Embodiment Construction
[0076] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0077] An embodiment of the present invention provides a meta-learning method for a cold-start recommendation system, referring to Figure 1, figure 1 It is a schematic flowchart of the first embodiment of the meta-learning method of the cold-start recommendation system of the present invention.
[0078] In this embodiment, the meta-learning method of the cold-start recommendation system includes the following steps:
[0079] Step S10: Extract the semantic enhancement task constructor of the meta path from the configuration file to obtain semantic enhancement task data.
[0080] Understandably, most traditional cold-start recommender systems learn global meta-parameters via a meta-learner to initialize the base model f θ , therefore, the global meta-parameter θ is also called a global prior, which is optimized across...
