1. 6. Incremental Re-tokenization in BPE-trained SentencePiece Models

   Kandidat-uppsats, Umeå universitet/Institutionen för datavetenskap

   Författare :Simon Hellsten; [2024]
   Nyckelord :BPE; Byte Pair Encoding; SentencePiece; NLP; Natural Language Processing; Tokenization; Re-tokenization;

   Sammanfattning : This bachelor's thesis in Computer Science explores the efficiency of an incremental re-tokenization algorithm in the context of BPE-trained SentencePiece models used in natural language processing. The thesis begins by underscoring the critical role of tokenization in NLP, particularly highlighting the complexities introduced by modifications in tokenized text. LÄS MER

3. 7. A type-driven approach for sensitivity checking with branching

   Master-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

   Författare :Daniel Freiermuth; [2023-10-24]
   Nyckelord :Computer; science; computer science; thesis; differential privacy; type system; sensitivity; branching;

   Sammanfattning : Differential Privacy (DP) is a promising approach to allow privacy preserving statistics over large datasets of sensitive data. It works by adding random noise to the result of the analytics. Understanding the sensitivity of a query is key to add the right amount of noise capable of protecting privacy of individuals in the dataset. LÄS MER

4. 8. Ensuring the Security of PyPI Packages

   Master-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

   Författare :David Shakoori Gustafsson; [2023-10-23]
   Nyckelord :Computer science; Security; Python; PyPI; Typosquatting;

   Sammanfattning : Developers often use open-source code libraries in order to achieve desired functionalities without needing to re-implement existing code. Python developers are no exceptions here, and frequently use the Python Package Index, PyPI, to download the specific code packages they want to use. LÄS MER
