preface Tip: Here you can add the general contents to be recorded in this article: For example, with the continuous development of artificial intelligence, machine learning technology is becoming more and more important. Many people have started learning machine learning. This paper introduces the basic content of machine learning. Ti ...

introduce In this experiment, we will use support vector machine (SVM) and understand its working principle on data. The data sets used in this experiment include: ex2data1.mat - linear SVM classification datasetex2data2.mat - Gaussian kernel SVM classification datasetex2data3.mat - cross validation Gaussian kernel SVM classification dat ...

This picture and text is the learning notes of Datawhale team learning pytoch. The main contents include the concept of tensor (0-dimensional, 1-dimensional, 2-dimensional, 3-dimensional, 4-dimensional tensor, etc.), the principle of automatic derivation (understanding through dynamic graph), and the understanding of parallelism. Chapter 0 ...

import numpy as np Create an empty vector of length 10: Z = np.zeros(10) print(Z) How to find the memory size of any array Z = np.zeros((10,10)) print("%d bytes" % (Z.size * Z.itemsize)) Create a vector with a range of 10 to 49 # Z = np.arange(10,50) # print(Z) Invert a vector (the first element becomes the last) # Z = np.arange(50) ...

1, Round Judge the distance from the point to the center of the circle, and then compare the distance with the radius of the circle. Less than is on the inside of the circle, equal to the edge of the re circle, greater than the outside of the re circle. bool CScenes::IsPointInCir(CPoint point)//Point is a point from the outside { int dis,x,y ...

When dealing with classification problems, category imbalance is not only a problem we often encounter, but also a problem that often occurs in actual use scenarios. Category imbalance will bring challenges to the prediction task, and lead to poor prediction effect of a few categories, because the hypothetical scenario of most machine le ...

Machine learning -- logistic regression (multivariate classification) programming training reference material: 1.Mr. Huang haiguang: Wu Enda machine learning notes github This paper is the first part of the third programming training in Wu Enda's machine learning course. Programming tasks: Recognize handwritten digits (0 to 9) using logica ...

Data import and preprocessing The first is to import all packages required for this data mining import pandas as pd import matplotlib.pyplot as plt import numpy as np from sklearn.preprocessing import StandardScaler from sklearn.preprocessing import MinMaxScaler from sklearn.model_selection import train_test_split from sklearn.decompositi ...

1. KNN's Movie Classification For a new movie, how do you tell if it's a love movie or an action movie? You can tell by the number of kisses or fights. Compare this movie with many already tagged movies, calculate the Euclidean distance between them, sort by distance, and find the shortest k (three below)And then see how many of these k are lo ...
