Machine Learning in Recommender Systems - Recombee

Abstract:
Recommender systems are one of the most successful and widespread application of machine learning technologies in business. You will learn basic machine learning algorithms that are used in recommender systems such as matrix factorization or association rules. We will discuss problems of proper evaluation of recommendation models generated by these algorithms both on offline data and online.
We will explain the cold start problem and how you can reduce it by employing attributes of items including deep learning embeddings. You can use deep learning extensively in recommender systems and we will demonstrate one very interesting use case of predicting next purchased item using modern convolutional and recurrent neural neural networks.
Recommender algorithms can be also combined into ensembles. We show how our AutoML optimizes algorithms for every different recommendation scenario.
Finally, we will talk about recommender systems based on reinforcement learning capable of optimizing long term goals and KPIs such as customer lifetime value.

Machine Learning Meetups (MLMU) is an independent platform for people interested in Machine Learning, Information Retrieval, Natural Language Processing, Computer Vision, Pattern Recognition, Data Journalism, Artificial Intelligence, Agent Systems and all the related topics. MLMU is a regular community meeting usually consisting of a talk, a discussion and a subsequent networking. At the end of the year 2016, MLMU spread also to Brno and Bratislava. Later on, Košice joined our MLMU family.
