Introduction to data set
After learning the theory of deep learning, we should start code practice, which is basically divided into data reading, data preprocessing (enhancement), model construction and training
First, let's introduce the data set. The data set used this time is CIFAR10, which is a classic 10 classification color picture ...

1, Overview
Here, we will explore the construction of circular neural network (RNN) for music generation. We will train a model to learn the pattern in the original score of [ABC notation], and then use the model to generate new music.
1. On ABC notation
For an overview of ABC notation, you can check the following website.
What is ABC notat ...

Machine learning series - SVD
SVD is Singular value decomposition.
An important decomposition form in linear algebra. The special meaning of its matrix can be used to deal with linear correlation. For example, in natural language processing, SVD method can be used for news classification, and good results have been achieved. The specific proc ...

Boltzmann Boltzmann machine
Based on the idea of simulated annealing, Hinton and Ackley introduced random mechanism into Hopfield model and proposed Boltzmann machine.
Like Hopfield model, the idea of Boltzmann machine is also the idea of energy. Hopfield model is a definite mechanism when calculating the state transition. Boltzmann machine i ...
