Evaluating & enhancing deep learning systems via out-of-distribution detection
Published 2022“…Then, we propose an OOD testing criteria to enhance error discovery and propose distribution aware robustness enhancement by showing that filtering errors far from the trained distribution increases robustness by 21.5\%. We then enhance the field of OOD by introducing a fine-grained OOD technique assessing the ground truth of data augmentation and increasing accuracy by 31.9\% by guiding data augmentation selection with distribution awareness. …”

Evaporation and crystallisation of saline droplet with surfactant on smooth surfaces
Published 2023“…Recommended future work could include exploring the effects of varying different concentrations of NaCl below the supersaturation concentration range (1-15% of NaCl) and varying different concentrations of surfactants at the critical micelle concentration (CMC) levels (1-1.5 CMC). This could potentially offer new insights into the evaporative and crystallisation behaviour of the droplets, as well as new deposition patterns.…”
