Speaker bio

I completed my studies in electronic engineering at the University of Pretoria and immediately ventured into the field of speech technologies, specialising in text-to-speech (TTS). With over 15 years of expertise as an accomplished C developer, I have successfully executed the development of portable medium to large-scale projects. My proficiency extends to interfacing low-level C libraries with both interpreted and compiled languages. I possess hands-on experience in implementing various machine learning techniques, ranging from traditional pattern recognition to cutting-edge deep learning, in both research and commercial systems. Additionally, I have extensive knowledge in the application of digital signal processing within commercial-grade software. Throughout my career, I have effectively led small, diverse teams consisting of highly skilled researchers and developers, driving them towards shared objectives. I am the principal architect and engineer behind the Qfrency text-to-speech system, which marks a significant milestone as the first commercial-grade TTS engine capable of synthesising text in all 11 official South African languages. The successful commercialisation of the Qfrency TTS system has facilitated its widespread adoption across various sectors, both domestically and internationally. Notable fields of implementation include education, assistive technologies, call centres, and more.

Talk description

We are increasingly living in a world that is characterised by the merger and fusing of the digital and physical realms. ChatGPTs recent massive adoption attests to this. Exactly what this merged reality entails is not clear yet, but there is agreement that almost all aspects of our lives are being affected, either directly or indirectly. Recently some notable Computing scholars described the digital-first observation, which is formally defined as an ontological reversal of the digital and physical worlds [1, 2]. More simply described it is the observation that the physical world preceded the digital world before, but we now observe that the digital world precedes (and often prescribes) the physical world. Anybody that traveled recently would have noticed that our biometric-enhanced virtual identity now precedes any physical document - a physical passport is only used for verification and not primarily for identification.  Several more examples of this digital-first reversal can be observed daily if we care to take notice, including that some of the key objects necessary for learning such as books, music, and videos, now exist primarily and firstly in the digital world before they are being realized into physical existence, and then only when it is necessary for human interaction. This presentation will firstly explore the characteristics of digital objects that inevitably resulted in the digital-first world, followed by a discussion of what digital-first means for us. Lastly, some implications and guidelines are proposed for digital literacy living in this new digital-first world.

Bayesian inference allows us to calculate the posterior distribution of unknown variables given observations, using Bayes’ Theorem. In practice however, it is typically the case that this posterior distribution is intractable to compute exactly. This tutorial introduces variational inference (VI) - which constructs an approximate posterior by framing the inference problem as an optimization problem. As part of this tutorial, we will consider tools such as Pyro which help simplify the application of VI and allow it to scale to large datasets and models. The tutorial concludes by considering an example application of VI in deep learning - Variational Autoencoders.

Talk description

We propose a visually grounded speech model that learns new words and their visual depictions from just a few word- image example pairs. Given a set of test images and a spoken query, we ask the model which image depicts the query word. Previous work has simplified this few-shot learning problem by either using an artificial setting with digit word-image pairs or by using a large number of examples per class. Moreover, all previous studies were performed using English speech-image data. We propose an approach that can work on natural word-image pairs but with less examples, i.e. fewer shots, and then illustrate how this approach can be applied for multimodal few-shot learning in a real low-resource language, Yoruba. Our approach involves using the given word-image example pairs to mine new unsupervised word-image training pairs from large collections of unlabelled speech and images. Additionally, we use a word-to-image attention mechanism to determine word-image similarity. With this new model, we achieve better performance with fewer shots than previous approaches on an existing English benchmark. Many of this model’s mistakes are due to relating a few-shot class with its contextual information. We apply multimodal few-shot learning, for the first time, on an actual low-resource language, Yoruba. By initialising the multimodal Yoruba few-shot model on a larger set of English speech-image data, it can outperform its purely English variant.

Voice conversion aims to transform speech into a target voice with just a few example recordings of the target speaker. Recent methods produce convincing conversions, but at the cost of increased complexity – making results difficult to reproduce and build on. Instead, in this talk I will go over some of our lab’s recent research to keep voice conversion simple by using just the plain k-nearest neighbours algorithm. Despite its simplicity, our recent research is competitive with the largest and complex existing models. I’ll also show how it can be used to perform diverse combinations of conversions, such as converting cross-lingually, or between human and animal sounds.

Arthur C. Clarke once said, ‘Any sufficiently advanced technology is indistinguishable from magic’. One could argue that data scientists are modern magicians… but are we really? The role of a data scientist in industry spans from understanding business context and identifying problems to solve, to thinking of meaningful metrics and explaining solutions to stakeholders. If you are a grad wondering what data science in the real world looks like, this talk is for you.

Talk description

If you’ve ever taken a statistics class, I have little doubt you’ve heard someone say “correlation does not imply causation”. This trope seems to imply that we can never state that A causes B by analysis of data alone. This talk will take a deeper look at if this is always the case by introducing the field of causal inference, with a special focus on (graphical) causal modelling. Attendees will leave having gained knowledge of how assumptions and data come together to enable drawing causal conclusions from data. More importantly, they will develop the basic intuition and fundamental concepts of causal modelling in the context of machine learning.

Speaker bio

St John is incoming PhD candidate at The University of Cape Town, where his research focus is in the area of reinforcement learning and learning agents. His masters thesis investigated the causal methods in the context of reinforcement learning. This led to an interest in how causality can aid in helping solve various problems faced in adaptive learning methods. He also has an academic interest in neuro-plausible methods and multi-agent scenarios, with a strong interest in the emerging field of active inference.
