Algorithmic Music Discovery at Spotify

Today, Spotify has over 60 million active users and over 30 million
songs. One key mission of Spotify is to help users discover good
music, which is achieved by serving users good recommendations.
In this talk, I will introduce briefly the recommender system behind
the Discover feature in Spotify, and some challenges we have.

Search From the Trenches

What distinguished a search engine from a search solution? This talk focuses on the part of findability that a search engine just doesn't do well on its own. How can we solve that? What else do you need?

Deep Learning for Information Retrieval

From 2013 to 2020, the digital universe will grow by a factor of 10. Not only the size of data is changing, but also its shape: from mainly text-based to increasingly visual, and audio. Search engines are having a hard time to keep up. Deep Learning, a new branch of machine learning, is one way to deal with this enormous growth of information. In this talk I will give a brief introduction to deep learning, and explain how it can help in making content searchable through 2 specific deep-learning based approaches: multi-modal methods, which can learn a single united visual-semantic representation of text and images, as well as deep graph-based methods and textual embeddings, which can learn latent features of text, and can find disentangle and find structure in the chaos and make content understandable to search engines and users.

Clinical text retrieval - some methods and some applications

Electronic patient records contain a waste source of information, both in form of structured information as diagnosis codes, drug codes, lab values, time stamps, etc and unstructured in form of free text. Methods - both rule based and machine learning based for retrieving this information is presented. Applications as diagnosis codes assignment, hospital acquired infection detection and adverse drug event detection will be discussed.

Anders Friberg, KTH

Music Information Retrieval

The recent paradigm shift in music distribution has created a need for new methods of browsing, searching, and recommending music on the Internet. Given the size of current music databases, typically around 30 million songs or more, automatic methods are particularly useful. An overview of methods and challenges in the field with some snapshots from KTH research will be presented.

Magnus Sahlgren, Gavagai

Text analysis for Big Data

This lecture discusses some of the challenges we face when doing text analysis for Big Data. The lecture gives a brief overview of the technologies used by Gavagai, and touches upon notions such as Big Data, Text Analysis, Semantic Memories, and Deep Learning. We also give examples of real-world applications of text analysis.
