Abstract Objective To demonstrate enabling multi-institutional training without centralizing or sharing the underlying physical data via federated learning (FL). Materials and Methods Deep models were trained at each participating institution using local clinical data, an additional model was FL across all of institutions. Results We found that exhibited superior performance generalizability to single institutions, with overall level significantly better than any institutional alone when...
Abstract There are enormous enthusiasm and concerns in applying large language models (LLMs) to healthcare. Yet current assumptions based on general-purpose LLMs such as ChatGPT, which not developed for medical use. This study develops a generative clinical LLM, GatorTronGPT, using 277 billion words of text including (1) 82 from 126 departments approximately 2 million patients at the University Florida Health (2) 195 diverse general English text. We train GatorTronGPT GPT-3 architecture with...
Federated learning (FL) allows the collaborative training of AI models without needing to share raw data. This capability makes it especially interesting for healthcare applications where patient and data privacy is utmost concern. However, recent works on inversion deep neural networks from model gradients raised concerns about security FL in preventing leakage In this work, we show that these attacks presented literature are impractical use-cases clients' involves updating Batch...
Federated learning (FL) enables building robust and generalizable AI models by leveraging diverse datasets from multiple collaborators without centralizing the data. We created NVIDIA FLARE as an open-source software development kit (SDK) to make it easier for data scientists use FL in their research real-world applications. The SDK includes solutions state-of-the-art algorithms federated machine approaches, which facilitate workflows distributed across enterprises enable platform developers...
