("A Faster Algorithm Computing String Edit Distances"). This method splits the matrix in blocks of size t x t. Each possible block is precomputed to produce a lookup table. This lookup table can then be used to compute the string similarity (or distance) in O(nm/t). Usually, t is ...
For cosine similarity, the traditional LSH algorithm used is Random Projection, but others exist, like Super-Bit, that deliver better results.LSH functions have two main use cases:Compute the signature of large input vectors. These signatures can be used to quickly estimate the similarity between ...
A lot of work has been done in the field to detect plagiarism in the documents and algorithms have been made. In this paper, we have implemented porter algorithm for stemming, TF-IDF and cosine similarity to detect plagiarismAttinderpal Singh...
