\gamma_{i_{1}}, \ldots, \gamma_{i_{n_{s}}}$ were obtained from sampled units $i_{1}, \ldots, i_{n_{s}}$, respectively. The ordered data based on the ordered sample $s$ are denoted by $d=\left{\left(i_{1}, \gamma_{i_{1}}\right), \ldots,\left(i_{k}, \gamma_{i_{n s}}\right)\right}=\left(i_{k}, \gamma_{i_{k}} ; i_{k} \in s\right)$.

Let $\tilde{s}=\left(j_{1}, j_{2}, \ldots, j_{v_{s}}\right)$ with $j_{1}<j_{2}<\ldots<j_{v_{s}}$ be the unordered sample obtained from $s$ by taking distinct units of $s$ and arranging them in ascending order of their labels. Let us denote the operator $r$, which transforms the ordered sample $s$ to the unordered sample $\widetilde{s}$, i.e., $r(s)=\widetilde{s}$. The unordered data are denoted by $\tilde{d}=\left{\left(j_{1}, \gamma_{j_{1}}\right), \ldots,\left(j_{v_{s}}, \gamma_{j_{v_{s}}}\right)\right}=\left(j, \gamma_{j} ; j \in \widetilde{s}\right)$. We define the operator $R$ to get unordered data $\tilde{d}$ from ordered data $d$, i.e., $R(d)=\tilde{d}$
Example $2.7 .1$
Let $U=(1,2,3,4,5), \quad \mathbf{y}=(10,15,15,20,10), \quad$ and $\quad s=(5,2,5)$. Here $y_{1}=10, \quad y_{2}=15, \quad y_{3}=15, \quad y_{4}=20, \quad$ and $\quad \gamma_{5}=10 ; \quad r(s)=\widetilde{s}=(2,5)$, $d={(5,10),(2,15),(5,10)}$ and $R(d)=\widetilde{d}={(2,15),(5,10)}$.

### Indicator Constraints v. Big M

Way, way back I did a couple of posts related to how to model "logical indicators" (true/false values that control enforcement of constraints):

• #### Indicator Implies Relation

The topic ties in to the general issue of "big M" model formulations. Somewhere around version 10, CPLEX introduced what they call indicator constraints, which are essentially implications of the form "if constraint 1 holds, then constraint 2 holds". As an example, if $a$ and $b$ are vector respectively scalar parameters, $x$ is a binary variable and $y$ is a vector of real variables, you might use an indicator constraint to express $x=1 \implies a'y\le b$.

That same constraint, in a "big M" formulation, would look like $a'y \le b + M(1-x)$. Using an indicator constraint saves you having to make a careful choice of the value of $M$ and avoids certain numerical complications. So should you always use indicator constraints? It's not that simple. Although "big M" formulations are notorious for having weak relaxations, indicator constraints can also result in weak (possibly weaker) relaxations.

For more details, I'll refer you to a question on the new Operations Research Stack Exchange site, and in particular to an answer containing information provided by Dr. Ed Klotz of IBM. My take is that this remains one of those "try it and see" kinds of questions.

Recursive Neural Networks (RvNNs) are deep neural networks used for natural language processing. We get a Recursive Neural Network when the same weights are applied recursively on a structured input to obtain a structured prediction. Business leaders and technology professionals need to understand what is Recursive Neural Network, what it can do, and how it works.

#### PCP in AI and Machine Learning

In Partnership with Purdue University

## What Is a Recursive Neural Network?

Deep Learning is a subfield of machine learning and artificial intelligence (AI) that attempts to imitate how the human brain processes data and gains certain knowledge. Neural Networks form the backbone of Deep Learning. These are loosely modeled after the human brain and designed to accurately recognize underlying patterns in a data set. If you want to predict the unpredictable, Deep Learning is the solution.

Recursive Neural Networks (RvNNs) are a class of deep neural networks that can learn detailed and structured information. With RvNN, you can get a structured prediction by recursively applying the same set of weights on structured inputs. The word recursive indicates that the neural network is applied to its output.

Due to their deep tree-like structure, Recursive Neural Networks can handle hierarchical data. The tree structure means combining child nodes and producing parent nodes. Each child-parent bond has a weight matrix, and similar children have the same weights. The number of children for every node in the tree is fixed to enable it to perform recursive operations and use the same weights. RvNNs are used when there's a need to parse an entire sentence.

To calculate the parent node's representation, we add the products of the weight matrices (W_i) and the children's representations (C_i) and apply the transformation f:

$h = f \left( \sum_{i=1}^{i=c} W_i C_i \right)$, where c is the number of children.

## Recurrent Neural Network vs. Recursive Neural Networks

• Recurrent Neural Networks (RNNs) are another well-known class of neural networks used for processing sequential data. They are closely related to the Recursive Neural Network.
• Recurrent Neural Networks represent temporal sequences, which they find application in Natural language Processing (NLP) since language-related data like sentences and paragraphs are sequential in nature. Recurrent networks are usually chain structures. The weights are shared across the chain length, keeping the dimensionality constant.
• On the other hand, Recursive Neural Networks operate on hierarchical data models due to their tree structure. There are a fixed number of children for each node in the tree so that it can execute recursive operations and use the same weights for each step. Child representations are combined into parent representations.
• The efficiency of a recursive network is higher than a feed-forward network.
• Recurrent Networks are recurrent over time, meaning recursive networks are just a generalization of the recurrent network.

## Recursive Neural Network Implementation

A Recursive Neural Network is used for sentiment analysis in natural language sentences. It is one of the most important tasks of Natural language Processing (NLP), which identifies the writing tone and sentiments of the writer in a particular sentence. If a writer expresses any sentiment, basic labels about the writing tone are recognized. We want to identify the smaller components like nouns or verb phrases and order them in a syntactic hierarchy. For example, it identifies whether the sentence showcases a constructive form of writing or negative word choices.

A variable called 'score' is calculated at each traversal of nodes, telling us which pair of phrases and words we must combine to form the perfect syntactic tree for a given sentence.

Let us consider the representation of the phrase -- "a lot of fun" in the following sentence.

Programming is a lot of fun.

An RNN representation of this phrase would not be suitable because it considers only sequential relations. Each state varies with the preceding words' representation. So, a subsequence that doesn't occur at the beginning of the sentence can't be represented. With RNN, when processing the word 'fun,' the hidden state will represent the whole sentence.

However, with a Recursive Neural Network (RvNN), the hierarchical architecture can store the representation of the exact phrase. It lies in the hidden state of the node R_{a\ lot\ of\ fun}. Thus, Syntactic parsing is completely implemented with the help of Recursive Neural Networks.

## Benefits of RvNNs for Natural Language Processing

• The two significant advantages of Recursive Neural Networks for Natural Language Processing are their structure and reduction in network depth.
• As already explained, the tree structure of Recursive Neural Networks can manage hierarchical data like in parsing problems.
• Another benefit of RvNN is that the trees can have a logarithmic height. When there are O(n) input words, a Recursive Neural Network can represent a binary tree with height O(log\ n). This lessens the distance between the first and last input elements. Hence, the long-term dependency turns shorter and easier to grab.

## Disadvantages of RvNNs for Natural Language Processing

• The main disadvantage of recursive neural networks can be the tree structure. Using the tree structure indicates introducing a unique inductive bias to our model. The bias corresponds to the assumption that the data follow a tree hierarchy structure. But that is not the truth. Thus, the network may not be able to learn the existing patterns.
• Another disadvantage of the Recursive Neural Network is that sentence parsing can be slow and ambiguous. Interestingly, there can be many parse trees for a single sentence.
• Also, it is more time-consuming and labor-intensive to label the training data for recursive neural networks than to construct recurrent neural networks. Manually parsing a sentence into short components is more time-consuming and tedious than assigning a label to a sentence.

### 1. Is CNN recursive?

New models of CNN (Convolutional Neural Networks) feature fully recursive convolutional layers for a fast and accurate image. This approach is quick and does not require extra input channels like surface normal.

### 2. What is the difference between CNN and RNN?

Both CNN (Convolutional Neural Networks) and RNN (Recurrent Neural Networks) form the basis for several AI applications that drive business value. CNN is commonly applied to analyzing visual images. RNN, on the other hand, is a network where connected nodes form a directed graph along a temporal sequence.

CNN has a different architecture from RNN. It uses fee-forward neural networks that use filters and pooling layers, while RNNs have built-in memory similar to a loop and an RNN feed returns to the network. CNNs are generally used to solve spatial data and image recognition problems, while RNNs are more apt to analyze temporal, sequential data like language, texts, or videos.

### 3. Is RNN more powerful than CNN?

CNN is more powerful and faster and includes fewer feature compatibility than RNN. While CNN takes fixed-size inputs and gives fixed-size outputs, RNN can tackle arbitrary input/output lengths.

### 4. How many types of neural networks are there?

There are three critical types of Neural Networks in Deep Learning:

• Artificial Neural Networks (ANN)
• Convolutional Neural Networks (CNN)
• Recurrent Neural Networks (RNN)

# Easy Pronunciation CodeChef Solution

### We Are Discuss About CODECHEF SOLUTION

Easy Pronunciation CodeChef Solution

## Easy Pronunciation CodeChef Solution

Words that contain many consecutive consonants, like “schtschurowskia“, are generally considered somewhat hard to pronounce.

We say that a word is hard to pronounce if it contains 44 or more consonants in a row; otherwise it is easy to pronounce. For example, “apple” and “polish” are easy to pronounce, but “schtschurowskia” is hard to pronounce.

You are given a string SS consisting of NN lowercase Latin characters. Determine whether it is easy to pronounce or not based on the rule above — print YES if it is easy to pronounce and NO otherwise.

For the purposes of this problem, the vowels are the characters {a,e,i,o,u}{a,e,i,o,u} and the consonants are the other 2121 characters.

### Input Format

• The first line of input will contain a single integer TT, denoting the number of test cases.
• Each test case consists of two lines of input.
• The first line of each test case contains a single integer NN, the length of string SS.
• The second line of each test case contains the string SS.

### Output Format

For each test case, output on a new line the answer — YES if SS is easy to pronounce, and NO otherwise.

Each character of the output may be printed in either uppercase or lowercase. For example, the strings YESyeSyes, and YeS will all be treated as identical.

## Easy Pronunciation CodeChef Solution

### Constraints

• 1T1001≤T≤100
• 1N1001≤N≤100
• SS contains only lowercase Latin characters, i.e, the characters {a,b,c,,z}{a,b,c,…,z}

### Sample Input 1

## Easy Pronunciation CodeChef Solution

Test case 11: “appleapple” doesn’t have 44 or move consecutive consonants, which makes it easy to pronounce.

Test case 22: “\textcolor{red}{schtsch}urowskia\textcolor{red}{schtsch}urowskia” has 77 consecutive consonants, which makes it hard to pronounce.

Test case 33: polishpolish doesn’t contain 44 or more consecutive consonants, so it’s easy to pronounce.

Test case 44: \textcolor{red}{tryst}\textcolor{red}{tryst} contains 55 consecutive consonants, making it hard to pronounce.

Test case 55: crycry doesn’t contain any vowels, but its length is less than 44 so it’s still easy to pronounce.

# A first order ODE

1. Sep 22, 2005

I need to solve the following for f(s):

(s^2 + 1)f '(s) + s f(s) = 0

First I isolated for f '(s), which gave me:

f '(s) = -s f(s)/(s^2 + 1)

Then,

d f(s)/ds = -s f(s)/(s^2 + 1)

so, d f(s) = (-s f(s)/(s^2 + 1))ds

Integrating I get:

f(s) = -F(s)ln(s^2 + 1)/2 + C, where F(s) is the antiderivative of f(s) and C is a constant of integration.

Did I do any of that correctly??!!??

2. Sep 22, 2005

### saltydog

Not the last part. Just write it this way:

$$f^{'}+\frac{s}{s^2+1}f=0$$

That's in standard form right? Now calculate the integrating factor $\sigma$, multiply both sides by it, end up with an exact differential on the LHS, integrate, don't forget the constant of integration, that should do it. This is the integrating factor:

$$\sigma=\text{Exp}\left[\int \frac{s}{(s^2+1)}\right]$$

Can you do the rest?

# Eigenvalues of sum of Hermitaion matrices with certain constraints

Let $A$ and $B$ be $n\times n$ Hermitian matrices and $\{\lambda_{A1},\ldots,\lambda_{An}\}$ and $\{\lambda_{B1},\ldots,\lambda_{Bn}\}$ represent their eigenvalues, respectively. If $A+B = \Lambda$ where $\Lambda$ is a diagonal matix with diagonal elements $\{\lambda_1,\ldots,\lambda_n\}$ and $\lambda_{Bn}=0$, can we find $\lambda_{An}$?

• Do you mean that $\lambda_{Bj} = 0$ for $j = 1,\dots,n$, or do you specifically mean that $\lambda_{Bn} = 0$ (and that the other eigenvalues are unknown)? Are these eigenvalues ordered in any particular way? – Omnomnomnom Aug 8 '17 at 21:55
• One or some eigenvalues of $B$ are zero, not all of them. I assume all eigenvalues are non-negative. Thus, $\lambda_{Bn}$ is the smallest eigenvalue. – Bob Aug 8 '17 at 21:58

It follows from the Rayleigh-Ritz theorem (or as an instance of Weyl's inequality) that $$\lambda_{min}(\Lambda) = \lambda_{min}(A + B) \leq \lambda_{min}(A) + \lambda_{min}(B) = \lambda_{min}(A)$$ On the other hand, by another instance of Weyl's inequality, we can get $$\lambda_{min}(\Lambda) = \lambda_{min}(A + B) \geq \lambda_{max}(A) + \lambda_{min}(B) = \lambda_{max}(A)$$ We can't say anything more substantial than that. Both of these inequalities are sharp, and equality is attained with diagonal matrices $A,B$.
