This is a workshop on using Machine Learning and Deep Learning Techniques to build Recommendation Systesm
- Theory: ML & DL Formulation, Prediction vs. Ranking, Similiarity, Biased vs. Unbiased
- Paradigms: Content-based, Collaborative filtering, Knowledge-based, Hybrid and Ensembles
- Data: Tabular, Images, Text (Sequences)
- Models: (Deep) Matrix Factorisation, Auto-Encoders, Wide & Deep, Rank-Learning, Sequence Modelling
- Methods: Explicit vs. implicit feedback, User-Item matrix, Embeddings, Convolution, Recurrent, Domain Signals: location, time, context, social,
- Process: Setup, Encode & Embed, Design, Train & Select, Serve & Scale, Measure, Test & Improve
- Tools: python-data-stack: numpy, pandas, scikit-learn, keras, spacy, implicit, lightfm
- Basics: Deep Learning
- AI Conference 2019: WhiteBoard Notes | In-Class Notebooks
