Word2vec is a technique in natural language processing (NLP) for obtaining vector representations of words. These vectors capture information about the meaning of the word based on the surrounding words. The word2vec algorithm estimates these representations by modeling text in a large corpus. Once trained, such a model can detect synonymous ...
Bootstrap aggregating, also called bagging (from b ootstrap agg regat ing ), is a machine learning ensemble meta-algorithm designed to improve the stability and accuracy of machine learning algorithms used in statistical classification and regression.
The Vector Institute is a private, non-profit artificial intelligence research institute in Toronto focusing primarily on machine learning and deep learning research. As of 2023, it consists of 143 faculty members and affiliates — 38 of which are CIFAR AI chairs — 57 postdoctoral fellows, and 502 students. [2] Along with the University of Toronto, the Vector Institute is affiliated with ...
Feature hashing. 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. [1] [2] It works by applying a hash function to the features and using their hash values as ...
Bootstrapping (statistics) Bootstrapping is any test or metric that uses random sampling with replacement (e.g. mimicking the sampling process), and falls under the broader class of resampling methods.
The latest University of Michigan consumer sentiment survey released Friday showed sentiment hit its lowest level in seven months during June. The index reading for the month came in at 65.6, down ...
