The invention relates to the technical field of
artificial intelligence, can be applied to business scenes of financial science and technology,
medical health and the like, and discloses an enhanced decision method, device, equipment and medium based on thinking chain
annotation, which comprises the following steps: extracting core information features to generate a structured
data set, loading a
basic language model and executing supervision
fine tuning to generate a fine-tuned model, fusing multi-
modal input to generate fusion features, constructing a state observation space to receive the fusion features as input, generating reward signals based on a double reward mechanism and optimizing
model parameters to generate an optimized model, deploying a monitoring module to dynamically adjust parameter configuration to generate an adaptive
decision model, and outputting a decision response result. According to the method, multi-
source data extraction, structured expression, multi-
modal fusion,
reinforcement learning optimization and dynamic adaptive mechanism fusion are carried out, so that the understanding ability of the model to complex data, reasoning transparency and the adaptive ability of the model to coping with environmental changes are remarkably improved.
