Many researchers addressed Random Projection for text data for text mining, text classification and/or dimensionality reduction. Text and document, especially with weighted feature extraction, can contain a huge number of underlying features. Sentiment classification is a type of text classification in which a given text is classified according to the sentimental polarity of the opinion it contains. Text Classification. The basic idea is that semantic vectors (such as the ones provided by Word2Vec) should preserve most of the relevant information about a text while having relatively low dimensionality which allows better machine learning treatment than straight one-hot encoding of words. The heart of building machine learning tools with Scikit-Learn is the Pipeline. To demonstrate text classification with Scikit Learn, we'll build a simple spam filter. Before fully implement Hierarchical attention network, I want to build a Hierarchical LSTM network as a base line. The classifier makes the assumption that each new complaint is assigned to one and only one category. Starter code to solve real world text data problems.
