You're drowning in new Data Science technologies to learn. How can you stay afloat and master them all?
I’d always recommend to start with an application you are passionate about or is in line with your current professional goals - examples could include a recommender system or predictive model , a summarization task etc. Understand how you will evaluate quality (if you don’t have a handle on metrics make sure you understand those). Then play around using different techniques to solve a problem. Ideally use open source in this journey. It gives you the opportunity to go one level deeper and even modify the library and understand algorithms. Use online courses from top AI programs as a companion to learn in this journey.

Learning to Rank for Robust Question Answering
ACM International Conference on Information and Knowledge Management (CIKM)
This paper aims to solve the problem of improving the ranking of answer candidates for factoid based questions in a state-of-the-art Question Answering system. We first provide an extensive comparison of 5 ranking algorithms on two datasets – from the Jeopardy quiz show and a medical domain. We then show the effectiveness of a cascading approach, where the ranking produced by one ranker is used as input to the next stage. The cascading approach shows sizeable gains on both datasets. We finally…
This paper aims to solve the problem of improving the ranking of answer candidates for factoid based questions in a state-of-the-art Question Answering system. We first provide an extensive comparison of 5 ranking algorithms on two datasets – from the Jeopardy quiz show and a medical domain. We then show the effectiveness of a cascading approach, where the ranking produced by one ranker is used as input to the next stage. The cascading approach shows sizeable gains on both datasets. We finally evaluate several rank aggregation techniques to combine these algorithms, and find that Supervised Kemeny aggregation is a robust technique that always beats the baseline ranking approach used by Watson for the Jeopardy competition. We further corroborate our results on TREC
Question Answering datasets.
