Classification: CPC G | IPC G

Claim 12:
13. A non-transitory computer readable storage medium, storing computer readable instructions, wherein, the computer readable instructions, when executed by a processor, are configured to cause the processor to perform:
respectively processing a media object by using a plurality of natural language description (NLD) models to obtain a plurality of first feature vectors corresponding to a plurality of feature types;
fusing the plurality of first feature to obtain a second feature vector;
generating a NLD for the media object according to the second feature vector, the NLD being used for expressing the media object in natural language,
wherein, before the respectively processing the media object by using the plurality of NLD models, training each model of a plurality of initial NLD models by using a sample, to obtain a plurality of first models whose first loss function meets a first preset condition, the first loss function being a loss function configured according to each model of the plurality of initial NLD models;
training each joint model of a plurality of joint models by using the sample, to obtain a plurality of second models whose second loss function meets a second preset condition, the each joint model of the plurality of joint models being a model obtained by cascading one of the first models and a reconstructor model, the reconstructor model being configured to reconstruct a feature of the sample according to a description result outputted by the first model, and the second loss function being a loss function configured according to the each joint model; and
training the plurality of second models, to obtain a plurality of NLD models whose evaluation parameter meets a third preset condition.
