[jira] [Updated] (HAMA-681) Multi Layer Perceptron
[ https://issues.apache.org/jira/browse/HAMA-681?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Edward J. Yoon updated HAMA-681:
--------------------------------
Affects Version/s: (was: 0.5.0)
> Multi Layer Perceptron
> -----------------------
>
> Key: HAMA-681
> URL: https://issues.apache.org/jira/browse/HAMA-681
> Project: Hama
> Issue Type: New Feature
> Components: machine learning
> Reporter: Christian Herta
>
> Implementation of a Multilayer Perceptron (Neural Network)
> - Learning by Backpropagation
> - Distributed Learning
> The implementation should be the basis for the long range goals:
> - more efficent learning (Adagrad, L-BFGS)
> - High efficient distributed Learning
> - Autoencoder - Sparse (denoising) Autoencoder
> - Deep Learning
>
> ---
> Due to the overhead of Map-Reduce(MR) MR didn't seem to be the best strategy to distribute the learning of MLPs.
> Therefore the current implementation of the MLP (see MAHOUT-976) should be migrated to Hama. First all dependencies to Mahout (Matrix-Library) must be removed to get a standalone MLP Implementation. Then the Hama BSP programming model should be used to realize distributed learning.
> Different strategies of efficient synchronized weight updates has to be evaluated.
