Fast Approximation of Similarity Graphs with Kernel Density Estimation He Sun School of Informatics School of Informatics University of Edinburgh University of Edinburgh United Kingdom

Neural Information Processing Systems

However, typical constructions of a similarity graph have high time complexity, and a quadratic space dependency with respect to |X|. We address this limitation and present a new algorithmic framework that constructs a sparse approximation of the fully connected similarity graph while preserving its cluster structure. Our presented algorithm is based on the kernel density estimation problem, and is applicable for arbitrary kernel functions. We compare our designed algorithm with the well-known implementations from the scikit-learn library and the FAISS library, and find that our method significantly outperforms the implementation from both libraries on a variety of datasets.

Representation Learning for Words and Entities

arXiv.org Artificial Intelligence

This thesis presents new methods for unsupervised learning of distributed representations of words and entities from text and knowledge bases. The first algorithm presented in the thesis is a multi-view algorithm for learning representations of words called Multiview Latent Semantic Analysis (MVLSA). By incorporating up to 46 different types of co-occurrence statistics for the same vocabulary of english words, I show that MVLSA outperforms other state-of-the-art word embedding models. Next, I focus on learning entity representations for search and recommendation and present the second method of this thesis, Neural Variational Set Expansion (NVSE). NVSE is also an unsupervised learning method, but it is based on the Variational Autoencoder framework. Evaluations with human annotators show that NVSE can facilitate better search and recommendation of information gathered from noisy, automatic annotation of unstructured natural language corpora. Finally, I move from unstructured data and focus on structured knowledge graphs. I present novel approaches for learning embeddings of vertices and edges in a knowledge graph that obey logical constraints.


Amazon built an AI tool to hire people but had to shut it down because it was discriminating against women

#artificialintelligence

Amazon worked on building an artificial-intelligence tool to help with hiring, but the plans backfired when the company discovered the system discriminated against women, Reuters reports. Citing five sources, Reuters said Amazon set up an engineering team in Edinburgh, Scotland, in 2014 to find a way to automate its recruitment. The company created 500 computer models to trawl through past candidates' rรฉsumรฉs and pick up on about 50,000 key terms. The system would crawl the web to recommend candidates. "They literally wanted it to be an engine where I'm going to give you 100 rรฉsumรฉs, it will spit out the top five, and we'll hire those," one source told Reuters.
