In this episode of Simply Science, we explore the fascinating parallels between the brain's memory system and artificial intelligence. The brain acts as an information filter, much like a computer clearing disk spaceâit deletes outdated or irrelevant data to make room for new insights. This process, known as âcatastrophic forgettingâ in neuroscience, involves the weakening or resetting of neural connections, allowing the brain to rewire itself and adapt. While this may seem like a flaw, itâs a feature that enhances flexibility, helps us let go of negative experiences, and improves decision-making in dynamic environments.
For artificial intelligence, forgetting is just as essential. To achieve artificial general intelligence, AI systems must learn, adapt, and selectively forget outdated information. This ability prevents overfitting, enhances algorithm generalization, and enables AI to tackle real-world problems effectively.
Join us as we dive into how selective forgetting, both in humans and machines, holds the key to adaptability, better learning, and the pursuit of artificial general intelligence. If youâve ever wondered why forgetting is just as important as remembering, this episode is for you!

Drawing on pioneering works in time-series causality, we explore how integrating causal reasoning, principles of statistical physics, and brain-inspired cognitive activities could transform AI, enhancing its ability to generalize in unpredictable environments.
This episode sheds light on the exciting challenges and breakthroughs at the intersection of neuroscience, physics, and artificial intelligence. Whether youâre an AI enthusiast, a science lover, or just curious about the future of machine learning, this is an episode you wonât want to miss!

In this episode of Simply Science, we explore a fascinating new approach to machine learning inspired by how our brain works. Imagine using a system of elements that can switch between two states, like light switches being on or off. These elements are influenced by random noise, just like neurons firing unpredictably. Instead of relying on exact values, this system stores information in patterns of probabilities.
The researchers show how this method can solve the XOR problem, which is important for creating complex machine-learning systems. Their findings suggest this approach could be useful for applications that need to be both energy-efficient and resilient to noise.
