Bridging the hole: Mind-inspired options to handle catastrophic forgetting in synthetic neural networks

Reminiscence is crucial for our existence and identification. The objective of studying is to have the reminiscence saved within the mind for speedy or intuitive retrievals as wanted. It applies to every part we do in on a regular basis life, resembling expertise, habits, reasoning, social interactions, and decision-making. Whereas we always be taught since start, many want we may have realized sooner and remembered extra. In actuality, we complain ceaselessly about forgetting, whereas, typically, we can not take away the dangerous reminiscences we need to neglect. As we get older, dementia turns into one of many high considerations that will have an effect on our lives and people round us.

Whereas synthetic intelligence (AI) has taken inspiration from human brains and made outstanding advances in deep studying, one problem synthetic neural networks (ANNs) have skilled is catastrophic forgetting, the place the community encounters a sudden and drastic efficiency drop in beforehand mastered duties when studying new data. Catastrophic forgetting usually occurs when an ANN is skilled to be taught a number of duties sequentially. Nonetheless, people can be taught massive numbers of duties all through their lifetime with out forgetting these beforehand realized.

Earlier than delving into AI and catastrophic forgetting, we are going to first look at how the human mind acquires and holds reminiscences by specializing in three key features:

1. Declarative and non-declarative reminiscence with temporal time gradients: The temporal features of declarative and non-declarative reminiscence present perception into how the human mind organizes data over time.
2. Extremely regulated and selective nature of human reminiscence: Human reminiscence displays a excessive diploma of regulation and selectivity, influencing the retention and retrieval of data.
3. Reminiscence consolidation by means of replays throughout sleep: Reminiscence consolidation by means of replays throughout sleep sheds mild on the processes that strengthen and solidify reminiscences.

Given the complexity of the mind mechanisms to make sure remembering and studying in parallel with out inference from one another, we are going to higher perceive the potential gaps…
