01_Machine Learning Approach for Sentiment Analysis
Machine Learning Approach for Sentiment Analysis This is an example of sentiment analysis using machine learning. The IMDB data set contains movie reviews labelled by sentiment. A Machine Learning algorithm is then trained to predict thesentiment of such reviews in the training set and applied to the reviews in the test set to evaluate its generalization performance.
