Written By DataScience+ Program R Project Published Jul 30, 2015 Updated Oct 30, 2017In this post, we will show how to create vectors, factors, lists, matrices and datasets in R Vectors The vector is a very important tool in R programming. Through vectors, we create matrix and data...
Vector Storage is a vector database that enables semantic similarity searches on text documents in the browser's local storage. It uses OpenAI embeddings to convert documents into vectors and allows searching for similar documents based on cosine similarity. ...
Simultaneous developments in big data, social media, and computational social science have set the stage for how we think about and understand interpersonal and mass communication. This article explores some of the ways that these developments generate 4 hypothetical 'vectors'-directions-into the next...
