Student Awards

2018 winners

2017/2018 SASA Honours Project Competition Sponsored by SAS®

It is the SASA Education Committee’s pleasure to announce the winners of the 2017/2018 SASA Honours Project Competition. We received 19 honours projects from 8 universities this year. Thank you to Nelson Mandela University (NMU), Stellenbosch University (SU), University of Cape Town (UCT), University of Fort Hare (UFH), University of KwaZulu-Natal (UKZN), University of Pretoria (UP), University of the Witwatersrand (Wits), and University of Venda (UNIVEN) for their entries. Congratulations to the following entries:

First Prize

The Classification of Galaxy Images Using Convolutional Neural Networks

James Lloyd (UCT)

(R8000 + Sponsorship to attend and present the project at SASA2018)

Second Prize

Sampling from Distributions Using Genetic Algorithms

Sibusiso Thabene (UCT)

(R5500)

Third Prize

CLARA Algorithm for Image Clustering

Mark de Lancey (UP)

(R4000 + Special prize of R2000 for best use of SAS)

In fourth place, there was the project “An Empirical Study to Classify the Daily Movement of Naspers Ltd.’s Share Price: A Comparison of Statistical Learning Techniques” by Ian Louw & Tristan Naidoo (SU). There was also a special prize for the project that made the best use of SAS and is ranked in the top 3. This year it is awarded to the Third Price Winner.

The SASA Education Committee is grateful to the following judges for their time and effort: Prof Legesse Debusho (UNISA), Prof Carl Lombard (MRC), Porf Shaun Ramroop (UKZN), Dr Victoria Goodall (NMU), Dr Justin Harvey (SU), and Dr Vince Micali (Stats4Buz). As always, ranking the top projects was a difficult task, in particular due to the variety of standards and subject areas, and the number of projects that had to be adjudicated.  We’d also like to extend a special word of thanks to SAS for their continued support of this competition. 

Congratulations to all the winners!
