Linguistic theory visualized: Word proximity demo uses PPMI and SVD
This demo illustrates a linguistic theory by visualizing word relationships in a 3D space. It uses Positive Pointwise Mutual Information (PPMI) to quantify how often words appear together more than chance would predict.…

New method improves Random Indexing embeddings with sparse PPMI graph averaging
Researchers have developed a method to improve Random Indexing (RI) embeddings by averaging them with a sparse Positive Pointwise Mutual Information (PPMI) graph. This technique, tested on a fairytales corpus, enhanced …

Sparse PPMI graph averaging boosts Random Indexing embeddings
This paper introduces a method for improving Random Indexing (RI) embeddings by averaging them on a sparse Positive Pointwise Mutual Information (PPMI) graph. The technique showed a significant accuracy increase from 19…
