Four word embedding models implemented in Python. Supporting arbitrary context features

🧮 Python package to construct word embeddings for small data using PMI and SVD

Analysis of Parkinson's Progressive Markers Initiative Data

An implementation of (Chambers and Jurafsky, 2008), using updated machine learning models, and different training data domains for an independent study at the University of Pennsylvania.

In this paper we compare and evaluate two simple embedding models which can be constructed directly from a given co-occurrence matrix extracted from Twitter data; Positive Pointwise Mutual Information (PPMI), and Hellinger Principal Component Analysis (H-PCA). For each embedding model we consider three alternative metrics for word similarity: co…

Parkinson's Progression Marker Initiative data science challenge, 2016

The project strives to predict the risk of Parkinson's Disease progression in the patient based on the evaluation of baseline motor and non-motor symptoms of the patients via machine learning approach.

Construct Word Embeddings with PPMI & SVD

In this assignment I will explore different kind of encoding techniques such as co-occurrence matrix, sparse representations via PPMI weighting, pre-trained dense word embeddings, ecc...

This repository contains two implementations of an NLP document query system that processes PDF documents and ranks them based on relevance to user queries.

Análise empírica de acórdãos do STF sobre desinformação e os atos antidemocráticos de 8 de janeiro de 2023: pipeline reprodutível com MCDA/WSM, BM25, TF-IDF/cosseno, seleção estratificada, nuvem de palavras e heatmap PPMI.

Turn documents into vectors by decomposing a PPMI cooccurence matrix.

My thesis work. Data processing on Google Drive. Here are only scripts and key findings.

This project focuses on text mining "The Big Bang Theory" scripts, covering 10 seasons. Participants preprocess character dialogues, analyzing sentence/word counts, noun/person name mentions, important words per episode/season, and word co-occurrence. (Part of Evaluation of Text Mining-KUL [G00C8a])
