Welcoming new Lecturer: Bhusan Chettri

We’re pleased to welcome new Lecturer Bhusan Chettri to our group!

Bhusan started a full-time role this month as Lecturer in Data Analytics. He says:

Bhusan Chettri photo“I completed my Ph.D. degree from QMUL in August 2020 under the supervision of Dr. Emmanouil Benetos and Dr. Bob Sturm (who is now at KTH, Sweden). During my Ph.D. studies, I was also working as a part-time Lecturer of Data Analytics at QMUL.

“My Ph.D. research focused on the design and analysis of secure voice biometrics. I look forward to continuing my work on fake audio/speech detection using generative models, representation learning, and adversarial attacks. Furthermore, I am also keen to explore interpretability for voice biometrics and anti-spoofing systems.”

Honorary Lectureship for Helen Bear

We’re pleased to announce that Helen Bear (Yogi), who has been working with us since 2018, has been awarded a QMUL Honorary Lectureship for 3 years.

Yogi says:

“I’m delighted to continue being a part of the team in C4DM. Complementary to my work in industry, at QMUL I am excited to continue my work in applied AI for visual and audio domains. Most recently I have been working in environmental sound scene analysis for multiple tasks, such as audio geotagging. But additionally I have been creating partnerships across QM including clinicians at the St Barts NHS trust to use AI to support healthcare and patients. “

To learn more about Yogi and her work, you can read this recent interview in Wonk Magazine.

Welcoming new Lecturer: Huy Phan

We’re pleased to welcome new Lecturer Huy Phan to our group!

Huy is a Lecturer in AI, and joined the C4DM in April this year. His interests are a great match to the Machine Listening Lab, and we look forward to working together (remotely and in person!). Huy says:

“I am a Lecturer in AI at C4DM. Before joining QMUL, I was a postdoctoral research assistant at the University of Oxford and a lecturer at the University of Kent. I received PhD degree from the University of Lübeck, Germany. I am interested in applying machine learning to temporal signal analysis and processing (e.g. audio, EEG).

“At C4DM, I hope to join force with colleagues and students to make contribution to multi-view, multi-task, privacy-preserving, and non-iid generalisation perspectives of machine learning algorithms. I will focus on applications like audio event detection and localisation, audio scene classification, speech enhancement, and healthcare.”

New journal papers from the Machine Listening Lab

The Machine Listening Lab has recently had great success towards publishing journal papers related to the lab’s research priorities on developing new machine learning and signal processing methodologies for audio and timeseries analysis. Our new work ranges from new methods for speaker anti-spoofing, to visibility graphs for large-scale time series analysis, and on new evaluation methodologies for music prediction and transcription.

The list of our recently accepted and published journal papers can be found below; many of them are freely available or have links to preprints so you can read them already:

MLLab papers at ICASSP 2020

On 4-8 May 2020, several MLLab researchers will participate virtually at the IEEE International Conference on Acoustics, Speech, and Signal Processing (ICASSP 2020). ICASSP is the flagship conference of the IEEE’s Signal Processing Society and is the leading conference in the field of signal processing. For this year, ICASSP is organised as a virtual conference offering free registration to attendees.

As in previous years, the Machine Listening Lab will have a strong presence at the conference, both in terms of numbers and overall impact. The following papers authored/co-authored by MLLab members will be presented:

Research visit: Akash Jaiswal – Machine learning to analyse acoustic bird monitoring data

This week we are welcoming Akash Jaiswal, a PhD student from Jawaharlal Nehru University (Delhi, India). Akash has obtained a Newton-Bhabha Fund PhD placement to spend 3 months in the UK working with us on using machine learning to analyse acoustic bird monitoring data.

The placement description is as follows:

Worldwide increasing urbanization is directly associated with the rapid transformation of landscapes, impacting more and more natural habitats. Biodiversity assessment is essential to improve the management and quality of these habitats for greater biodiversity benefit and better provisioning of ecosystem services, and also to understand the ecological changes shaping urban animal communities. Birds are representative taxa for biodiversity monitoring in terrestrial habitats and have been studied frequently in this context. It has been observed that bird communities in habitats close to urban infrastructures exhibit reduced species richness with a few successful species more dominant as compared to adjacent natural habitats. But the mechanisms creating such community-level changes are poorly understood.

My PhD project is to understand such variations in bird communities across different habitats in a fast changing urban landscape like Delhi using birds’ singing activity as proxy for community composition. Acoustic monitoring of vocalizing animal communities proves to be less time-consuming and more resource-efficient as compared to field surveys of biodiversity. In this context, the aim of this research work is to assess the efficacy of using eco-acoustic indices to measure and characterize avian biodiversity, and its application to account for community-level variation in vocalizing birds (avian soundscape).

Although acoustic monitoring appears to be a promising solution for biodiversity assessment, the analysis of recorded acoustic samples remains challenging as the manual detection and identification of individual species vocalization from the large amount of field recordings is nearly impossible and also subject to observer bias/error. Automation of such analysis using machine learning techniques can facilitate identification of species and data analysis. Dr Dan Stowell at Queen Mary University of London has been working upon machine learning techniques to study sound signals including birdsongs, music and environmental sounds for years. He is also working on automated processes for analyzing large amounts of sound recordings – detecting the bird sounds and their relation to each other.

I am visiting Dr Stowell’s lab and working under his supervision to learn and use machine learning methods and automated processes to facilitate the analysis of the large amount of audio data I am collecting during my field sampling. Besides, I also believe that his supervision will certainly improve the quality and impact of my research work. This is certainly going to help in applicability of this modern technique to enhance my current and future projects.
