  1. 1. Low Supervision, Low Corpus size, Low Similarity! Challenges in cross-lingual alignment of word embeddings : An exploration of the limitations of cross-lingual word embedding alignment in truly low resource scenarios

    University essay from Uppsala universitet/Institutionen för lingvistik och filologi

    Author : Andrew Dyer; [2019]
    Keywords : word embeddings; cross-lingual; multilingual; low-resource; corpus size; Vecmap; FastText; alignment; orthogonal; eigenvalues; Laplacian; isospectral; isomorphic; bilingual lexicon induction;

    Abstract : Cross-lingual word embeddings are an increasingly important reseource in cross-lingual methods for NLP, particularly for their role in transfer learning and unsupervised machine translation, purportedly opening up the opportunity for NLP applications for low-resource languages.  However, most research in this area implicitly expects the availablility of vast monolingual corpora for training embeddings, a scenario which is not realistic for many of the world's languages.

  2. 2. Supersymmetric Quantum Mechanics

    University essay from Lunds universitet/Teoretisk partikelfysik; Lunds universitet/Institutionen för astronomi och teoretisk fysik

    Author : Johan Gudmundsson; [2014]
    Keywords : bachelor thesis; Supersymmetric Quantum Mechanics; Quantum Mechanics; Physics and Astronomy;

    Abstract : This bachelor thesis contains an introduction into supersymmetric quantum mechanics(SUSYQM). SUSYQM provides a different way of solving quantum mechanical problems. The thesis explains the basic concepts of SUSYQM, such as the factorization of a Hamiltonian, the definition of its superpotential and the shape invariant potentials. READ MORE
