Wavelet Transform Artificial Intelligence Algorithm-Based Data Mining Technology for Norovirus Monitoring and Early Warning

Abstract

Norovirus monitoring and early warning can be used for diagnosis without etiological testing, and the treatment of this disease does not require the antibiotics. It often occurs in preschool children and affects their growth and development, so the coping measures for this disease are more prevention than treatment. In this study, the clinical data of 2133 children with diarrhea were collected. Based on the artificial intelligence (AI) algorithm of wavelet transform, a related model for data mining and processing of children’s intestinal ultrasound images and stool specimens was constructed. Then, the norovirus infection trend was warned based on the wavelet analysis algorithm model. The results showed that the intestinal ultrasound image processed by the wavelet transform algorithm was clearer. The positive detection rate of norovirus in children with clinical diarrhea was as high as 59%, and the children had different degrees of body damage, of which the probability of compensatory metabolic acidosis was the highest. The epidemiological analysis found that children with norovirus infection were mainly concentrated in the age group under 2 years old and over 5 years old and showed a peak of infection in December. In summary, the intelligent algorithm based on wavelet transform can realize the noise reduction of intestinal ultrasound, and it should protect children with susceptible age and susceptible seasons to reduce the clinical infection rate of norovirus.

Development and validation of a CT‐based radiomics signature for identifying high‐risk neuroblastomas under the revised Children's Oncology Group classification system

“…Wavelet decomposition is a local transform of space and frequency, allowing for the effective extraction of information from signals. The image signal is decomposed into different sub‐bands by wavelet transform, and different algorithms are applied to enhance the image components in different frequency ranges, thus emphasizing the degree of detail in different scales 32 . Consequently, wavelet decomposition can provide detailed information about the edges of lesions, which is an invaluable tool for image analysis.…”

New Opportunities and Challenges for Health Professionals in the era of Artificial Intelligence – Review

“…In the case of norovirus infection, the management measures most of which rely more on prevention than treatment, data mining technology based on the wavelet transform AI algorithm was used to identify the at-risk group. Such findings can be implemented to protect patients prone to infection and as a result, reduce the clinical infection rate of the virus [7].…”
