GRU based recurrent neural network multi-label learning method

The invention provides a GRU based recurrent neural network multi-label learning method, which comprises the steps of S1, initializing a system parameter [theta]=(W, U, B); S2, inputting a sample {xi,yi}<i=1><N>, calculating a hidden state hT of the output of an RNN (Recurrent Neural Network) at each moment, wherein the sample xi belongs to R<M*1>, yi is a multi-label vector of the sample xi, andyi belongs to R<C*1>; S3, calculating a context vector hT and output zi of an output layer; S4, calculating the predicted output yi^, calculating the loss Li, and determining an objective function J;S5, solving the gradient of the system parameter [theta]=(W, U, B) according to a gradient descent method and a BPTT (Back-propagation Through Time) algorithm; S6, determining a learning rate [eta],and updating each weight gradient W=W-[eta]*[delta]W; S7, judging whether the neural network reaches stable or not, if so, executing a step S8, if not, returning the step S2, and iteratively updatingmodel parameters; and S8, outputting an optimization model. According to the invention, effective feature representation of the sample can be obtained by fully utilizing the RNN so as to improve the accuracy of multi-label classification. In addition, a problem of gradient disappearance is not easy to occur in back propagation.

Social short text sentiment classification method and device and storage medium

ActiveCN112214601AImproving the performance of sentiment polarity analysisComprehensive and varied descriptionData processing applicationsSemantic analysisClassification methodsEmotion classification
The invention discloses a social short text sentiment classification method and device and a storage medium, and the method comprises the steps: obtaining a text published by a user when the sentimenttendency of a social short text is automatically analyzed and mined; then extracting and calculating a text context sentiment feature value and a priori polarity sentiment feature value; using pre-training word vector models such as word2Vec and the like for training text word vector representation; using multi-window convolution operation for obtaining text semantic relations of different granularities; using a multi-head self-attention network for effectively capturing and memorizing text long-distance context semantic information, and avoiding the problem that a recurrent neural network cannot conduct parallel computing; using multi-layer convolution and pooling combination for abstracting text sentiment semantic representation from different levels; and finally combining sentiment feature vector representation of different levels, so that explicit and implicit sentiment semantic features contained in the text can be described more comprehensively and diverse, and the performance of short text sentiment polarity analysis is improved.

Storage cabinet door opening and closing control circuit and intelligent cabinet door opening and closing storage cabinet

The invention discloses a storage cabinet door opening and closing control circuit and an intelligent cabinet door opening and closing storage cabinet. The circuit comprises a power module used for dividing electric supply into three paths including touch switch power input, control circuit power input and motor power input. The touch switch power input is connected with a touch switch module used for sending cabinet door opening or closing signals. The control circuit power input is connected with a programmable control module used for receiving the cabinet door opening/closing signals and outputting motor forward rotation or reverse rotation signals. The motor power input is connected with a storage cabinet motor and a direction switch module. The direction switch module is used for controlling the motor to forwards rotate or reversely rotate according to the motor forward rotation or reverse rotation signals so that a cabinet door can be driven to be folded, ascend and be opened or to be unfolded, descend and be closed. The cabinet door of the intelligent cabinet door opening and closing storage cabinet can be intelligently folded and opened and unfolded and closed, and automatic position memorizing, intelligent jamming protection and other intelligent control can be achieved.

Detection method of sarcastic sentences in microblog comments involved in dynamic memory case descriptions

The invention relates to a method for detecting sarcastic sentences of microblog comments involved in dynamic memory case descriptions, and belongs to the technical field of natural language processing. The invention includes the steps of: constructing a satirical data set of microblog involved in the case; using word embedding and position embedding to respectively carry out feature encoding on the text of the microblog involved and the comments on the microblog involved, and introducing an attention mechanism into the microblog comment involved after the feature encoding; Through the dynamic memory mechanism, the text representation related to the microblog comments involved in the case is obtained; the obtained text representation and the comment representation are spliced ​​to obtain a new representation, and the representation is used as an input to train the model, and the model is used to detect the sarcasm of the microblog comments involved in the case. The present invention realizes the irony detection of the comment sentences involved in the case by taking the case description information as the background information, and detects the irony sentences from the obtained public opinion data, which provides support for the subsequent sentiment analysis.
