I happened to see the discussion of my partners: I don’t know the specific content, but it seems to be sayingLogin interface verification codeWhat happened. Verification code is a common problem in the testing process, so I can’t help thinking:How to identify and process the verification code efficiently in the process of automated testing, so […]

origin Recently read < < my first algorithm book > > ([Japan] Ishida Baohui; Miyazaki Xiuyi)This series of notes is intended to use golang exercises Kmeans clustering algorithm Clustering is when multiple data are input, The operation of grouping “similar” data into groups. Kmeans algorithm is one of clustering algorithms. Firstly, k points are randomly […]

Kmeans clustering algorithm clustering In unsupervised learning, the labeled information of training samples is unknown. The goal is to reveal the internal properties and laws of data through the learning of unmarked training samples, so as to provide a basis for further data analysis. Clustering is the most studied and widely used in this kind […]

Original link:http://tecdat.cn/?p=22609 abstract This paper provides a set of methods for analyzing various finite mixture models. It includes not only the traditional methods, such as the EM algorithm of univariate and multivariable normal mixture, but also some newly studied methods reflecting the finite mixture model. Many algorithms are EM algorithms or based on em like […]

[anatomy] cvpr2020 unsupervised domain adaptation via structurally regulated deep clustering This article is a 2020cvpr article. The article uses the clustering method for domain adaptation. The effect on common data sets has been outstanding for 20 years. Recent work is similar to this idea. Let’s investigate it. abstract Transfer learning solves the problem of inconsistent […]

Data mining refers to the process of searching hidden information from a large number of data through algorithms, which is usually related to computer science, and achieves the above objectives through many methods, such as statistics, online analysis and processing, information retrieval, machine learning, expert system (relying on past experience rules) and pattern recognition. I […]
