functions. For each function, the number represents the accumulated sample collected in the function body and all its child calls. The second list does not count the samples collected in the child call. This summary page shows that the Visual Studio parser collected 30.71% samples during the execution of the Drawmandel method. The remaining 69% of the samples ar

At the time of graduation, I encountered the problem of uneven distribution of samples in various categories--a very large number of samples in some categories, and a very small number of samples in some categories, which is the so-called class imbalance (class-imbalance) problem.What is a class imbalance problemClass imbalance (class-imbalance) refers to the une

that the level of C ++ for foreigners is really high. Here, class inheritance is basically brought to the extreme. The ability to analyze such code is simply a pleasure. First, let's take a look at the basic class kerberosamplepipe, which is defined as follows: Class program osamplepipe { Public: // Virtual default destructor Virtual ~ Export osamplepipe (){} /// Returns a pointer to the beginning of the output samples. /// This function is provide

for sample training. This means that many people can only use the trained classifier provided by opencv for pedestrian detection. However, the built-in classifier of opencv uses navneetThe samples provided by Dalal and Bill triggs are not necessarily suitable for your application. Therefore, for your specific application scenarios, it is necessary to re-train your classifier. The purpose of this article is here. Re-train the pedestrian detection proc

Introduction to LDA algorithmA. LDA Algorithm Overview:Linear discriminant Analysis (Linear discriminant, LDA), also called Fisher Linear discriminant (Fisher Linear discriminant, FLD), is a classical algorithm for pattern recognition, It was introduced in the field of pattern recognition and artificial intelligence in 1996 by Belhumeur. The basic idea of sexual discriminant analysis is to project the high-dimensional pattern samples to the optimal d

)))This becomes the min (J (w))The process of updating W isW:=w?α?▽j (w) w:=w?α?1n? N∑i=1 (HW (xi) yi)? xi)where α is the step length, until J (w) can no longer stopThe biggest problem with the gradient descent method is that it will fall into the local optimum, and each time the cost of the current sample is calculated, it is necessary to traverse all the samples in order to get the costing value, so the calculation speed will be much slower (althoug

The principle of isolation Forest algorithm introduced in this article is described in my blog: Isolation Forest anomaly detection algorithm principle, we only introduce the detailed code implementation process in this article.1, the design and implementation of ItreeFirst, we refer to the construction pseudocode of Itree in the original paper:Write a picture description here1.1 Designing the data structures of the Itree classItree is a binary tree based on the original paper and the pseudo-code

number of samples is large, the iterative speed of the method can be imagined.Advantages: Global optimal solution, easy parallel implementation;Cons: The training process is slow when the number of samples is large.From the number of iterations, the number of BGD iterations is relatively small. The convergence curve diagram of its iteration can be expressed as follows:2, small batch gradient descent method

This article describes how to use the kNN algorithm using Python code examples. Here is an example to predict the gender of Douban movie users. If you need a friend, refer to the adjacent algorithm, or K-Nearest Neighbor (kNN, k-NearestNeighbor) classification algorithm is one of the simplest methods in Data Mining classification technology. The so-called K-Nearest Neighbor refers to k nearest neighbors, which means that each sample can be represented by k nearest neighbors. The core idea of kNN
