  The human brain constantly learns and rapidly adapts to new situations by
integrating acquired knowledge and experiences into memory. Developing this
capability in machine learning models is considered an important goal of AI
research since deep neural networks perform poorly when there is limited data
or when they need to adapt quickly to new unseen tasks. Meta-learning models
are proposed to facilitate quick learning in low-data regimes by employing
absorbed information from the past. Although some models have recently been
introduced that reached high-performance levels, they are not biologically
plausible. We have proposed a bio-plausible meta-learning model inspired by the
hippocampus and the prefrontal cortex using spiking neural networks with a
reward-based learning system. Our proposed model includes a memory designed to
prevent catastrophic forgetting, a phenomenon that occurs when meta-learning
models forget what they have learned as soon as the new task begins. Also, our
new model can easily be applied to spike-based neuromorphic devices and enables
fast learning in neuromorphic hardware. The final analysis will discuss the
implications and predictions of the model for solving few-shot classification
tasks. In solving these tasks, our model has demonstrated the ability to
compete with the existing state-of-the-art meta-learning techniques.
