Keras sequential model8/24/2023 ![]() Bud Tingwell gives a touching performance as Will, a widower struggling to cope with his wife's death. Although, only 15 minutes long, Griffiths manages to capture so much emotion and truth onto film in the short space of time. A heartwarming story about coping with grief and cherishing the memory of those we've loved and lost. ![]() Rachel Griffiths writes and directs this award winning short film. The aclImdb/train/pos and aclImdb/train/neg directories contain many text files, each of which is a single movie review. ![]() Train_dir = os.path.join(dataset_dir, 'train') Let's download and extract the dataset, then explore the directory structure. The training and testing sets are balanced, meaning they contain an equal number of positive and negative reviews. These are split into 25,000 reviews for training and 25,000 reviews for testing. You'll use the Large Movie Review Dataset that contains the text of 50,000 movie reviews from the Internet Movie Database. This is an example of binary-or two-class-classification, an important and widely applicable kind of machine learning problem. This notebook trains a sentiment analysis model to classify movie reviews as positive or negative, based on the text of the review. At the end of the notebook, there is an exercise for you to try, in which you'll train a multi-class classifier to predict the tag for a programming question on Stack Overflow. You'll train a binary classifier to perform sentiment analysis on an IMDB dataset. This tutorial demonstrates text classification starting from plain text files stored on disk.
