Generalized Linear Models

This notebook introduces the algorithms within Dask-GLM for Generalized Linear Models.

Start Dask Client for Dashboard

Starting the Dask Client is optional. It will provide a dashboard which is useful to gain insight on the computation.

The link to the dashboard will become visible when you create the client below. We recommend having it open on one side of your screen while using your notebook on the other side. This can take some effort to arrange your windows, but seeing them both at the same is very useful when learning.

In [ ]:
from dask.distributed import Client, progress
client = Client(processes=False, threads_per_worker=4,
                n_workers=1, memory_limit='2GB')

Make a random dataset

In [ ]:
from dask_glm.datasets import make_regression
X, y = make_regression(n_samples=200000, n_features=100, n_informative=5, chunksize=10000)
In [ ]:
import dask
X, y = dask.persist(X, y)

Solve with a GLM algorithm

We also recommend looking at the "Graph" dashboard during execution if available

In [ ]:
import dask_glm.algorithms

b = dask_glm.algorithms.admm(X, y, max_iter=5)

Solve with a difference GLM algorithm

In [ ]:
b = dask_glm.algorithms.proximal_grad(X, y, max_iter=5)

Customizable with different families and regularizers

The Dask-GLM project is nicely modular, allowing for different GLM families and regularizers, including a relatively straightforward interface for implementing custom ones.

In [ ]:
import dask_glm.families
import dask_glm.regularizers

family = dask_glm.families.Poisson()
regularizer = dask_glm.regularizers.ElasticNet()

b = dask_glm.algorithms.proximal_grad(
    X, y,
