(English) 2022-07-15 2 pm Group Webinar (Teams): Chanelle Matadah Manfouo, Quantum-Access Security of the Winternitz One-Time Signature Scheme

Teams

Abstract:  Quantum-access security, where an attacker is granted superposition access to secret keyed functionalities, is a fundamental security model and its study has inspired results in post-quantum security. We revisit, and fill a gap in, the quantum-access security analysis of the Lamport one-time signature scheme (OTS) in the quantum random oracle model (QROM) by Alagic …

(English) 2022-08-05 Group Webinar: Martin Canaan Mafunda, A hybrid tweet classification system based on Word2Vec and SVM algorithms

Teams

Abstract: In this study, a hybrid tweet classification system built using Word2Vec and Support Vector Machines is presented. The aim of the study is to use the tweet classification system to solve the natural language processing task of automatically assigning labels to unseen tweets into three label attributes namely, anti-zuma, neutral and pro-zuma. Model building …

(English) Weekly Quantum Group Webinar: Martin Canaan Mafunda, Comparison of machine learning algorithms for automated tweet identification system

Zoom

Comparison of machine learning algorithms for an automated tweet identification system Martin Canaan Mafunda (UKZN) Abstract: In this study, six machine learning algorithms are trained based on 3100 tweets with either pro-Zuma, anti-Zuma or neutral sentiments. The aim of the investigation is to compare the ML algorithm's performance on tweet identification and use the findings …
