1. Theoretical knowledge Feature points are composed of key points and descriptors. ORB feature points (Oriented FAST and Rotated BRIEF) are composed of Oriented FAST corner points and BRIEF (binary robot independent elemental features) descriptors. Its calculation speed is 100 times that of sift feature points and 10 times that of surf featur ...

Machine learning algorithms usually use cross validation techniques such as kFold to improve the accuracy of the model. In the process of cross validation, the prediction is carried out through the split test set that is not used for model training. These predictions are called out of fold predictions. External prediction plays an important rol ...

1, Save Tensorflow model: 1. Save file description Tensorflow model mainly includes the design (diagram) of the network and the values of trained parameters. Therefore, tensorflow model has two main files: 1) graph.pbtxt: This is actually a text file, which saves the structure information of the model 2) checkpoint file: in fact, it is a tx ...

preface First I did a small project of Gobang, and then I did a more powerful project of Chinese chess, but I never realized a version of "intelligent" AI. It is well known that the bottom layer of ai algorithm for this kind of game problem is to use minimax search algorithm and α-β Pruning pruning optimization, but I ...

Quickly review the soft voting and hard voting in the integration methodThe integration method is to combine the results of two or more separate machine learning algorithms and try to produce more accurate results than any single algorithm.In soft voting, the probability of each category is averaged to produce results. For example, if algorithm ...

Originally, I wanted to make a voice to text, but I found that many blogs didn't say what I wanted. The reasons are as follows: 1. Because the voice supported by Baidu interface is pcm format, and my own is mp3 format file. 2. Baidu only supports the file format within 60s, and what it wants is a long file, and hopes to cut it into 60s to meet ...

What is numpy A basic library for scientific calculation in Python, which focuses on numerical calculation. It is also the basic library of most Python scientific calculation libraries. It is mostly used to perform numerical operations on large and multi-dimensional arrays Axis In numpy, it can be understood as direction, which is expres ...
