This is a Python package for machine learning built with the help of SciPy.It has lot of classification, regression and clustering algorithms. This also includes support vector machines, logistic regression, naive Bayes, random forests, gradient boosting, k-means and DBSCAN. This package was initially designed to take care of Python statistical/numerical and machine learning/scientific libraries NumPy and SciPy.
Pylearn2 is the easiest machine learning package in python.
NUPIC means Numenta Platform for Intelligent Computing. It is a machine learning intelligence platform. It incorporates the HTM learning algorithms. HTM is one of the best computational concept of the neocortex and neural networks. In the nucleus of HTM, theer are various time-based continuous learning algorithms. These algorithms store and recalculate many spatial and temporal patterns. This python analytics package is mostly used in different problems such as anomaly detection and prediction of streaming data sources.
Nilearn is a Python package meant for easiest analytical learning on NeuroImaging data. It utilizes scikit-learn Python modules for multivariate statistics along with predictive modeling, classification, decoding, or connectivity analysis.
PyBrain means Python-Based Reinforcement Learning, Artificial Intelligence and Neural Network Library. It the best package for machine learning algorithms and extremely easy to use.
There are very few module in python which are good in web mining. Pattern is one of them. It has amazing features such as NLP, network analysis and data mining. It has also enhaced features like support vector machines and classification techniques leveraging support vector machine, KNN, perceptron and SVM.
Fuel provides your machine learning models with the data they need to learn. it has interfaces to common datasets such as MNIST, CIFAR-10 (image datasets), Google’s One Billion Words (text). It gives you the ability to iterate over your data in a variety of ways, such as in minibatches with shuffled/sequential examples
Bob is a free signal-processing and machine learning toolbox The toolbox is written in a mix of Python and C++ and is designed to be both efficient and reduce development time. It is composed of a reasonably large number of packages that implement tools for image, audio & video processing, machine learning and pattern recognition
Skdata is a library of data sets for machine learning and statistics. This module provides standardized Python access to toy problems as well as popular computer vision and natural language processing data sets.
Milk is a machine learning toolkit in Python. Its focus is on supervised classification with several classifiers available: SVMs, k-NN, random forests, decision trees. It also performs feature selection. These classifiers can be combined in many ways to form different classification systems.For unsupervised learning, milk supports k-means clustering and affinity propagation.
IEPY is an open source tool for Information Extraction focused on Relation Extraction
It’s aimed at users needing to perform Information Extraction on a large dataset. scientists wanting to experiment with new IE algorithms.
Quepy is a python framework to transform natural language questions to queries in a database query language. It can be easily customized to different kinds of questions in natural language and database queries. So, with little coding you can build your own system for natural language access to your database.
Currently Quepy provides support for Sparql and MQL query languages, with plans to extended it to other database query languages.
Hebel is a library for deep learning with neural networks in Python using GPU acceleration with CUDA through PyCUDA. It implements the most important types of neural network models and offers a variety of different activation functions and training methods such as momentum, Nesterov momentum, dropout, and early stopping.
Its a library consisting of useful tools and extensions for the day-to-day data science tasks.
This package contains a number of utility modules that are helpful with machine learning tasks. Most of the modules work together with scikit-learn, others are more generally useful.
Ramp is a python library for rapid prototyping of machine learning solutions.
