The Parallel Problems Server: an Interactive Tool for Large Scale Machine Learning

Charles Lee Isbell Jr., Parry Husbands
1999 Neural Information Processing Systems  
For example, we perform independent components analysis on very large text corpora consisting of tens of thousands of documents, making minimal changes to the original Bell and Sejnowski Matlab source  ...  We describe the Parallel Problems Server (PPServer) and MATLAB*P. In tandem they allow users of networked computers to work transparently on large data sets from within Matlab.  ...  The task in text retrieval is to find the subset of a collection of documents relevant to a user's information request. Standard approaches are based on the Vector Space Model (VSM).  ...

A comparison of cost construction methods onto a C6678 platform for stereo matching

Judicael Menant, Guillaume Gautier, Jean-Francois Nezan, Muriel Pressigout, Luce Morin
2016 2016 Conference on Design and Architectures for Signal and Image Processing (DASIP)  
This paper focuses on comparing the efficiency of different cost construction methods implemented on a Digital Signal Processor (DSP) C6678 platform.  ...  Three cost construction algorithms based on census, Sum of Absolute Differences (SAD) and Mutual Information (MI) have been compared in terms of output quality and execution time.  ...  Most of local stereo matching algorithms have their cost computed independently for each disparity level. Those algorithms can be parallelized along their disparity levels.  ...
