Deep dives
Challenges of AI Learning
Deep learning AIs struggle to adapt when faced with new data, leading to a phenomenon referred to as 'loss of plasticity.' As these systems are trained, their neural connections become rigid, causing them to forget previously learned information when presented with new tasks. Researchers found that if a model learns to differentiate between certain classes of animals, it may entirely lose the ability to learn about new classes when tasked with them repeatedly. This poses a significant challenge for AI deployment in dynamic real-world environments where continuous learning is crucial.
