WebDec 26, 2024 · We develop an approach for solving time-consistent risk-sensitive stochastic optimization problems using model-free reinforcement learning (RL). Specifically, we … WebConvex is used to describe a shape that curves inward, like a sideview mirror of a car. Concave is the opposite: a shape that curves outward. An American football is a good example of this. Both convex and concave shapes are commonly used in engineering, and most often in the design of lenses.
