Programming 3 - kNN

Goal

• Learn to implement k-nearest neighbor classifier and radius-based nearest neighbor classifier.

• Improve performance by neighborhood size, and approximate nearest neighbors.

Readings

• Chapter 15 K-Nearest Neighbors,  Machine Learning with Python Cookbook 2nd,  Free O'Reilly Learning by FJU ID

Instructions

• Read the reading and practice all the Python codes with the IRIS dataset example.

• Exercise: Change the data to another Scikit-Learn toy dataset. Modify the Python codes to perform more analysis.  Analyze the results of output, explain the results, and improve the results.

Report: a separate and single web page that you

• • Write the goal of this assignment

  • Explain the kNN algorithm. Explain the Scikit-Learn functions of kNN.

  • Explain the Python codes. Upload code output results into your report web page. Explain the results of the output results

  • Clearly explain modified code segments written by you. Give some analysis in your report.

  • Give references to this assignment (teacher's readings, your readings)
