Abstract: A method for training a speech recognition model, a device and a storage medium, which relate to the field of computer technologies, and particularly to the fields of speech recognition technologies, deep learning technologies, or the like, are disclosed. The method for training a speech recognition model includes: obtaining a fusion probability of each of at least one candidate text corresponding to a speech based on an acoustic decoding model and a language model; selecting a preset number of one or more candidate texts based on the fusion probability of each of the at least one candidate text, and determining a predicted text based on the preset number of one or more candidate texts; and obtaining a loss function based on the predicted text and a standard text corresponding to the speech, and training the speech recognition model based on the loss function.

Abstract: The present disclosure provides a method and apparatus of fusing operators, an electronic device and a storage medium, which relates to fields of deep learning, artificial intelligence and knowledge graph. The method includes: determining operator groups to be fused, according to an operator graph to be processed, wherein each operator group of the operator groups includes at least two operators in the operator graph respectively; obtaining a fused operator corresponding to the each operator group respectively; and for the fused operator, replacing corresponding operators in the operator graph with the fused operator respectively, and coupling dependence edges of the corresponding operators to the any fused operator, wherein the corresponding operators include operators in the operator group corresponding to the fused operator.
