- 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).Find the total number Q of tunable parameters in a general L-hidden-layer neural network, in terms of variables expressed in the layer sizes below 1 layer_sizes= [N, U_1, ., U_L, C] (b) Based on your answer in part (a), explain how the input dimension N and number of data points P each contributes to Q. How is this different from kernel methodsThe learning problem is to find the unknown (functional) relationship hy between objects x X and targets y y based solely on a sample z = (x, y) = ((x1, Y1), ..., (xms Ym)) = (X × y)m of size meN drawn iid from an unknown distribution Pxy. If the output space Y contains a finite number Y of elements then the task is called a classification learning problem.

- I need to implement a python code for Q learning and SARSA method. My example involves a cliff walking experiment where the rewards are -1 except for the region marked as cliff if the agent steps there the reward is -100 and the agent is sent back to the start. The values used are alpha = 0.1, y or gamma = 1 and the e- greedy action is 0.1. After using these values on both algorithm the results needs to be shown by using matplot. The graph should have episodes in the x axis and sum of rewards during episode on the y axis. It needs to be smoothed out by averaging over 10 runs and, plotting moving average over last 10 episodes. This needs to be done in python using numpy and panda but I'm not allowed to use gym library or any other library.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 .Consider eight points on the Cartesian two-dimensional x-y plane. a g C For each pair of vertices u and v, the weight of edge uv is the Euclidean (Pythagorean) distance between those two points. For example, dist(a, h) : V4? + 1? = /17 and dist(a, b) = v2? + 0² = 2. Because many pairs of points have identical distances (e.g. dist(h, c) V5), the above diagram has more than one minimum-weight spanning tree. dist(h, b) = dist(h, f) Determine the total number of minimum-weight spanning trees that exist in the above diagram. Clearly justify your answer.
- Suppose we are fitting a neural network with three hidden layers to a training set. It is found that the cross validation error Jcv(0) is much larger than the training error Jtrain (0). Should we increase the number of hidden layers?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; };…Consider the following perceptron with the activation function f(I)=arctan(I-0.6).
