Some algorithms are "how-to" examples

[poyea]

In our Contributing Guidelines:

Algorithms in this repo should not be how-to examples for existing Python packages. Instead, they should perform internal calculations or manipulations to convert input values into different output values. Those calculations or manipulations can use data types, classes, or functions of existing Python packages but each algorithm in this repo should add unique value.

And after some investigation like #6201, one can find some implementations that resemble online tutorials or are too trivial. In #6201, machine_learning/support_vector_machines.py is removed. It should be migrated to a much detailed implementation of SVM instead of importing packages.

Migration list:

• machine_learning/support_vector_machines.py

I am currently trying to implement it using SciPy (for minimization and maximization). Will keep you updated with the advancement.

[Bjiornulf]

Maybe the following files should be added to the migration list

• machine_learning/gaussian_naive_bayes.py
• machine_learning/gradient_boosting_regressor.py
• machine_learning/multilayer_perceptron_classifier.py
• machine_learning/polymonial_regression.py and has typos in name and file (polymonial -> polynomial)
• machine_learning/random_forest_classifier.py
• machine_learning/random_forest_regressor.py

[Sharukpy]

check the typos and try using with different libraries.

[shrutiiivij]

there are lots of pre define dictionary available in the python so we can use some other sort of libraries.

[Bjiornulf]

@Sharukpy @shrutiiivij I don't understand your point... Changing up libraries doesn't make those files any less "how-to" examples. There are no algorithms being implemented in the files, rather using well-known libraries to do the job. Correct me if I'm wrong, but this repository is about re-implementing algorithms in Python, so that people can actually understand what is happening under the hood (to some extent).

fuzzy_logic/fuzzy_operations.py should also be added to the migration list. The file has no algorithm functions (or any functions for that matter) and all the fuzzy logic operations are simply performed using functions from the skfuzzy module.

@cclauss We should reopen this issue since there are still quite a few how-tos, especially in machine_learning/

[tianyizheng02]

We can add computer_vision/cnn_classification.py and machine_learning/lstm/lstm_prediction.py to the list as well

[tianyizheng02]

@cclauss Could we reopen this issue since most of the "algorithms" listed here are still how-tos?
