The answers to these questions are always changing, but that’s what keeps work with the DELTA Lab so engaging!
Tsun Lok Kwan, Class of 2021
Tsun worked on extracting, clustering and visualizing near-duplicate tokenized news stories from massive corpora obtained from Sinclair-owned television stations. Locality-sensitive hashing algorithms were used for collision-maximizing approximate nearest neighbor search to drastically reduce search space. The Smith-Waterman algorithm was adapted from protein sequencing to assess text similarity for NLP. LDA topic modelling was used to probabilistically derive unobserved groupings to cluster tokenized news broadcasts. t-SNE dimensionality reduction was used to compute the optimal embedding of high dimensional vectorized text in low dimensional space to accurately visualize topic clusters and finally wavelet image hashing and image histograms were used to efficiently extract and classify political advertisements
