代码说明:

  Python密度聚类 最近在Science上的一篇基于密度的聚类算法《Clustering by fast search and find of density peaks》引起了大家的关注(在我的博文“论文中的机器学习算法——基于密度峰值的聚类算法”中也进行了中文的描述)。于是我就想了解下基于密度的聚类算法,熟悉下基于密度的聚类算法与基于距离的聚类算法,如K-Means算法之间的区别。 基于密度的聚类算法主要的目标是寻找被低密度区域分离的高密度区域。与基于距离的聚类算法不同的是,基于距离的聚类算法的聚类结果是球状的簇,而基于密度的聚类算法可以发现任意形状的聚类,这对于带有噪音点的数据起着重要的作用。(The main goal of the density based clustering algorithm is to find high density regions separated by low density regions. Different from distance based clustering algorithm, the clustering results based on distance clustering algorithm are spherical clusters, and density based clustering algorithm can detect clustering of arbitrary shapes, which plays an important role in data with noisy points.)

    说明:  使用协同过滤的推荐系统测试代码Predicting movie ratings using collaborative filtering and latent concept extractors based on matrix decomposition methods like SVD and CUR on the movielens-100k dataset The project explores techniques for predicting unknown user ratings based on a large dataset of users and movie ratings.(Recommender-SystemsWe used 6 different recommender methods to predict user ratings across the data sets. Namely we set up Collaborative Filtering along with its baseline variant and Matrix decomposition techniques like Singular Value Decomposition and CUR. Moreover, we also implemented dimensionality reduction in these matrix decomposition techniques which preserved 90% of the energy so as to increase the computational efficiency while keeping the accuracy similar for these methods.)

  • Python
    介绍一些Python 的背景知识,包括Python、Python 的起源和它的一些关健特性。一旦你来了兴致,我们就会向你介绍怎样获得Python 以及如何在你的系统上安装并运行它。本章最后的练习将会帮助你非常自如地使用Python,包括使用交互式解释器以及创建并运行脚本程序。(Some Python background knowledge, including Python, Python' s origins and its Key characteristics. Once you got into high spirits, we will introduce you how to get the Python and how to install and run it on your system. The chapter concludes with exercises will help you very comfortable using Python, including the use of an interactive interpreter, as well as create and run scripts.)
