WebMar 27, 2024 · In Deep Reinforcement Learning the whole network is commonly trained in an end-to-end fashion, where all network parameters are updated only using the scalar … WebScalar rewards (where the number of rewards n = 1) are a subset of vector rewards (where the number of rewards n ≥ 1). Therefore, intelligence developed to operate in the context of multiple rewards is also applicable to situations with a single scalar reward, as it can simply treat the scalar reward as a one-dimensional vector.
