Motivation is Something You Need

AI Summary

This work proposes a dual-model alternating training paradigm inspired by the SEEKING motivational system in affective neuroscience, aiming to balance model performance, training cost, and deployment constraints. In this framework, a small-scale base model undergoes continuous training, while a larger “motivational” model is activated only intermittently upon predefined triggering conditions. By integrating shared weight updates and selective network expansion, the approach—novel in its incorporation of neuroscientific motivation mechanisms into deep learning—achieves significant gains in both efficiency and accuracy on image classification tasks. The base model outperforms conventionally trained counterparts, and the motivational model surpasses standalone large models using substantially less data, all while reducing overall training costs.

Abstract

This work introduces a novel training paradigm that draws from affective neuroscience. Inspired by the interplay of emotions and cognition in the human brain and more specifically the SEEKING motivational state, we design a dual-model framework where a smaller base model is trained continuously, while a larger motivated model is activated intermittently during predefined"motivation conditions". The framework mimics the emotional state of high curiosity and anticipation of reward in which broader brain regions are recruited to enhance cognitive performance. Exploiting scalable architectures where larger models extend smaller ones, our method enables shared weight updates and selective expansion of network capacity during noteworthy training steps. Empirical evaluation on the image classification task demonstrates that, not only does the alternating training scheme efficiently and effectively enhance the base model compared to a traditional scheme, in some cases, the motivational model also surpasses its standalone counterpart despite seeing less data per epoch. This opens the possibility of simultaneously training two models tailored to different deployment constraints with competitive or superior performance while keeping training cost lower than when training the larger model.
