Nearest neighbor search has become a significant research problem due to its wide applications. Traditional spatial index structures such as R-tree and KD-tree can efficiently return accurate nearest neighbor search results in low-dimensional space. but they are not suitable for high-dimensional space. Locality sensitive B-tree(LSB) hashes data points to the sortable one-dimension val... https://parisnaturalfoodes.shop/product-category/passionflower/
