Many practical data-processing algorithms fail to execute efficiently on general-purpose CPUs (Central Processing Units) due the sequential matter of their operations and memory bandwidth limitations. To achieve desired performance levels, reconfigurable (FPGA (Field-Programmable Gate Array)-based) hardware accelerators are frequently explored that permit processing units’ architectures be bett...

Recommender systems (RSs) have become an inseparable part of our everyday lives. They help us find favorite items to purchase, friends on social networks, and movies watch. Traditionally, the recommendation problem was considered be a classification or prediction problem, but it is now widely agreed that formulating as sequential decision can better reflect user-system interaction. Therefore, f...
