Selected Research
My main research interest is currently around generative models for image and video synthesis or editing. I remain curious about developments on open problems I have worked with in the past, such as efficient video processing, out-of-distribution detection and continual learning.
A full publication list can be found on my scholar page.

Delta Distillation for Efficient Video Processing
Amirhossein Habibian,
Haitam Ben Yahia,
Davide Abati,
Efstratios Gavves,

Instead of distilling neural networks activations, we teach a student network to regress their temporal differences, allowing an improved cost-performance tradeoff.

Skip-Convolutions for Efficient Video Processing
Amirhossein Habibian,
Davide Abati,
Taco Cohen,
Babak Ehteshami Bejnordi
CVPR, 2021
arXiv  /

By selectively applying convolutions only on locations that carry meaningful information, the computational cost of neural networks on video can be reduced by 4~5 times.

Dark Experience for General Continual Learning: a Strong, Simple Baseline
Pietro Buzzega,
Matteo Boschini,
Angelo Porrello,
Davide Abati,
Simone Calderara
NeurIPS, 2020
arXiv  / 
bibtex  / 
code
We tackle general continual learning, where an agent is required to learn multiple tasks in a sequence under minimal assumptions about their nature.
We run an extensive comparison of many existing methods and introduce a simple model based on knowledge distillation outperforming all of them.
