Key Design Choices in Source-Free Unsupervised Domain Adaptation: An In-depth Empirical Analysis

no code implementations25 Feb 2024 Andrea Maracani, Raffaello Camoriano, Elisa Maiettini, Davide Talon, Lorenzo Rosasco, Lorenzo Natale

This study provides a comprehensive benchmark framework for Source-Free Unsupervised Domain Adaptation (SF-UDA) in image classification, aiming to achieve a rigorous empirical understanding of the complex relationships between multiple key design factors in SF-UDA methods.

Learn Fast, Segment Well: Fast Object Segmentation Learning on the iCub Robot

1 code implementation27 Jun 2022 Federico Ceola, Elisa Maiettini, Giulia Pasquale, Giacomo Meanti, Lorenzo Rosasco, Lorenzo Natale

In this work, we focus on the instance segmentation task and provide a comprehensive study of different techniques that allow adapting an object segmentation model in presence of novel objects or different domains.

Grasp Pre-shape Selection by Synthetic Training: Eye-in-hand Shared Control on the Hannes Prosthesis

1 code implementation18 Mar 2022 Federico Vasile, Elisa Maiettini, Giulia Pasquale, Astrid Florio, Nicolò Boccardo, Lorenzo Natale

In order to overcome the lack of data of this kind and reduce the need for tedious data collection sessions for training the system, we devise a pipeline for rendering synthetic visual sequences of hand trajectories.

From Handheld to Unconstrained Object Detection: a Weakly-supervised On-line Learning Approach

no code implementations28 Dec 2020 Elisa Maiettini, Andrea Maracani, Raffaello Camoriano, Giulia Pasquale, Vadim Tikhanoff, Lorenzo Rosasco, Lorenzo Natale

We show that the robot can improve adaptation to novel domains, either by interacting with a human teacher (Active Learning) or with an autonomous supervision (Semi-supervised Learning).

Fast Object Segmentation Learning with Kernel-based Methods for Robotics

1 code implementation25 Nov 2020 Federico Ceola, Elisa Maiettini, Giulia Pasquale, Lorenzo Rosasco, Lorenzo Natale

Our approach is validated on the YCB-Video dataset which is widely adopted in the computer vision and robotics community, demonstrating that we can achieve and even surpass performance of the state-of-the-art, with a significant reduction (${\sim}6\times$) of the training time.

Speeding-up Object Detection Training for Robotics with FALKON

no code implementations23 Mar 2018 Elisa Maiettini, Giulia Pasquale, Lorenzo Rosasco, Lorenzo Natale

We address the size and imbalance of training data by exploiting the stochastic subsampling intrinsic into the method and a novel, fast, bootstrapping approach.
