Sentiment Polarity CoreML Demo
A Demo application using CoreML framework for sentiment polarity analysis.
Model
CoreML model was converted from Scikit-learn Pipeline using coremltools python package.
The model is based on LinearSVC classifier and is able to distinguish between positive and negative sentences with best CV score = 0.801013024602. It was trained using Epinions.com dataset with reviews of products and services. Accuracy can be improved by using TfidfVectorizer for feature extraction, but it's not supported by coremltools at the moment.
