Nvidia researchers detail AI-powered clinical speech transcription system

At the Conference for Machine Intelligence in Medical Imaging 2020, which was held practically this yr, Nvidia researchers launched a paper describing an AI system that captures and transcribes scientific victims’ speech. The system identifies scientific phrases and maps the phrases in a standardized effectively being database, duties the researchers say would possibly alleviate pressure on clinicians as they experience pandemic-related overwork.

The coauthors counsel telemedicine as one potential use of the system, a self-discipline that has seen unprecedented demand all through the coronavirus pandemic. In March, virtual health consultations grew by 50%, in accordance with Frost and Sullivan evaluation, with primary on-line medical visits on monitor to hit 200 million this yr.

At the core of the researchers’ system is a BERT-based language model pretrained in a self-supervised methodology on a textual content material info set. (Self-supervised finding out is a means of teaching fashions to hold out duties with out providing labeled info.) Bio-Megatron, a model with 345 million parameters — configuration variables inside to the model — ingested and realized patterns from 6.1 billion phrases extracted from PubMed, a search engine for abstracts on life sciences issues.

After pretraining, the model was fine-tuned on a scientific pure language processing info set created by a former National Institutes of Health (NIH)-funded National Center for Biomedical Computing agreement. Then, it was included into an computerized speech recognition ingredient that performs phrase identification and checks phrases in opposition to concepts inside the Unified Medical Language System (UMLS), an ontology developed by the NIH’s National Library of Medicine.

In experiments engaged on Nvidia V100 and T4 graphics enjoying playing cards, the researchers report that Bio-Megatron achieved 92.05% accuracy after 1 millisecond of processing when bearing in mind precision and recall. “This opens significant new capabilities in systems where responsiveness to patients, clinicians, and researchers is paramount … An automatic speech recognition model that can extract and relate key clinical concepts from clinical conversations can be very useful,” they wrote. “We hope our contribution will help achieve faster and better patient responses, ultimately leading to improved patient care.”

Nvidia’s contribution to the evaluation neighborhood comes after Microsoft coauthors proposed a ‘state-of-the-art’ biomedical language model dubbed PubMedBERT. They claimed they managed industry-leading outcomes on duties along with named entity recognition, evidence-based medical information extraction, doc classification, and further.
