Last week finished writing the code, but because did not notice the implementation of the Softmax related to the result is not correct, correct results can be corrected, with 200 pictures to iterate 200 times can be more than 90% of the correct rate,

Before the game 2048 fire, just in other languages to write a, now learning python, just think up, then decided to write a 2048 with Python, because did not learn the interface programming in Python, so wrote an extremely simple interface 2048. Game

Use python to implement an unbounded 2048, python interface 2048 In the past, when the game was on fire for 2048, I was writing one program in other languages. Now I learned python and decided to use python to write a 2048 program. Since I have

Today we bring the solution of EM derivation for mixed Gaussian model.All codes are as follows!def Ndimensiongaussian (X_vector,u_mean,covariancematrix): #X =numpy.mat (x_vector) x=x_vector D=numpy.shape (X) [0] #U =numpy.mat (U_mean) U=u_mean #CM

Write an unbounded 2048 game in Python, python2048 In the past, when the game was on fire for 2048, I was writing one program in other languages. Now I learned python and decided to use python to write a 2048 program. Since I have never learned

Although the neural network has a very complete and useful framework, and BP Neural network is a relatively simple and inefficient one, but for the purpose of learning to achieve this neural network is still meaningful, I think. The following

This article mainly describes how to use Python to write an unbounded 2048 game. if you need more information, refer to the previous 2048 games, you can write one in other languages, now I want to learn python, just think of it, I decided to use

Python-based three-layer BP neural network algorithm example, pythonbp This example describes the three-layer BP neural network algorithm implemented by Python. We will share this with you for your reference. The details are as follows: This is a

The DES algorithm in Python has been used in recent work, although there are ready-made libraries, but the total feeling is inconvenient. The Des and Mac algorithms previously written in C and Java are then ported to Python. There's no problem with

Title Description:Recently, the project encounters an interesting topic, feeling a lot, forget it. Abstract out, roughly: a total of 100 dumplings on the table, of which there are 10 dumplings covered with coins, asked: How many times the expected
