Comparative Explanations of Recommendations
As recommendation is essentially a comparative (or ranking) process, a good explanation should illustrate to users why an item is believed to be better than another, i. e., comparative explanations about the recommended items.
Reversible Action Design for Combinatorial Optimization with Reinforcement Learning
Combinatorial optimization problem (COP) over graphs is a fundamental challenge in optimization.
Learning to Structure Long-term Dependence for Sequential Recommendation
To better model the long-term dependence structure, we propose a GatedLongRec solution in this work.
