Hinton. “Visualizing High-Dimensional Data Using t-SNE.” Webscanpy.external.pp.bbknn. Batch balanced kNN [Polanski19]. Batch balanced kNN alters the kNN procedure to identify each cell’s top neighbours in each batch separately instead of the entire cell pool with no accounting for batch. The nearest neighbours for each batch are then merged to create a final list of neighbours for the cell.

WebSetting it to 0.0 means using the “exact” method which would run O (N^2) time, otherwise TSNE would employ Barnes-Hut approximation hich would run O (NlogN). This value is a tradeoff between accuracy and training speed for Barnes-Hut approximation. The training speed would be faster with higher value.
