WebJun 17, 2024 · Then, the distribution over classes for given Query input Q is the softmax over the inverse of distances between the query data embedding f(Q) and the prototype vectors V_c and that can be used as the basis for classification: P(y=c Q) = softmax(-d[f(Q), V_c]) Therefore, the closer f(Q) is to any V_c, the more likely Q is to be in this class. Web关于Q. 提到Q-learning，我们需要先了解Q的含义。 Q为动作效用函数（action-utility function），用于评价在特定状态下采取某个动作的优劣。它是智能体的记忆。 在这个问题中， 状态和动作的组合是有限的。所以我们可以把Q当做是一张表格。 staycity apartments deptford https://dvbattery.com
