## Introduction to neural network quantization -- quantitative perception training

This article begins with the official account of "AI little boy".
Last article This paper introduces the basic process of post training quantization, and demonstrates the simplest post training quantization algorithm with pytorch.
Although post training quantization is easy to operate, most reasoning frameworks provide such off-line ...

## Briefly introduce the use of distributed training DDP in pytorch (combined with examples, quick start)

DDP principle
Distributed data parallel (DDP) supports multi machine and multi card distributed training. pytorch native support. This paper briefly summarizes the use of DDP and the test under multi card, and introduces it according to the actual code.

## [Python + + opencv + Python] license plate extraction, segmentation and recognition

If you want to complete the project, I will put the github link at the end of the article: You can see that the final identification license plate number is min G99999.
In fact, I accidentally thought of doing a small project with c + + in the winter of the previous year, and then realized the license plate extraction and segmentation with c+ ...

## PyTorch learning notes - use of data set and data loader

1. Purpose of using data loader in the model
In the previous linear regression model, we use very little data, so we directly put all the data into the model. However, in deep learning, the amount of data is usually very large. With such a large amount of data, it is impossible to carry out forward calculation and back propagation i ...

## pytorch learning notes 5: learning through examples

1. General ¶
The core of PyTorch is to provide two main functions:
n-dimensional tensor, similar to NumPy, but can run on GPU
Automatic differentiation for constructing and training neural networks
We will use the problem of fitting a third-order polynomial to y = sin(x) as a running example. The network will have four paramet ...

## Through the example, you can quickly understand the pad in 10 minutes_ sequence,pack_padded_sequence and pad_packed_sequence

preface
import torch
import torch.nn as nn
from torch.nn.utils.rnn import pad_sequence
from torch.nn.utils.rnn import pack_padded_sequence
from torch.nn.utils.rnn import pad_packed_sequence
Notice utils. Above RNN, have you? These functions are "usually" used for RNN related processing. So you have to understand some standard conc ...

## Feature Engineering - text features

be careful:
1. All the articles in this series are mainly developed by the gradient lifting tree model. The extracted features are mainly to help the gradient lifting tree model mine the information it can't mine. All the features introduced in this paper can be directly added to the model as features, which is slightly different from the stra ...
