Natural Language Processing and Recommendation Engine for Stack Overflow Data
… of document retrieval (TF-IDF and HOTT), text embedding (Sentence BERT), and classification (multi-label and multi-class). We experiment with neural networks and other classifier strategies to identify the most relevant Stack Overflow tags. We then use these tags to implement collaborative …

Data-driven Materials Informatics for Optoelectronics: From Natural Language Processing to Predictive Modelling of TADF Molecules
… They are also fine-tuned to perform tasks of text-classification, question-answering, and text embedding. Chapter 5 details an end-to-end workflow that produces a data-driven predictor for the PL wavelengths of organic TADF molecules using molecular SMILES strings as its input. The workflow …

Unsupervised learning of cross-modal mappings between speech and text
… for training acoustic models, collections of text for training language models, and (possibly) linguist-crafted lexicons mapping words to their pronunciations. The immense cost of collecting these resources makes applying state-of-the-art speech recognition algorithm to under-resourced …

Transfer Learning For Spoken Language Processing
… we tackle domain adaptation in the context of Automatic Speech Recognition (ASR) and Cross-Lingual Learning in Automatic Speech Translation (AST). The first part of the thesis develops an algorithm for unsupervised domain adaptation of End-to-End ASR models. In recent years, ASR …

An image-text model for effective retrieval of seventeenth-century Spanish American notary records
… thesis, we investigate the potential of an image-text model that captures the semantic similarities between image and text pairs, for effective retrieval of documents in the seventeenth-century Spanish American notary records containing diverse writing styles. We propose a new technique using …

A MULTILEVEL EXPLORATION OF SCIENCE DYNAMICS WITH COMPUTATIONAL AND QUANTITATIVE TECHNIQUES.
Sebbene le società contemporanee facciano sempre più affidamento sulla scienza, la nostra comprensione di come funziona esattamente la comunità scientifica è ancora limitata. Il lavoro di ricerca ha subito enormi cambiamenti negli ultimi decenni ed è ancora in evoluzione sia come risultato di …
