Criticality-Based Varying Step-Number Algorithm for Reinforcement Learning
Yitzhak Spielberg, Amos Azaria
In the context of reinforcement learning we introduce the concept of criticality of a state, which indicates the extent to which the choice of action in that particular state influ…
Revelation of Task Difficulty in AI-aided Education
Yitzhak Spielberg, Amos Azaria
When a student is asked to perform a given task, her subjective estimate of the difficulty of that task has a strong influence on her performance. There exists a rich literature on…
The Concept of Criticality in AI Safety
Yitzhak Spielberg, Amos Azaria
When AI agents don't align their actions with human values they may cause serious harm. One way to solve the value alignment problem is by including a human operator who monitors a…
The Concept of Criticality in Reinforcement Learning
Yitzhak Spielberg, Amos Azaria
Reinforcement learning methods carry a well known bias-variance trade-off in n-step algorithms for optimal control. Unfortunately, this has rarely been addressed in current researc…
