Radiation Oncology/Artificial neural network

A recent survey of AI applications in health care reported uses in major disease areas such as cancer or cardiology and artificial neural networks (ANN) as a common machine learning technique

Applications of ANN in health care include clinical diagnosis, prediction of cancer, speech recognition, prediction of length of stay, image analysis and interpretation (e.g. automated electrocardiographic (ECG) interpretation used to diagnose myocardial infarction), and drug development

Non-clinical applications have included improvement of health care organizational management, prediction of key indicators such as cost or facility utilization

ANN has been used as part of decision support models to provide health care providers and the health care system with cost-effective solutions to time and resource management

Most important types of neural networks that form the basis for most pre-trained models in deep learning:

Multi-institutional, 2023 PMID 36929393 Skyler B Johnson et al. "Using ChatGPT to evaluate cancer myths and misconceptions: artificial intelligence and cancer information"
- Following expert review, the percentage of overall agreement for accuracy was 100% for NCI answers and 96.9% for ChatGPT outputs for questions 1 through 13 (ĸ = ‒0.03, standard error = 0.08)
- There were few noticeable differences in the number of words or the readability of the answers from NCI or ChatGPT
- Overall, the results suggest that ChatGPT provides accurate information about common cancer myths and misconceptions
