INTRODUCTION Atypical antipsychotics are essential in managing various psychiatric disorders but associated with significant cardiometabolic side effects, including weight gain, insulin resistance, and dyslipidemia. These adverse effects increase the risk of metabolic syndrome cardiovascular diseases patients undergoing long-term antipsychotic therapy. Understanding underlying mechanisms, such as alterations appetite regulation, glucose, lipid metabolism, is crucial for developing effective...
The deployment of Deep Learning models requires attention to certain aspects not typically considered during the training phase. One these is identifying and labeling samples from unknown classes. This goal out-of-distribution (OOD) detection, which enhances robustness in open-world scenarios. There are numerous methods for addressing this problem, using different feature spaces distinguish between in-distribution OOD data. such method Open Principal Component Score (OpenPCS), a technique...
