Exploration in recommender systems
Chen M. RecSys 2021 Amsterdam, the Netherlands, Sep 27-Oct 1, 2021) 551-553, 2021. Type: Proceedings
Classic arbitration between exploration and exploitation could overestimate the optimal recommendation based on “learning by experience”  and relying on the measurement of user exploration through four essential parameters: accuracy...

Concise guide to quantum computing: algorithms, exercises, and implementations
Kurgalin S., Borzunov S., Springer International Publishing, Cham, Switzerland, 2021. 136 pp. Type: Book (978-3-030650-51-3)
For quite some time it has often been difficult for students and young researchers interested in quantum computing to bridge the gap between computer science and quantum physics. What remains are the parallel evolutions of quantum computing techno...
