Hierarchical Clustering – Dendrograms Using Scipy and Scikit-learn in Python – Tutorial 24




[ad_1]

In this Tutorial about python for data science, You will learn about how to do hierarchical Clustering using scikit-learn in Python, and how to generate dendrograms using scipy in jupyter notebook.

This is the 24th Video of Python for Data Science Course! In This series I will explain to you Python and Data Science all the time! It is a deep rooted fact, Python is the best programming language for data analysis because of its libraries for manipulating, storing, and gaining understanding from data. Watch this video to learn about the language that make Python the data science powerhouse. Jupyter Notebooks have become very popular in the last few years, and for good reason. They allow you to create and share documents that contain live code, equations, visualizations and markdown text. This can all be run from directly in the browser. It is an essential tool to learn if you are getting started in Data Science, but will also have tons of benefits outside of that field. Harvard Business Review named data scientist “the sexiest job of the 21st century.” Python pandas is a commonly-used tool in the industry to easily and professionally clean, analyze, and visualize data of varying sizes and types. We’ll learn how to use pandas, Scipy, Sci-kit learn and matplotlib tools to extract meaningful insights and recommendations from real-world datasets.

    Why did you import fcluster? I don’t see you using it…

    How can I built user defined functions for H clustering….. Can anyone provide a link… For reference code of average linkage H clustering

    how to get tree between depth 500 to 150 with count and cluster details?

    Thank you for the video , I wanted to know your code to get the name of elements within each cluster ( for return data for exemple , we want to know the stocks within each cluster ; theirs names..) ?

    excuse me, why on sm.accuracy_score(y, Hclustering.labels_).

    ValueError: Classification metrics can't handle a mix of continuous and multiclass targets

    thanks

    Follow up of this video? I understood how to get dendrograms and decide at which point to cut. But after this, how do I see the cluster? I want to extract rules based on this clustering so i want to know which parameter's which values fall in which cluster. How to do that?

    Video is too long. Too much time explaining concept. Where is the code? Hahahaha.

    Hierarchical clustering is explained nicely. Could you please share the mtcars data to gullapallisudhir@gmail.com

    Thank you very much. But you can explain more detail about the axis in dendrogram? Like each number in x axis stands for? or (number) in axis stand for.

    Hi I'm a beginner at this but I was just wondering how come you specified the number of clusters? I was under the impression that hierarchical clustering meant that the machine is allowed to decide how many clusters to create based on its own algorithms.

    Hi! I am using my own data set for this. When I gave
    x = data.ix [:, (1,2,3,4,5,6,7,8)].values
    y = data.ix [:, :].values
    I'm having an error of 'AttributeError: 'list' object has no attribute 'ix'. Could you please suggest me anything to solve this error??
