Test time adaptation is the process of adapting, in an unsupervised manner, a pre-trained source model to each incoming batch of the test data (i. e., without requiring a substantial portion of the test data to be available, as in traditional domain adaptation) and without access to the source data.

This challenge arises because these models struggle to generalize beyond their training datasets, and the variety of occlusions is hard to capture in the training data.

By restoring the knowledge from the source, it effectively corrects the negative consequences arising from the gradual deterioration of model parameters caused by ongoing shifts in the domain.

To address this limitation, we focus on the task of source-free domain adaptation for pose estimation, where a source model must adapt to a new target domain using only unlabeled target data.

In this work, we relax both of these assumptions by addressing the problem of adapting a set of models trained independently on uni-modal data to a target domain consisting of unlabeled multi-modal data, without having access to the original source dataset.

In contrast to the existing dynamic multi-task approaches that adjust only the weights within a fixed architecture, our approach affords the flexibility to dynamically control the total computational cost and match the user-preferred task importance better.

However, it is a critical task in many applications like environmental monitoring, where the number of labeled examples for each class is limited.

Once this correspondence is found, we can directly transfer the demonstrations on one domain to the other and use it for imitation.

A recent line of work addressed this problem and proposed an algorithm that transfers knowledge to the unlabeled target domain from a single source model without requiring access to the source data.

While supervised techniques in re-identification are extremely effective, the need for large amounts of annotations makes them impractical for large camera networks.

In order to cope with this issue, we introduce the problem of learning person re-identification models from videos with weak supervision.

Time series shapelets are discriminative sub-sequences and their similarity to time series can be used for time series classification.
