Prerequisites
Prerequisites: To feel comfortable in this course, you should have good knowledge of simple linear algebra and probability theory, as well as programming in Python. Additional knowledge of data structures will make many of the assignments easier to solve.
Mission & Content Summary
MISSION
Natural Language Processing tools are becoming ubiquitous: from everyday tools like Siri or Alexa to decision making processes in industry or politics and to text analysis tools in social science research. Machine-learning based text analysis tools provide a range of possibilities and are a growing field of expertise.
Whether it is the exploration of text to find structures and topics, or the construction of a classifier to predict the sentiment or author characterstics of a text, this course provides an overview and hands-on experience in all relevant techniques.
CONTENT SUMMARY
Preparation: how do I work with text:
- Data formats.
- Preprocessing.
- Storage and retrieval.
Exploration: exploring structure in the data:
- Clustering.
- Topic models.
- Word embeddings.
Prediction: finding patterns to impute new values:
- Text classification (sentiment analysis, author attributes).
- Logistic Regression.
- Perceptron.
- Feed-forward Neural Nets.
- Convolutional Neural Nets.
- Structured prediction (parts of speech, parsing, discourse).
- Structured perceptron.
- Recurent Neural Nets.
