🧵 I recently dived into a rabbit hole when attempting to fix the tests for #sklearn's OLS and Ridge regression solvers.

On the theoretical side, I now understand that the minimum norm solution for the centered problem without intercept is also the minimum norm
solution for the original problem (with intercept). Ridge/OLS on centered X & y followed by intercept computation is the approach (hereafter name type "a") we have been using for years.

Really excited to attend #JupyterCon in Paris this year!

Vincent Maladiere and I will present a full day tutorial on predictive Survival Analysis and Competing Risks modeling with a Gradient Boosting model assembled from generic scikit-learn building blocks. We will also introduce many concepts and model evaluation methodology using specialized libraries such as lifelines and scikit-survival.

Here is the full agenda for this session:

#3goodthings today @3goodthings
1) I implemented the forward-backward #regression algorithm to use with #Sklearn at work, it was fun
2) I ate a cinnamon roll 😋
3) I had a deep conversation with my partner about my #bpd

Did you know that #sklearn pipelines that rely on k-nearest neighbors graph computation can swap the built-in exact neighbors search by an accelerated third-party method such as the one implemented with #numba in the #PyNNDescent project?

Somebody wrote here that "𝘮𝘶𝘴𝘪𝘤 𝘪𝘴 𝘫𝘶𝘴𝘵 #𝘮𝘢𝘵𝘩𝘦𝘮𝘢𝘵𝘪𝘤𝘴, 𝘣𝘶𝘵 𝘭𝘰𝘶𝘥𝘦𝘳". #Math is indeed beautiful.

Analyzing high-dimensional data (10^6 samples, 100+ features) in #Python, using #Sklearn Looking at that data thru a manifold, reducing the number of dimensions to 2 (e.g. a sheet of paper), sometimes to 3 (#3D model), with the help of #TSNE method.

It doesn't cease to amaze how many living creatures, leaves, insects I see in this unreal world😍

@talkpython @michaelaye Just tested on a simple #sklearn iris dataset test from https://panel.holoviz.org/gallery/simple/iris_kmeans.html , amazing.
#panel converts #ipython #notebook directly to #pyscript apps.
