First, the full set of experimental data (from flies) is used to compute a Gaussian kernel density estimator (KDE). To quantify the similarity (to data) of a given bout of simulated walking, we apply the KDE to evaluate the log probability density function of each bout, a scalar value we refer to as kinematic similarity (KS). High KS indicates that the perturbed walking resembles the unperturbed walking from data, while low KS indicates that the perturbed walking deviates from data.", "blurhash": "U8RW3j~W%14.s;xZRjx]%2bGofoM%fD*-;IT", "width": 763, "height": 350 } ], "tag": [], "replies": { "id": "https://synapse.cafe/users/lili/statuses/112321913987339551/replies", "type": "Collection", "first": { "type": "CollectionPage", "next": "https://synapse.cafe/users/lili/statuses/112321913987339551/replies?min_id=112321920332758995&page=true", "partOf": "https://synapse.cafe/users/lili/statuses/112321913987339551/replies", "items": [ "https://synapse.cafe/users/lili/statuses/112321920332758995" ] } } } ] } }
