Who Has the Best Prices for Tech’s Top 100 Products of the Year? A Machine Learning Analysis.
If you haven’t read my friend’s post for part 1, please do so as here, we will continue to discuss about the remaining part of the project.Continuation AnalysisWe would like to predict whether each given searched result from iprice will match with one of the top 100 coolest electronic gadgets.The features we considered to be included are:dist_jw : Jaro–Winkler distanceprice_diff_ratio : ( price— refer_price) / refer_pricediscount : Discount percentageJaro-Wrinkler distance“In computer science and statistics, the Jaro-Winkler distance is a string metric for measuring the edit distance between two sequences.Informally, the Jaro distance between two words is the minimum number of single-character transpositions required to change one word into the other.The Jaro-Winkler distance uses a prefix (...)
#textreuse: This #R package provides a set of functions for measuring #similarity among documents and detecting passages which have been reused. It implements shingled #n-gram, skip n-gram, and other tokenizers; similarity/dissimilarity functions; pairwise comparisons; and minhash and locality sensitive hashing algorithms.
