Class of artificial neural network A restricted Boltzmann machine (RBM) (also called a restricted Sherrington–Kirkpatrick model with external field or restricted stochastic Ising–Lenz–Little model) is a generative stochastic artificial neural network that can learn a probability distribution over its set of inputs.[1] RBMs were initially proposed under the name Harmonium by Paul Smolensky in 1986,[2] and rose to prominence after Geoffrey Hinton and collaborators used fast learning algorithms for them in the mid-2000s.
RBMs have found applications in dimensionality reduction,[3] classification,[4] collaborative filtering,[5] feature learning,[6] topic modelling[7] and even many body quantum mechanics.[8][9] They can be trained in either supervised or unsupervised ways, depending on the task. Restricted Boltzmann machines can also be used in deep learning networks. Structure[edit] of size . Of the matrix is associated with the connection between the visible (input) unit and the hidden unit . . Matlab Toolbox for Dimensionality Reduction – Laurens van der Maaten. The Matlab Toolbox for Dimensionality Reduction contains Matlab implementations of 34 techniques for dimensionality reduction and metric learning. A large number of implementations was developed from scratch, whereas other implementations are improved versions of software that was already available on the Web.
The implementations in the toolbox are conservative in their use of memory. The toolbox is available for download here. Please note I am no longer actively maintaining this toolbox. Your mileage may vary! Currently, the Matlab Toolbox for Dimensionality Reduction contains the following techniques: In addition to the techniques for dimensionality reduction, the toolbox contains implementations of 6 techniques for intrinsic dimensionality estimation, as well as functions for out-of-sample extension, prewhitening of data, and the generation of toy datasets. Usage The toolbox provides easy access to all these implementations.

Scikit-learn - Wikipedia. Python library for machine learning Overview[edit] The scikit-learn project started as scikits.learn, a Google Summer of Code project by French data scientist David Cournapeau. The name of the project stems from the notion that it is a "SciKit" (SciPy Toolkit), a separately developed and distributed third-party extension to SciPy.[5] The original codebase was later rewritten by other developers. In 2010, contributors Fabian Pedregosa, Gaël Varoquaux, Alexandre Gramfort and Vincent Michel, from the French Institute for Research in Computer Science and Automation in Saclay, France, took leadership of the project and released the first public version of the library on February 1, 2010.[6] In November 2012, scikit-learn as well as scikit-image, were described as two of the "well-maintained and popular" scikits libraries[update].[7] In 2019, it was noted that scikit-learn is one of the most popular machine learning libraries on GitHub.[8] Implementation[edit] Version history[edit]
Mahout: Scalable machine learning and data mining. K-Means is a simple but well-known algorithm for grouping objects, clustering. All objects need to be represented as a set of numerical features. In addition, the user has to specify the number of groups (referred to as k) she wishes to identify. Each object can be thought of as being represented by some feature vector in an n dimensional space, n being the number of all features used to describe the objects to cluster. The algorithm then randomly chooses k points in that vector space, these point serve as the initial centers of the clusters. After that, for each cluster a new center is computed by averaging the feature vectors of all objects assigned to it. Several tweaks concerning distance measure, initial center choice and computation of new average centers have been explored, as well as the estimation of the number of clusters k.

For the query language, we reuse the concepts of graph patterns (which is a key concept in many graph transformation tools) as a concise and easy way to specify complex structural model queries. High runtime performance is achieved by adapting incremental graph pattern matching techniques based on the Rete algorithm. We believe the average programmer using EMF models will like EMF-IncQuery for the following reasons: EMF-IncQuery User Documentation Contributors Guide Releases.

NumPy — Numpy. Welcome — Pylearn2 dev documentation. Warning This project does not have any current developer. We will continue to review pull requests and merge them when appropriate, but do not expect new development unless someone decides to work on it. There are other machine learning frameworks built on top of Theano that could interest you, such as: Blocks, Keras and Lasagne. Don’t expect a clean road without bumps! If you find a bug please write to pylearn-dev@googlegroups.com. If you’re a Pylearn2 developer and you find a bug, please write a unit test for it so the bug doesn’t come back!
Pylearn2 is a machine learning library. Researchers add features as they need them. There is no PyPI download yet, so Pylearn2 cannot be installed using e.g. pip. Git clone To make Pylearn2 available in your Python installation, run the following command in the top-level pylearn2 directory (which should have been created by the previous command): python setup.py develop --user Data path Ian J. Welcome to nolearn’s documentation! — nolearn 0.4 documentation. Python Tools for Machine Learning | CB Insights - Blog. Python is one of the best programming languages out there, with an extensive coverage in scientific computing: computer vision, artificial intelligence, mathematics, astronomy to name a few. Unsurprisingly, this holds true for machine learning as well. Of course, it has some disadvantages too; one of which is that the tools and libraries for Python are scattered. If you are a unix-minded person, this works quite conveniently as every tool does one thing and does it well.
However, this also requires you to know different libraries and tools, including their advantages and disadvantages, to be able to make a sound decision for the systems that you are building. Tools by themselves do not make a system or product better, but with the right tools we can work much more efficiently and be more productive. Therefore, knowing the right tools for your work domain is crucially important. Scikit-Learn Scikit Learn is our machine learning tool of choice at CB Insights. Statsmodels PyMC Shogun Gensim.
