Multi-View Unsupervised Image Generation with Cross Attention Guidance

no code implementations7 Dec 2023 Llukman Cerkezi, Aram Davtyan, Sepehr Sameni, Paolo Favaro

The growing interest in novel view synthesis, driven by Neural Radiance Field (NeRF) models, is hindered by scalability issues due to their reliance on precisely annotated multi-view images.

Spatio-Temporal Crop Aggregation for Video Representation Learning

no code implementations ICCV 2023 Sepehr Sameni, Simon Jenni, Paolo Favaro

We propose Spatio-temporal Crop Aggregation for video representation LEarning (SCALE), a novel method that enjoys high scalability at both training and inference time.

Representation Learning by Detecting Incorrect Location Embeddings

1 code implementation10 Apr 2022 Sepehr Sameni, Simon Jenni, Paolo Favaro

We represent object parts with image tokens and train a ViT to detect which token has been combined with an incorrect positional embedding.

KOALA: A Kalman Optimization Algorithm with Loss Adaptivity

no code implementations7 Jul 2021 Aram Davtyan, Sepehr Sameni, Llukman Cerkezi, Givi Meishvilli, Adam Bielski, Paolo Favaro

Moreover, we show that the Kalman Filter dynamical model for the evolution of the unknown parameters can be used to capture the gradient dynamics of advanced methods such as Momentum and Adam.
