Self-study machine learning three months, exposure to a variety of algorithms, but many know its why, so want to learn from the past to do a summary, the series of articles will not have too much algorithm derivation.We know that the earlier

The basic structure of alexnetAlexnet is composed of 5 convolutional layers and three fully connected layers, a total of 8 weight layers (the pooling layer is not a weight layer because it has no parameters), wherein the RELU activation function on

Original: ImageNet classification with deep convolutionalneural NetworksI. Limitations of LenetFor a long time, Lenet had achieved the best results in the world at the time, albeit on small-scale issues, such as handwritten numerals, but had not

Fancy explanations for Autoencoder and vae What is an automatic encoderThe Automatic encoder (Autoencoder) is initially used as a compression method for data, which has the following characteristics:1) high correlation with the data, which means

This article content and picture Main reference: Understanding Lstm Networks lstm Core thought Lstm was first proposed by Hochreiter & Schmidhuber in 1997, designed to address long-term dependency problems in neural networks, and to remember that

In recent years, unsupervised learning has become the focus of research, with little left to be picked with supervised learning of low branches of fruit. The models of VAE (variational auto-encoder, variable-encoder) [1,2] and GAN (generative

We can easily get help through the Python interpreter. If you want to know more about an object, you can call Help (object). There are also useful ways in which dir (object) displays most of the associated property names for that object, and Object._

LSTM is the most important is the understanding of the cell, the first to see this classic blog, after reading the feeling of each division have read, but the overall integration is not up, and then saw the great God wrote a summary of the blog, the

Why use sequence models (sequence model)? There are two problems with the standard fully connected neural network (fully connected neural network) processing sequence: 1) The input and output layer lengths of the fully connected neural network are

In recent years, ReLU has become more and more popular in deep learning. Its mathematical expression is simple: f (x) =max (0,x). Obviously, when the input signal 0 the case, the output equals the input. In two-dimensional cases, the effect after
