Dear Colleagues,
Conventional research covers a limited range of predictors for healthcare applications, using statistical models with an unrealistic assumption of ceteris paribus, i.e., “all the other variables staying constant”. For this reason, emerging literature employs artificial intelligence for healthcare applications. It is free from unrealistic assumptions of “all the other variables staying constant”. It delivers important values and rankings of predictors for healthcare applications (e.g., SHAP plots). Moreover, the notions of generative artificial intelligence and reinforcement learning are enjoying immense popularity now. Given a sequence of words, generative artificial intelligence generates a sequence of their probabilities based on BERT or GPT. Its astonishing performance comes from the attention mechanism (in which different input words receive different weights based on their similarity with the output word). And reinforcement learning is a branch of machine learning in which (1) the environment presents a series of rewards, (2) an agent takes a series of actions to maximize the cumulative reward in response, and (3) the environment moves to the next period with the given transition probabilities. In fact, it has been reinforcement learning that has brought the notion of artificial intelligence to worldwide popularity since the publication of a seminal article on Alpha-Go in 2016. Two revolutionary ideas behind reinforcement learning were that artificial intelligence (e.g., Alpha-Go) starts like a human player, i.e., takes a series of actions and maximizes the cumulative reward (chance of victory) from the limited information available in limited periods only, and that it moves far beyond the best human player ever based on the sheer power of big data covering all human players to date. Little examination has been conducted and more investigation is needed on these important issues. In this context, this Special Issue invites original and review articles on novel approaches for machine learning in healthcare applications.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
