License: MIT URL: http://glm-tools.github.io/pyglmnet/ Source0: https://mirrors.nju.edu.cn/pypi/web/packages/b3/b4/862550f7a6289752abd9c5ceb534259530c57a930371485c0704944ec1d4/pyglmnet-1.1.tar.gz BuildArch: noarch %description A python implementation of elastic-net regularized generalized linear models ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ |License| |Travis| |Codecov| |Circle| |Gitter| |DOI| `[Documentation (stable version)]`_ `[Documentation (development version)]`_ `Generalized linear models `__ are well-established tools for regression and classification and are widely applied across the sciences, economics, business, and finance. They are uniquely identifiable due to their convex loss and easy to interpret due to their point-wise non-linearities and well-defined noise models. In the era of exploratory data analyses with a large number of predictor variables, it is important to regularize. Regularization prevents overfitting by penalizing the negative log likelihood and can be used to articulate prior knowledge about the parameters in a structured form. Despite the attractiveness of regularized GLMs, the available tools in the Python data science eco-system are highly fragmented. More specifically, - `statsmodels `__ provides a wide range of link functions but no regularization. - `scikit-learn `__ provides elastic net regularization but only for linear models. - `lightning `__ provides elastic net and group lasso regularization, but only for linear and logistic regression. **Pyglmnet** is a response to this fragmentation. It runs on Python 3.5+, and here are some of the highlights. - Pyglmnet provides a wide range of noise models (and paired canonical link functions): ``'gaussian'``, ``'binomial'``, ``'probit'``, ``'gamma'``, '``poisson``', and ``'softplus'``. - It supports a wide range of regularizers: ridge, lasso, elastic net, `group lasso `__, and `Tikhonov regularization `__. - Pyglmnet's API is designed to be compatible with scikit-learn, so you can deploy ``Pipeline`` tools such as ``GridSearchCV()`` and ``cross_val_score()``. - We follow the same approach and notations as in `Friedman, J., Hastie, T., & Tibshirani, R. (2010) `__ and the accompanying widely popular `R package `__. - We have implemented a cyclical coordinate descent optimizer with Newton update, active sets, update caching, and warm restarts. This optimization approach is identical to the one used in R package. - A number of Python wrappers exist for the R glmnet package (e.g. `here `__ and `here `__) but in contrast to these, Pyglmnet is a pure python implementation. Therefore, it is easy to modify and introduce additional noise models and regularizers in the future.
