Cluster Analysis ML Skills Test

It is a technique used to group similar objects into clusters. When understanding complex information sets, this test is invaluable.

By dividing up your data into manageable clusters based on similarities and differences between objects - this method uncovers hidden patterns that could lead to important insights.‍

Why use iMocha's Cluster Analysis skills test?‍

This skills test evaluates a candidate's and employee's ability to work with clustering software to analyze data and detect patterns, build models, and perform data visualization.

Moreover, our tests are reliable because of the inbuilt cheating prevention tools such as window violation, image and video proctoring, etc.

Test Summary

The test assesses candidates and employees in the following attributes: -

  • A thorough understanding of concepts like distance metrics, clustering algorithms, and cluster validation metrics.
  • Proficiency in programming languages such as Python, R, or MATLAB.
  • Strong skills in selecting and evaluating clustering algorithms, including using metrics such as silhouette score, Calinski-Harabasz index, and Davies-Bouldin index.
  • Expertise in visualization techniques such as scatterplots, heatmaps, and dendrograms.
  • Understanding of specific algorithms and models such as K-Means, DBSCAN, and BIRCH, and the ability to explain why they are relevant to clustering analysis.

The test analytics feature also allows you to compare candidate scores and make informed decisions about who to hire and where to put extra training efforts.
