== Adding more Classification classes and implementing missing methods in statistics package ==
== Adding clustering {{Codeline|*Searcher}} classes in statistics package ==


Although a ClassificationKNN class was added in the latest statistics release (1.6.1), it still lacks several methods (only `predict` is available at the moment). This GSoC project aims at implementing more methods, such as crossval, cvloss, lime, loss, margin, partialDependence, plotPartialDependence, etc., as well as adding more classdefs related to classification classes, such as ClassificationGAM, ClassificationDiscriminant, ClassificationSVM, ClassificationNeuralNetwork, ClassificationNaiveBayes, etc. The statistics package, although heavily developed during the past years, still lacks a lot of classdef functionality. The scope is to implement classification class def objects and their relevant methods in a MATLAB compatible way.  
Although the statistics package already has {{Codeline|knnsearch}} and {{Codeline|rangesearch}} functions, it misses [https://docs.octave.org/latest/Creating-a-classdef-Class.html classdefs] for extending their functionality. Furthermore, the {{Codeline|KDTree}} method in the aforementioned functions is currently disabled, because it is very slow and poorly implemented (see GitHub issue [https://github.com/gnu-octave/statistics/issues/151 #151]). The goal of this project if to implement {{Codeline|KDTreeSearcher}}, {{Codeline|ExhaustiveSearcher}}, and {{Codeline|hnswSearcher}} classes (including their {{Codeline|knnsearch}} and {{Codeline|rangesearch}} methods) along with the {{Codeline|createns}} helper function. Beyond MATLAB compatibility, the KDTree implementation should ideally utilize a compiled oct library for faster construction and queries of points.

This project has two aims: (1) make changes to the Chebfun code to make it work on Octave and (2) improve Octave's classdef functionality.

Some initial steps toward to first goal can be found on [https://github.com/cbm755/chebfun/tree/octave_dev| this octave_dev branch].

The second goal will likely involve a collaborative effort because classdef is a priority on [https://hg.savannah.gnu.org/hgweb/octave/file/tip/etc/ROADMAP.md| Octave's Development Roadmap] and because other proposed projects also involve classdef.
