Not What the Doctor Ordered: Surveying LLM-based De-identification and Quantifying Clinical Information Loss

De-identification in the healthcare setting is an application of NLP where automated algorithms are used to remove personally identifying information of patients (and, sometimes, providers). With the recent rise of generative large language models (LLMs), there has been a corresponding rise in the number of papers that apply LLMs to de-identification. Although these approaches often report near-perfect results, significant challenges concerning reproducibility and utility of the research papers persist. This paper identifies three key limitations in the current literature: inconsistent reporting metrics hindering direct comparisons, the inadequacy of traditional classification metrics in capturing errors which LLMs may be more prone to (i.e., altering clinically relevant information), and lack of manual validation of automated metrics which aim to quantify these errors. To address these issues, we first present a survey of LLM-based de-identification research, highlighting the heterogeneity in reporting standards. Second, we evaluated a diverse set of models to quantify the extent of inappropriate removal of clinical information. Next, we conduct a manual validation of an existing evaluation metric to measure the removal of clinical information, employing clinical experts to assess their efficacy. We highlight poor performance and describe the inherent limitations of such metrics in identifying clinically significant changes. Lastly, we propose a novel methodology for the detection of clinically relevant information removal.

AIOptimizer -- A reinforcement learning-based software performance optimisation prototype for cost minimisation

This research article introduces AIOptimizer, a prototype for a software performance optimisation tool based on cost reduction. AIOptimizer uses a recommendation system driven by reinforcement learning to improve software system efficiency and affordability. The paper highlights AIOptimizer's design factors, such as accuracy, adaptability, scalability, and user-friendliness. To provide effective and user-centric performance optimisation solutions, it emphasises the use of a modular design, data gathering techniques, continuous learning, and resilient integration. The article also investigates AIOptimizer features such as fault identification, cost optimisation recommendations, efficiency prediction, and cooperation. Furthermore, it explores several software development life cycle models and introduces AIOptimizer uses a reinforcement learning-based recommendation engine for cost optimisation. The purpose of this research study is to highlight AIOptimizer as a prototype that uses advanced optimisation techniques and smart recommendation systems to continually enhance software performance and save expenses. The research focuses on various software development life cycle models, such as the Waterfall model, Iterative model, Spiral model, V-Model, Big Bang model and Agile Model. Each model has advantages and disadvantages, and their usefulness is determined by the project's specifications and characteristics. The AIOptimizer tool is a theoretical prototype for such software performance optimizers.

Incorporating Deep Q -- Network with Multiclass Classification Algorithms

In this study, we explore how Deep Q-Network (DQN) might improve the functionality of multiclass classification algorithms. We will use a benchmark dataset from Kaggle to create a framework incorporating DQN with existing supervised multiclass classification algorithms. The findings of this study will bring insight into how deep reinforcement learning strategies may be used to increase multiclass classification accuracy. They have been used in a number of fields, including image recognition, natural language processing, and bioinformatics. This study is focused on the prediction of financial distress in companies in addition to the wider application of Deep Q-Network in multiclass classification. Identifying businesses that are likely to experience financial distress is a crucial task in the fields of finance and risk management. Whenever a business experiences serious challenges keeping its operations going and meeting its financial responsibilities, it is said to be in financial distress. It commonly happens when a company has a sharp and sustained recession in profitability, cash flow issues, or an unsustainable level of debt.
