(Russian / Romanian / Belarussian translations by various people) Gnumpy is free software, but if you use it in scientific work that gets published, you should cite this tech report in your publication. Download: gnumpy.py (also be sure to have the most recent version of Cudamat) Documentation: here. Do you want to have both the compute power of GPU's and the programming convenience of Python numpy? Gnumpy + Cudamat will bring you that. Gnumpy is a simple Python module that interfaces in a way almost identical to numpy, but does its computations on your computer's GPU.
Gnumpy runs on top of, and therefore requires, the excellent cudamat library, written by Vlad Mnih. Gnumpy can run in simulation mode: everything happens on the CPU, but the interface is the same.

U.S. Census Return Rate Challenge (Visualization Competition) Note: The prediction phase of this competition has ended. Please join the visualization competition which ends on Nov. 11, 2012. This challenge is to develop a statistical model to predict census mail return rates at the Census block group level of geography. The Census Bureau will use this model for planning purposes for the decennial census and for demographic sample surveys.
The model-based estimates of predicted mail return will be publicly released in a later version of the Census "planning database" containing updated demographic data. Participants are encouraged to develop and evaluate different statistical approaches to proposing the best predictive model for geographic units. The intent is to improve our current predictive analytics.
Please note also that as described in the rules, only US citizens and residents are eligible for prizes. GE Quest - Let the Quests Begin! Neural Networks for Machine Learning - View Thread.

Kaggle: making data science a sport. PyBrain. Deep Belief Networks. A tutorial on Deep Learning. Complex probabilistic models of unlabeled data can be created by combining simpler models. Mixture models are obtained by averaging the densities of simpler models and "products of experts" are obtained by multiplying the densities together and renormalizing.
A far more powerful type of combination is to form a "composition of experts" by treating the values of the latent variables of one model as the data for learning the next model. The first half of the tutorial will show how deep belief nets -- directed generative models with many layers of hidden variables -- can be learned one layer at a time by composing simple, undirected, product of expert models that only have one hidden layer. It will also explain why composing directed models does not work. Would you like to put a link to this lecture on your homepage? Deep Learning. Backpropagation. The project describes teaching process of multi-layer neural network employing backpropagation algorithm. To illustrate this process the three layer neural network with two inputs and one output,which is shown in the picture below, is used: Each neuron is composed of two units.
First unit adds products of weights coefficients and input signals. The second unit realise nonlinear function, called neuron activation function. Signal e is adder output signal, and y = f(e) is output signal of nonlinear element. Signal y is also output signal of neuron. To teach the neural network we need training data set.
Propagation of signals through the hidden layer. Propagation of signals through the output layer. In the next algorithm step the output signal of the network y is compared with the desired output value (the target), which is found in training data set. It is impossible to compute error signal for internal neurons directly, because output values of these neurons are unknown. PyBrain. Introduction to Neural Networks.

An introduction to neural networks. Andrew Blais, Ph.D. (email@example.com)David Mertz, Ph.D. (firstname.lastname@example.org) Gnosis Software, Inc. June 2001 A convenient way to introduce neural nets is with a puzzle that they can be used to solve. Suppose that you are given, for example, 500 characters of code that you know to be either C, C++, Java or Python. Now, construct a program that identifies the code's language. One solution is to construct a neural net that learns to identify these languages. According to a simplified account, the human brain consists of about ten billion neurons, and a neuron is, on average, connected to several thousand other neurons. Threshold logic units The first step toward neural nets is to abstract from the biological neuron, and to focus on its character as a threshold logic unit (TLU).
A = (X1 * W1)+(X2 * W2)+... The threshold is called theta. Figure 1: Threshold logic unit, with sigma function (top) and cutoff function (bottom) A TLU can classify. Learning stuff During training, a neural net inputs: Neural Network Basics. David Leverington Associate Professor of Geosciences The Feedforward Backpropagation Neural Network Algorithm Although the long-term goal of the neural-network community remains the design of autonomous machine intelligence, the main modern application of artificial neural networks is in the field of pattern recognition (e.g., Joshi et al., 1997). In the sub-field of data classification, neural-network methods have been found to be useful alternatives to statistical techniques such as those which involve regression analysis or probability density estimation (e.g., Holmström et al., 1997). The potential utility of neural networks in the classification of multisource satellite-imagery databases has been recognized for well over a decade, and today neural networks are an established tool in the field of remote sensing.
The most widely applied neural network algorithm in image classification remains the feedforward backpropagation algorithm. 1 Neural Network Basics 2 McCulloch-Pitts Networks. UFLDL Tutorial - Ufldl. From Ufldl Description: This tutorial will teach you the main ideas of Unsupervised Feature Learning and Deep Learning. By working through it, you will also get to implement several feature learning/deep learning algorithms, get to see them work for yourself, and learn how to apply/adapt these ideas to new problems. This tutorial assumes a basic knowledge of machine learning (specifically, familiarity with the ideas of supervised learning, logistic regression, gradient descent). If you are not familiar with these ideas, we suggest you go to this Machine Learning course and complete sections II, III, IV (up to Logistic Regression) first.

This is going to be an ongoing article series about various aspects of Machine Learning. In the first post of the series I’m going to explain why I decided to learn and use R , and why it is probably the best statistical software for Machine Learning at this time. R vs. popular programming languages like Java Implementing Machine Learning algorithms is not an easy task because it requires a deep understanding of the inner workings of the algorithm.
Furthermore, it can make a big difference how the function of a Machine Learning algorithm is implemented in detail because the application of advanced mathematical tricks can enhance the performance of the algorithm substantially. R already provides sophisticated implementations of various Machine Learning algorithms and therefore relieves you from the tedious and error-prone task of implementing your own algorithms. R vs. R vs. R vs. Other reasons for R A great advantage of R is that scientists adopted it as their de facto standard. Machine learning in Python — scikit-learn 0.12.1 documentation.
