A Neuro-Dynamic Mathematical Model of Dream Formation and Spontaneous Cognitive Activity

This paper introduces a biomathematical model designed to describe the internal dynamics of dream formation and spontaneous cognitive processes. The model incorporates neurocognitive factors such as dissatisfaction, acceptance, forgetting, and mental activity, each of which is linked to established neural systems. We formulate a system of differential equations to simulate interactions among these variables and validate the model using simulated neural data. Our results demonstrate biologically plausible cognitive patterns consistent with findings from EEG and fMRI studies, particularly related to the default mode network (DMN), anterior cingulate cortex (ACC), and hippocampal memory mechanisms.

Enhancing PAC Learning of Half spaces Through Robust Optimization Techniques

This paper explores the challenges of PAC learning in semi-enclosed environments that face persistent disruptive noise and demonstrates the weaknesses of traditional learning models based on noise-free data. We present a novel algorithm that enhances noise robustness in semiconservative learning by using robust optimization techniques and advanced error correction methods and improves learning accuracy without adding additional computational cost. We also prove that this algorithm is very resistant to hostile noises. Experimental results on various datasets demonstrate its effectiveness. They provide a scalable solution for increasing the reliability of machine learning in noisy environments which contributes to noise-resilient learning and increased confidence in ML applications.
