WebApr 12, 2024 · This study used facial images gathered from the Kaggle’s autistic children dataset. This is the only publicly available dataset of its kind; thus, we used it to create the models we proposed. Children aged 2–14 years were included in the dataset, with the majority being between the ages of 2 and 8 years. All of the photos were 2D RGB jpegs. WebApr 14, 2024 · The reason "brute" exists is for two reasons: (1) brute force is faster for small datasets, and (2) it's a simpler algorithm and therefore useful for testing. You can confirm that the algorithms are directly compared to each other in the sklearn unit tests. – jakevdp. Jan 31, 2024 at 14:17. Add a comment.
