之前有老师提出要做SOM分析，最后卡在code plot只能出segment plot却出不来line plot。查了下，没看到解决方案。今天看了下源码，设置了一个参数，得到趋势图。也顺便学习了SOM分析的整个过程，整理下来，以备以后用到。 SOM (Self-Organizing Feature Map,自组织特征图)是基于神经网络方式的数据矩阵和可视化方式。与其它类型的中心点聚类算法如K-me ...

My plan to reduce the 2.6 million Australian bureaucrats by 90 per cent was simple, just find people with better skills!

Abstract: In this paper, we present a class of codes, referred to as random staircase generator matrix codes (SGMCs), which have staircase-like generator matrices. In the infinite-length region, we ...

Abstract: In this paper, we propose a novel construction for secure distributed matrix multiplication (SDMM) based on algebraic geometry (AG) codes, which we call the PoleGap SDMM scheme. The proposed ...
