LightFM is a Python implementation of a number of popular recommendation algorithms for both implicit and explicit feedback, including efficient implementation of BPR and WARP ranking losses. It's easy to use, fast (via multithreaded model estimation), and produces high quality results. It also makes it possible to incorporate both item and user metadata into the traditional matrix factorization a
A python library for decision tree visualization and model interpretation. Decision trees are the fundamental building block of gradient boosting machines and Random Forests(tm), probably the two most popular machine learning models for structured data. Visualizing decision trees is a tremendous aid when learning how these models work and when interpreting models. The visualizations are inspired b
This post originally appeared on the DataCamp blog. Big thanks to Karlijn and all the fine folks at DataCamp for letting us share with the Yhat audience! And be sure to check out DataCamp's other cheat sheets, as well. Scikit-Learn library Most of you who are learning data science with Python will have definitely heard…

Continuing analysis from last year: Top 20 Python Machine Learning Open Source Projects, t
Examining stats about your data can be helpful, but sometimes you need to find ways to visualize it too. Fortunately this data set only has one dependent variable, so we can toss it in a scatter plot to get a better idea of what it looks like. We can use the "plot" function provided by pandas for this, which is really just a wrapper for matplotlib. data.plot(kind='scatter', x='Population', y='Prof
