TLDR
This work shows that algorithms that fit the Statistical Query model can be written in a certain "summation form," which allows them to be easily parallelized on multicore computers and shows basically linear speedup with an increasing number of processors.Abstract:
We are at the beginning of the multicore era. Computers will have increasingly many cores (processors), but there is still no good programming framework for these architectures, and thus no simple and unified way for machine learning to take advantage of the potential speed up. In this paper, we develop a broadly applicable parallel programming method, one that is easily applied to many different learning algorithms. Our work is in distinct contrast to the tradition in machine learning of designing (often ingenious) ways to speed up a single algorithm at a time. Specifically, we show that algorithms that fit the Statistical Query model [15] can be written in a certain "summation form," which allows them to be easily parallelized on multicore computers. We adapt Google's map-reduce [7] paradigm to demonstrate this parallel speed up technique on a variety of learning algorithms including locally weighted linear regression (LWLR), k-means, logistic regression (LR), naive Bayes (NB), SVM, ICA, PCA, gaussian discriminant analysis (GDA), EM, and backpropagation (NN). Our experimental results show basically linear speedup with an increasing number of processors.read more

Scalable and Numerically Stable Descriptive Statistics in SystemML
TL;DR: This paper describes the experience in implementing descriptive statistics in SystemML and elaborate on how to overcome the two major challenges: achieving numerical stability while operating on large data sets in a distributed setting of MapReduce and designing scalable algorithms to compute order statistics inMapReduce.

Minibatch and Parallelization for Online Large Margin Structured Learning
Kai Zhao,Liang Huang +1 more
TL;DR: It is shown that, unlike previous methods, minibatch learning (in serial mode) actually improves the converged accuracy for both perceptron and MIRA learning, and when combined with simple parallelization, minIBatch leads to very significant speedups on stateof-the-art parsing and tagging systems.

Sparse Online Learning via Truncated Gradient
TL;DR: This paper proposed a truncated gradient to induce sparsity in the weights of online learning algorithms with convex loss and proved that small rates of sparsification result in only small additional regret with respect to typical online learning guarantees.

Learning representations by back-propagating errors
TL;DR: Back-propagation repeatedly adjusts the weights of the connections in the network so as to minimize a measure of the difference between the actual output vector of the net and the desired output vector, which helps to represent important features of the task domain.
