Topic: maximally exciting stimuli

While several methods exist for clustering neurons based on their selectivity to specific visual features, the extent to which neurons form clusters based on their invariances - how neurons maintain consistent responses despite variations in visual input - remains largely unexplored. Clustering neurons based on their invariances, however, presents several challenges, including the identification of directions in the stimulus space along which a neuron exhibits invariance (i.e., consistent response), and the comparison and alignment of such non-trivial trajectories to assess whether neurons exh
