Automated Alzheimer's disease detection using active learning model with reinforcement learning and scope loss function.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Alzheimer's disease (AD) is a chronic, incurable brain disorder, and early detection is essential for effective management. Traditional detection methods often rely on large, pre-labeled image datasets, which are costly and difficult to compile. To address this, we propose an innovative active learning framework that improves model performance using fewer labeled samples. Conventional active learning techniques often use static selection strategies that lack adaptability. To address this, the method combines deep reinforcement learning (DRL) with a scope loss function (SLF) to improve flexibility. This allows a dynamic balance between exploiting known data and exploring new data opportunities. To reduce hyperparameter sensitivity in DRL, we apply an advanced differential evolution (DE) algorithm. The model was evaluated on the OASIS and ADNI datasets, achieving F-measures of 92.044% and 93.685%, showing its superiority in early AD detection.
