- The language must be in python. Just do numbers 5-7 Neural Network Units Implement a single sigmoid neural network unit with weights of [-1.2, -1.1, 3.3, -2.1] Calculate the outputs for two training examples:Example 1: [0.9, 10.0, 3.1, 1]Example 2: [0.9, 2.1, 3.7, 1] Note that you don't have to explicitly include a threshold or bias since the examples include a last element of 1 which means that the last weight effectively operates as a threshold. Assuming that a sigmoid unit response >0.5 denotes a positive class and <0.5 is negative class, is example 1 positive or negative? is example 2 positive or negative? Create a single ReLU unit and provide the outputs for those examples. Calculate the derivative of the sigmoid with respect to net input for both examples Calculate the derivative of the ReLU with respect to net input for both examplesWrite a python program that create an automaton simulator that shows deterministic finite automata and non-deterministic finite automata.The language for coding must be in python Neural Network Units Implement a single sigmoid neural network unit with weights of [-1.2, -1.1, 3.3, -2.1] Calculate the outputs for two training examples:Example 1: [0.9, 10.0, 3.1, 1]Example 2: [0.9, 2.1, 3.7, 1] Note that you don't have to explicitly include a threshold or bias since the examples include a last element of 1 which means that the last weight effectively operates as a threshold.

- In programming, we use the mask concept to indicate information that can be shown to the user and information that must be “masked”, that is, hidden. In an implementation of a hangman game, we use a mask to indicate which secret word positions the player has already guessed right (whose the contents must therefore be shown to the player), and which positions must remain hidden. Each time that the player hits a letter of the hidden word, the mask is updated so that it has little dashes in the places of letters that the player has not hit yet and show it, in their proper place, the letters that he already hit it. For example, if the word is "cards", the current mask is: - a - - s and the player guesses the letter "d", the mask should be updated to: - a - ds.Write a function called update_mask that takes as input a string containing the word secret (in the example above, this word would be “cards”), a list whose elements are the characters of the current mask (in the example above…Question5: Write a python program to train neural network to classify two clusters in a 2-dimensional space for implementing XOR, where the weight is -0.50 and x>-0.5. Also name the class by your nameWrite a program in C++ to simulate a 1-dimension random walk along a circular tiled path. At each step, the walker randomly selects, with equal probability, to move to the left or right. The program displays the walker’s progress as it moves from tile to tile. The simulation ends as soon as the walker visits each tile at least once. The program displays the number of times the walker visited each tile. The program displays the number of times the walker moves.
- only java program, a word search puzzle, where one is presented with a grid of letters and needs to find a word by choosing adjacent letters, is the Knight-move word search puzzle, where you’re presented with a grid of letters and need to find a word in a configuration where adjacent letters in the word are reachable by moving like a knight in chess. A knight in chess moves from its current spot by either two rows and one column, or two columns and one row, in any direction. So, the knight at position "K" in the table below, can move to any of the spaces labeled "X" Write a java program that tries to find a word in a grid of letters where each letter is connected to the next by a knight move. Some specific puzzle rules: •You can never "wrap around" any edge of the grid •You can never use the same letter twice. There will be several input instances from a data file. Each input will begin with values r and c (both ≤ 8), denoting the dimensions of the grid. Values of r or c of 0 signify…Write a python program that implements the estimation of Pi through a Monte Calo simulation.a.
