Fast SR-UNet
Architecture and GAN-based training procedure for obtaining a fast neural network which enable better bitrate performances respect to the H.265 codec for the same quality, or better quality at the same bitrate.
The Florence 4D Facial Expression Dataset
Dataset of 4D dynamic sequences of 3D faces with varying facial expressions
Stationary Representations: Optimally Approximating Compatibility and Implications for Improved Model Replacements
d-Simplex classifiers achieve stationary, compatible features, enabling seamless model updates in retrieval systems.
CL2R: Compatible Lifelong Learning Representations
A novel dataset of dynamic sequences of 3D face models, where a combination of synthetic and real identities exhibit an unprecedented variety of 4D facial expressions, with variations that include the classical neutral-apex transition, but generalize to e...
Regular Polytope Networks
Using fixed classifiers derived from regular polytopes to enhance neural network efficiency and accuracy by generating stationary, maximally-separated feature representations.
Elastic Feature Consolidation For Cold Start Exemplar-Free Incremental Learning
Elastic Feature Consolidation (EFC), exploits a tractable second-order approximation of feature drift based on an Empirical Feature Matrix (EFM).
Planckian jitter: enhancing the color quality of self-supervised visual representations
We propose a more realistic, physics-based color data augmentation - which we call Planckian Jitter.
Long-Tailed Class Incremental Learning
We propose a two-stage learning baseline with a learnable weight scaling layer for reducing the bias caused by long-tailed distribution in LT-CIL and which in turn also improves the performance of conventional CIL due to the limited exemplars.
Synthetic Social Agents (SSA) dataset
Synthetic Social Agents (SSA) is intended to be an oversimplification of real social behaviors, yet offers a challenging shift of attention from individual motion to social forces.
Smemo: Social memory for trajectory forecasting
Neural network based on an end-to-end trainable working memory, which acts as an external storage where information about each agent can be continuously written, updated and recalled
Auto Tagging
Image Auto Tagging technology enables automatic assignment of relevant tags or keywords to vast collections of images and videos.
