Check out our project, [KeystoneML](<a href="http:&#x2F;&#x2F;keystone-ml.org&#x2F;" rel="nofollow">http:&#x2F;&#x2F;keystone-ml.org&#x2F;</a>) - it&#x27;s geared to large scale machine learning in the realms of computer vision, NLP, and (soon) speech. The design is modular and engineering-friendly and is quite focused on real-world applications. (e.g. start with pictures, do the feature extraction, PCA, linear regression, etc.) and out comes a classifier.
