Researchers explored the lottery ticket hypothesis, which suggests that sparse subnetworks within dense neural networks can achieve similar performance to the full model. They used a simplified toy model with a structured feature space to investigate what these "winning tickets" preserve. Their findings indicate that these tickets correspond to specific locations in the feature space that are already close to the final learned representations at initialization, with dense training acting as a selection process.
