Problems solved by technology

The disadvantage of this method is that it is only suitable for problems with low dimensionality of the state space
But its problem is: the specific form of many fitting functions needs to be manually set by experienced designers
This setting depends on personal experience, and it is often difficult to form a good approximation to the "true" Q value (here refers to the theoretically accurate representation), which will reduce the quality of the final decision

Embodiment Construction

[0021] The present invention will be further described in detail with reference to the accompanying drawings and embodiments.

[0022] The multi-layer classification network based on fuzzy adaptive resonance theory includes two modules: multi-layer classification network module and Q-learning module. The two need to work together, as in figure 1 shown. In this structure, a multi-layer classification network module inputs the state and uses an adaptive classification function to classify the input. This process is equivalent to dividing the state space into regions, and the states in each region have similar characteristics. The Q learning module calculates the Q value according to the partition of the state space by the multi-layer classification network, and calculates the best action strategy according to the Q value. This process is repeated until the Q learning module obtains a fitting Q function with a stable value.

Abstract

The invention discloses a Q function adaptive learning method based on a multilayer classification network, comprising the following steps: S1, training a multilayer classification network; and S2, using the multilayer classification network for work. Through the establishment of a hierarchical classification network, adaptive partitioning of a problem space is realized. Compared with an unimproved fuzzy adaptive resonance classification network, the partitioning mode is more flexible and can be used to get a better Q value fitting function. The embodiment shows that the method has stronger performance in acquisition of an optimal action strategy.

Description

technical field [0001] The invention belongs to the field of intelligent decision-making, and in particular relates to a method for implementing self-adaptive learning of a Q function in a Q-Learning algorithm by using a multi-layer classification network. Background technique [0002] Q-learning is a kind of reinforcement learning technology, and it is the most widely used reinforcement learning technology. The goal of Q-learning is to find a Q utility function (hereinafter referred to as "Q function") for the problem space, and map the <state, action> pair to a specific utility value (hereinafter referred to as "Q value"). Once the Q-function is obtained, the optimal action strategy in any state can be determined, so this method is widely used as a solution framework for decision-making problems. However, for a decision problem with a continuous state space (hereinafter referred to as "continuous problem"), it is difficult to quickly obtain the Q function. [0003]...
