Convolution and Pooling of TensorFlow Basic Operations

As mentioned earlier Operation and Significance of Image Convolution And some examples are implemented with filter2D function in OpenCV. The filter 2D function in OpenCV only uses a convolution core to deconvolute a single image matrix. In TensorFlow, the convolution operation is mainly used in the convolution layer of CNN, so the input is no ...

Java Code Optimization Points

Principle of optimization Code optimization refers to the equivalent transformation of program code (i.e. the result of running a program without changing it). Program code can be either intermediate code or object code. Equivalence means that the result of code running after transformation is the same as that of code running before transfo ...

Use LSTM for a small classification problem

Take a simple example to see how LSTM does classification in tensorflow. This is a particularly simple example of how LSTM works by counting 1 of a 20-length binary string to something you can do with a for. You can stop here and see what you think. import numpy as np from random import shuffle input has a total of 2^20 combinations, so m ...
