Unraveling Human Reward Learning: A Hybrid Approach Combining Reinforcement Learning with Advanced Memory Architectures
Practical Solutions and Value
Recent research suggests that human reward learning is more complex than traditional reinforcement learning (RL) models can capture. By combining RL models with artificial neural networks (ANNs), particularly recurrent neural networks (RNNs), a more comprehensive understanding of human decision-making and memory mechanisms is achieved.
By gathering data from a reward-learning task involving 862 participants and over 600,000 trials, the study demonstrated that hybrid models, especially those incorporating RNNs, outperform basic RL models in capturing human decision-making patterns.
The study also reveals that a novel model, Memory-ANN, which incorporates recurrent memory representations, matches the performance of the best RL model, suggesting that detailed memory use is crucial to participants’ learning in the task.
The proposed modular cognitive architecture, Memory-ANN, separates reward-based learning from action-based learning, providing a clearer understanding of how learning influences choices. This dual-layer system allows for flexible, context-driven decision-making, reflecting the full spectrum of human behavior in learning tasks.
These insights could have broader applications, extending to various learning tasks and cognitive science, and could potentially redefine the way companies work and engage with customers by leveraging AI to identify automation opportunities, define KPIs, select AI solutions, and implement AI gradually.
