Today, give a try to Techtonique web app, a tool designed to help you make informed, data-driven decisions using Mathematics, Statistics, Machine Learning, and Data Visualization. Here is a tutorial with audio, video, code, and slides: https://moudiki2.gumroad.com/l/nrhgb. 100 API requests are now (and forever) offered to every user every month, no matter the pricing tier.
During the past few weeks, I’ve been adapting a Python version of the (seemingly abandoned?) official Stanford GLMNet Python package. Don’t try to build a programming interface on it yet, as it’s still “moving”.
GLMNet implements the entire lasso or elastic-net regularization path for linear regression, logistic and multinomial regression models, poisson regression and the cox model. My implementation is faithful to the R Fortran-based one, but:
- uses
numpyinstead ofscipy - uses
scikit-learnstyle, with a main classGLMNethaving methodsfitandpredict
If (like me) you’re fond of GLMNet and scikit-learn style, you may love this package. Here, I illustrate the usage of this “new” package, along with its use within the Techtonique ecosystem (nnetsauce and mlsauce).
!pip install nnetsauce
!pip install git+https://github.com/Techtonique/mlsauce.git --verbose --upgrade --no-cache-dir
!pip install git+https://github.com/thierrymoudiki/glmnetforpython.git --verbose --upgrade --no-cache-dir
