Exploring Deep Neural Networks on Edge TPU

no code implementations17 Oct 2021 Seyedehfaezeh Hosseininoorbin, Siamak Layeghy, Brano Kusy, Raja Jurdak, Marius Portmann

Based on the use of a joint-time-frequency data representation, also known as spectrogram, we explore the trade-off between classification performance and the energy consumed for inference.

Exploring Edge TPU for Network Intrusion Detection in IoT

no code implementations30 Mar 2021 Seyedehfaezeh Hosseininoorbin, Siamak Layeghy, Mohanad Sarhan, Raja Jurdak, Marius Portmann

The focus of this paper is the exploration of deep learning-based NIDS at the edge of IoT, and in particular the computational and energy efficiency.

Deep Learning-based Cattle Activity Classification Using Joint Time-frequency Data Representation

no code implementations6 Nov 2020 Seyedeh Faezeh Hosseini Noorbin, Siamak Layeghy, Brano Kusy, Raja Jurdak, Greg Bishop-hurley, Marius Portmann

The key results of this paper is that the joint time-frequency data representation, even when used in conjunction with a relatively basic neural network classifier, can outperform the best cattle activity classifiers reported in the literature.

Deep Representation Learning in Speech Processing: Challenges, Recent Advances, and Future Trends

no code implementations2 Jan 2020 Siddique Latif, Rajib Rana, Sara Khalifa, Raja Jurdak, Junaid Qadir, Björn W. Schuller

Research on speech processing has traditionally considered the task of designing hand-engineered acoustic features (feature engineering) as a separate distinct problem from the task of designing efficient machine learning (ML) models to make prediction and classification decisions.

Genetic Programming for Smart Phone Personalisation

no code implementations11 Aug 2014 Philip Valencia, Aiden Haak, Alban Cotillon, Raja Jurdak

We introduce the concept of collaborative smart phone personalisation through the GP Island Model, in order to exploit shared context among co-located phone users and reduce convergence time.
