WebFeature hashing is a clever way of modeling data sets containing large amounts of factor and character data. It uses less memory and requires little pre-processing. In this walkthrough, we model a large healthcare data set by first using dummy variables and then feature hashing. What’s the big deal? Well, normally, one would: WebJun 9, 2024 · The idea of “feature hashing”: Convert data into a vector of features. This is done using hashing, we call the method “feature hashing” or “the hashing trick”. How it works:
In machine learning, feature hashing, also known as the hashing trick (by analogy to the kernel trick), is a fast and space-efficient way of vectorizing features, i.e. turning arbitrary features into indices in a vector or matrix. It works by applying a hash function to the features and using their hash values as indices … See more Motivating Example In a typical document classification task, the input to the machine learning algorithm (both during learning and classification) is free text. From this, a bag of words (BOW) representation is … See more Implementations of the hashing trick are present in: • Apache Mahout • Gensim See more • Hashing Representations for Machine Learning on John Langford's website • What is the "hashing trick"? - MetaOptimize Q+A See more Feature hashing (Weinberger et al. 2009) The basic feature hashing algorithm presented in (Weinberger et al. 2009) is defined as follows. First, one specifies … See more Ganchev and Dredze showed that in text classification applications with random hash functions and several tens of thousands of … See more • Bloom filter • Count–min sketch • Heaps' law • Locality-sensitive hashing • MinHash See more A good hash function should map the expected inputs as evenly as possible over its output range. That is, every hash value in the output range should be generated with roughly the same probability. The reason for this last requirement is that the cost of hashing-based methods goes up sharply as the number of collisions—pairs of inputs that are mapped to the same hash value—increases. If some hash values are more likely to occur than others, a larger fraction of t…
