Suppose we have a neural net, which we denote as a function F(x; 0), that performs binary logistic regression to classify between images of cats and dogs. The final layer of F is a sigmoid, so that the output is a number between 0 and 1. Cats are given the label 0, and dogs are given the label 1. We use the NLL loss as our loss function: L(F(x; 0), y) = − [y log F(x; 0) + (1 − y) log(1 — F(x; 0))] We have an image x under consideration and wish to modify our predictions about it. Is the following true? If we want our net to predict 'cat' we should try taking a gradient step new = x − ▼xF(x; 0).

Write a program in Scilab that samples f (x )=3e^−x sinx at x=0,1,2,3,4,5 and then, on the same graph, plots nearest-neighbor, linear and spline interpolations of these data using the interp1 function. The interpolation plots should have 200 samples uniformly spaced over 0≤x≤5 .
Homework due Sep 15, 2022 03:59 +04 Exercise 1 In Exercise 1, we will calculate the chance homophily for an arbitrary characteristic. Homophily is the proportion of edges in the network whose constituent nodes share that characteristic. How much homophily do we expect by chance? If characteristics are distributed completely randomly, the probability that two nodes and y share characteristic a is the probability both nodes have characteristica. which is the marginal probability of a squared. The total probability that nodes x and y share their characteristic is therefore the sum of the square of the marginal probabilities of each characteristic in the network. Instructions • Create a function marginal_prob that takes a dictionary chars with personal IDs as keys and characteristics as values; it should return a dictionary with characteristics as keys and their marginal probability (frequency of occurence of a characteristic divided by the sum of frequencies of each characteristic) as…
Consider a Local Search procedure such as Random Hill Climbing which employs the 2-change modification as neighbourhood function and the following instance of the Travelling Salesman Problem: 10 During the execution of the search, the highlighted (in bold) tour is visited. This current tour has a length of (62): [A → C → B → E → D → A] Select ALL correct statements. D a. The 2-change modification neighbourhood for TSP is reversible. O b. None of the statements is correct. O c. The modification, REMOVE ((A, C), (B, E)) and ADD ((A, B), (C, E)), is not a valid 2-change modification. O d. The current tour is a local minimum. O e. REMOVE ((A, D), (B, E)) and ADD ((A, B), (D, E)) is a valid 2-change modification, but not accepted for the next iteration step. O f. The modification, REMOVE ((A, D), (C, B)) and ADD ((C, D), (A, B)), yields in a tour which is accepted for the next iteration step. g.

3. Suppose that we want to know which agents are connected by a walk of length two in a given network. That is, want to know the set of ordered pairs (i, j) such that there exists a walk of length 2 between any i and j. Define n as the number of nodes and m as the number of links. (a) One way to do this is to input the adjacency matrix A, calculate A2, then output all pairs (i, j) for which A(i) > 0. Defining scalar multiplication and addition as "basic operations," up to a constant c, how many "basic operations" are required to calculate A², in terms of n and m? (Hint: First think about how many operations are required to calculate each entry of A²2, then multiply by the number of entries.)

A unigram is a sequence of words of length one (i.e. a single word).• A bigram is a sequence of words of length two.• The conditional probability of an event E2 given another event E1, written p(E2|E1), is the probability that E2 will occur given that event E1 has already occurred.We write p(w(k)|w(k-1)) for the conditional probability of a word w in position k, w(k), given the immediately preceding word, w(k-1). You determine the conditional probabilities by determining unigram counts (the number of times each word appears, written c(w(k)), bigram counts (the number of times each pair of words appears, written c(w(k-1) w(k)), and then dividing each bigram count by the unigram count of the first word in the bigram:p(WORD(k)|WORD(k-1)) = c(WORD(k-1) WORD(k)) / c(WORD(k-1)) Apply and incorporate instrutions to code below. #include <stdio.h>//including headers#include <string.h>#include <stdlib.h> struct node{//structure intialization int data; struct node *next; };…
Why is an RNN (Recurrent Neural Network) used for machine translation, say translating English to French? (Check all that apply.) It can be trained as a supervised learning problem. It is strictly more powerful than a Convolutional Neural Network (CNN). It is applicable when the input/output is a sequence (e.g. a sequence of words).

Logistic regression aims to train the parameters from the training set D = {(x(i),y(i)), i 1,2,...,m, y ¤ {0,1}} so that the hypothesis function h(x) = g(0¹ x) 1 (here g(z) is the logistic or sigmod function g(z) can predict the probability of a 1+ e-z new instance x being labeled as 1. Please derive the following stochastic gradient ascent update rule for a logistic regression problem. 0j = 0j + a(y(¹) — hz(x)))x; ave. =
Suppose that a manufacturing company builds n different types of robots, sayrobots 1, 2, . . . , n. These robots are made from a common set of m types of materials, saymaterials 1, 2, . . . , m. The company has only a limited supply of materials for each year,the amount of materials 1, 2, . . . , m are limited by the numbers b1, b2, . . . , bm, respectively.Building robot i requires an aij amount from material j. For example, building robot 1requires a11 from material 1, a12 from material 2, etc. Suppose the profit made by sellingrobot i is pi.

3. Suppose a deep neural network N is used for the image quality assessment problem. The input of the problem is a pair of images 1₁ and 12. The output is a binary label L. L = 0 means that quality of 1₁ is higher than l₂ and L = 1 means that quality of l2 is higher than 1₁.The network design is as follows: 1₁ and 1₂ are separately passed through a sub-network N₁ (which has a few convolutional and fully connected layers) to get feature vectors f1 and f2. f1 and f2 would be concatenated and passed through another sub-network N₂ which has a few fully connected layers with ReLU activations. This sub-network is where the two images would be processed jointly. Finally, a sigmoid function would be used to predict the binary label L. Given a random image pair (A,B), the network says quality of A is higher than B. Can you guarantee that if you give (B,A) to the network, it will still say that quality of A is higher than B? If your answer is YES: Prove it. If your answer is NO: Explain what is…

Please answer the following question in depth with full detail. Consider the 8-puzzle that we discussed in class. Suppose we define a new heuristic function h3 which is the average of h1 and h2, and another heuristic function h4 which is the sum of h1 and h2. That is, for every state s ∈ S: h3(s) =h1(s) + h2(s) 2 h4(s) =h1(s) + h2(s) where h1 and h2 are defined as “the number of misplaced tiles”, and “the sum of the distances of the tiles from their goal positions”, respectively. Are h3 and h4 admissible? If admissible, compare their dominance with respect to h1 and h2, if not, provide a counterexample, i.e. a puzzle configuration where dominance does not hold.
