A.1 Deriving the Optimum of the KL-Constrained Reward Maximization Objective In this appendix, we will derive Eq. 4. Analogously to Eq. 3, we optimize the following objective: max

Open-World Object Detection (OWOD) is a challenging task that requires the detector to identify unlabeled objects and continuously demands the detector to learn new knowledge based on existing ones. Existing methods primarily focus on recalling unknown objects, neglecting to explore the reasons behind them. This paper aims to understand the model's behavior in predicting the unknown category.

Consequently, recent research efforts have focused on developing pre-trained TS forecasting models.

The warping estimation module W is based on an hourglass with five conv3 3 - bn - relu - pool2 2 in the encoders and five upsample2 2 - conv3 3 - bn - relu blocks in the decoders. In G, we use the Johnson architecture [ 3 ] with two down-sampling blocks, six residual-blocks and two up-sampling blocks. The design follows [ 7 ]. The inputs are the base image, displacement field, and inpainting map. It downsampled 4 and upsampled 4 to get the output, i.e. the reconstructed image.

Pose estimation is remarkably successful under supervised learning, but obtaining annotations, especially for new deployments, is costly and time-consuming. This work tackles adapting models trained on synthetic data to real-world target domains with only unlabelled data. A common approach is model fine-tuning with pseudo-labels from the target domain; yet many pseudo-labelling strategies cannot provide sufficient high-quality pose labels. This work proposes a reconstruction-based strategy as a complement to pseudo-labelling for synthetic-to-real domain adaptation. We generate the driving image by geometrically transforming a base image according to the predicted keypoints and enforce a reconstruction loss to refine the predictions. It provides a novel solution to effectively correct confident yet inaccurate keypoint locations through image reconstruction in domain adaptation. Our approach outperforms the previous state-of-the-arts by 8% for PCK on four large-scale hand and human real-world datasets. In particular, we excel on endpoints such as fingertips and head, with 7.2% and 29.9% improvements in PCK.

Membership inference arises in these contexts as a potential auditing method for detecting unauthorized data usage.
