Abstract
The invention relates to a coronavirus sequence recognition method based on a gated recurrent unit neural network. The coronavirus sequence recognition method comprises the following steps: S1, collecting data; S2, preprocessing the collected data, and performing data extraction from an original training sample to obtain a training set, a verification set and a test set; establishing an independent test set based on coronavirus sequences; S3, encoding each data set obtained in the S2, and establishing a classification model for training coronavirus sequences; S4, correcting the model; S5, counting an output score of the model to each sequence of a test set after the coronavirus sequence and the human genome sequence are merged; S6, setting a rejection interval according to the distributioncondition of the output score so as to reduce errors; S7, when the output score is larger than or equal to the upper limit threshold value of the rejection interval, judging the sequence to be a coronavirus sequence; and when the output score is less than or equal to the lower limit threshold of the rejection interval, judging that the sequence is a human genome sequence.
Description
technical field [0001] The present invention relates to the technical fields of neural network, data processing and computer simulation, and more specifically relates to a coronavirus sequence recognition method based on a gated recurrent unit neural network. Background technique [0002] Coronavirus (CoV) is a class of enveloped single-stranded positive-sense RNA viruses that cause a variety of diseases in mammals and birds. Some coronaviruses are highly contagious, pathogenic, and fatal in humans, and have a huge negative impact on national health, social stability, and national economic development. [0003] Real-time reverse transcription polymerase chain reaction (Real-time Reverse-transcription Polymerase Chain Reaction, RT-PCR) amplification method is the method of choice for the detection of coronaviruses. This method has the advantages of real-time monitoring, high sensitivity, and high specificity, but it also has some disadvantages, such as the inability to detec...
