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 …

On Post-Hoc Dimensionality Reduction of Text Embeddings
Text embeddings are a core representation in modern NLP, supporting tasks such as retrieval, clustering, classification, and semantic search. However, embeddings often have hundreds or thousands of dimensions, creating substantial storage and efficiency challenges at scale. In this work, we present …

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 …
