Classifier accuracy improvements

We have updated some of our most popular classifiers to give better results.

Our most popular classifier for sentiment has been updated to give better performance. The major difference is that the data has gone through a cleaning pass, removing non english texts (noise). And with a slightly improved feature extractor and optimized data we can expect better accuracy.

We’ve also updated the following popular classifiers to use a new feature extractor. The result is better accuracy.

We might update more classifiers in the future.
