In recent years, reinforcement learning (RL) has achieved a remarkable achievement and it attracted researchers' attention in modeling real-life scenarios by expanding its research beyond conventional complex games. Prediction of optimal treatment regimens from observational real clinical data is being popularized, more advanced versions RL algorithms are implemented the literature. However, RL-generated medications still need careful supervision expertise parties or doctors healthcare....

SplitFed Learning, a combination of Federated and Split Learning (FL SL), is one the most recent developments in decentralized machine learning domain. In learning, model trained by clients server collaboratively. For image segmentation, labels are created at each client independently and, therefore, subject to clients' bias, inaccuracies, inconsistencies. this paper, we propose data quality-based adaptive averaging strategy for called QA-SplitFed, cope with variation annotated ground truth...

Text summarization helps in reducing the size of a text while preserving its information content. Summarization can be derived as shortening source to version that it's content and overall meaning is preserved. It very difficult for human beings manually summarize large documents text. These methods classified into two broader such extractive abstractive summarization. The prior method consists selecting important sentences; paragraphs etc. from document make brief it by combining them....

Text summarization is the task of condensing a text segment into shorter version, reducing size original context while also preserving informational elements and meaning content. Manual will involve significant amount time thus become expensive generally laborious task. Aiming to reduce these pitfalls in manual summarization, automatic has been evolving now bearing strong motivation for academic research. Summarization carried out by two main approaches, namely Extraction Abstraction. This...

Federated Learning (FL) enables multiple clients to train a collaborative model without sharing their local data. Split (SL) allows be trained in split manner across different locations. Split-Federated (SplitFed) learning is more recent approach that combines the strengths of FL and SL. SplitFed minimizes computational burden by balancing computation servers, while still preserving data privacy. This makes it an ideal framework various domains, especially healthcare, where privacy utmost...
