Poker hands recognition (Machine Learning)

A few months ago I downloaded the scikit-learn package for Python, for those of you who might not be aware, scikit-learn is a powerful yet very simple package useful to apply machine learning. Basically they give you “all” the algorithms you may need and you “only” have to get the data and make it ready to feed into the scikit-learn algorithm.

Anyway, I only recently had time to check it out and write some code, furthermore only recently I found a great site full of sample datasets dedicated to machine learning (check it out here). Since the data from this great site is more or less in the right shape for being ready to import (.txt files or similar) the only task left to the programmer is to put it into numpy arrays.

This is one of my first attempt at generating a “real” machine learning program.

I won’t post the pre-settings script since it is pretty boring, instead I’ll briefly describe the pre-setting: basically, using a simple script I’ve splitted the training samples from the database in two .txt files trainingP.txt and target.txt respectively. TrainingP.txt contains the questions (the hands of poker) and target.txt contains the answers (=the score, that’s to say poker, full house etc… coded into numbers according to the description given in the database description file).

Below is the ml script: it is composed of 3 parts: setting, training and testing

setting: import the training sets and fit them into numpy arrays of the correct shape

training: fit the data into the model using scikit-learn

testing: test the algorithm and check what it has learned so far! Some statistics are printed, for reference. Check the results below!

So far the best score is 56.4%, I wonder if I did everything correctly! Anyway soon I will post a script with better results and achievements!

Below is the citation of the source of the database, according to their citation policy.

The name of the dataset is Poker Hand and it is from:
