1. Binary state compression Binary state compression refers to compressing a file with a length of m m The bool array of m uses a m m A method of representing and storing m-bit binary integers. The following bit operations can be used to access the corresponding subscript elements in the original bool array. Operation […]

Use Python for normality test, variance homogeneity test, one-way ANOVA, pairwise comparison
Introduction One-way ANOVA is a parametric test, Used to statistically infer whether the overall means of different groups (number of groups ≥ 2) are the same. Conditions of use The use of this statistical inference method requires the following conditions to be met: ① Continuous data: The data to be analyzed must be continuous data, […]
Read “Improved Deep Hashing with Soft Pairwise Similarity for Multi-label Image Retrieval”
Introduction Existing traditional hashes only need at least one label to match, so in the example shown in the figure, both a-b and a-c are considered to match This makes it impossible to top1 sort the similarity of multi-label pairs, so a soft definition of pairwise similarity is proposed for the semantic labels held by […]

Talk about pairwise, pointwise, listwise of sorting algorithm
NewBeeNLP dry goods Author: DOTA Hello everyone, this is NewBeeNLP. Recently, due to some adjustments in work, it has been a long time since I updated the article and summarized some personal experience. I just have time in the afternoon. I looked at some problems and discussions on various channels and saw a familiar problem. […]
