- Abstract: Universal domain adaptation (UniDA) is a practical but challenging problem,
in which information about the relation between the source and the target
domains is not given for knowledge transfer. Existing UniDA methods may suffer
from the problems of overlooking intra-domain variations in the target domain
and difficulty in separating between the similar known and unknown class. To
address these issues, we propose a novel Mutual Learning Network (MLNet) with
neighborhood invariance for UniDA. In our method, confidence-guided invariant
feature learning with self-adaptive neighbor selection is designed to reduce
the intra-domain variations for more generalizable feature representation. By
using the cross-domain mixup scheme for better unknown-class identification,
the proposed method compensates for the misidentified known-class errors by
mutual learning between the closed-set and open-set classifiers. Extensive
experiments on three publicly available benchmarks demonstrate that our method
achieves the best results compared to the state-of-the-arts in most cases and
significantly outperforms the baseline across all the four settings in UniDA.

Universal Domain Adaptation (UniDA) aims to transfer knowledge from a labeled source domain to an unlabeled target domain.
We show that state-of-the-art methods struggle when the source domain has significantly more non-overlapping classes than overlapping ones.
We propose using self-supervised learning to preserve the structure of the target data.

Federated learning is a distributed machine learning approach which enables a shared server model to learn by aggregating the locally-computed parameter updates with the training data from spatially-distributed client silos.
We propose the Federated Invariant Learning Consistency (FedILC) approach, which leverages the gradient covariance and the geometric mean of Hessians to capture both inter-silo and intra-silo consistencies.
This is relevant to various fields such as medical healthcare, computer vision, and the Internet of Things (IoT)
