Representation with Local Geometry Regularization Supplemental Material

Neural Information Processing Systems

We compare our method with four competing methods in Table 1 of the main paper. We also use the score reported by [5]. We found that the corner-based methods, e.g., HEA T and RoomFormer, fail to reconstruct the correct floorplans and are easily affected by the irregular Heat: Holistic edge attention transformer for structured reconstruction. Real-world perception for embodied agents.




MCL-GAN: GenerativeAdversarialNetworks withMultipleSpecializedDiscriminators

Neural Information Processing Systems

There are several GAN literature that adopts multiple discriminators [9-14]. Among them, GMAN [10] is closely related to our approach in the sense that it utilizes an ensemble predictionofdiscriminators.

We summarize the results in Table 1. In ranking literature, many evaluation metrics are often stated in terms of gain functions. When relevance scores are restricted to be binary (i.e. Before we do so, we need some more notation regarding F . By Proposition C.1, this implies that In this section, we prove Theorem 4.2 which characterizes the agnostic P AC learnability of an arbitrary hypothesis class We begin with Lemma C.2 which asserts that if for all ERM is an agnostic P AC learner for H w.r.t ` The proof of Lemma C.2 is similar to the proof of Lemma 4.3 and involves bounding the empirical Proposition C.1, this will imply that By Proposition C.1, this implies that Next, Lemma C.3 extends the learnability of The proof of Lemma C.3 follows the same the exact same strategy used in proving Lemma 4.4.




A Network Science Approach to Granular Time Series Segmentation

Time series segmentation (TSS) is one of the time series (TS) analysis techniques, that has received considerably less attention compared to other TS related tasks. In recent years, deep learning architectures have been introduced for TSS, however their reliance on sliding windows limits segmentation granularity due to fixed window sizes and strides. To overcome these challenges, we propose a new more granular TSS approach that utilizes the Weighted Dual Perspective Visbility Graph (WDPVG) TS into a graph and combines it with a Graph Attention Network (GAT). By transforming TS into graphs, we are able to capture different structural aspects of the data that would otherwise remain hidden. By utilizing the representation learning capabilities of Graph Neural Networks, our method is able to effectively identify meaningful segments within the TS. To better understand the potential of our approach, we also experimented with different TS-to-graph transformations and compared their performance. Our contributions include: a) formulating the TSS as a node classification problem on graphs; b) conducting an extensive analysis of various TS-to-graph transformations applied to TSS using benchmark datasets from the TSSB repository; c) providing the first detailed study on utilizing GNNs for analyzing graph representations of TS in the context of TSS; d) demonstrating the effectiveness of our method, which achieves an average F1 score of 0.97 across 59 diverse TSS benchmark datasets; e) outperforming the seq2point baseline method by 0.05 in terms of F1 score; and f) reducing the required training data compared to the baseline methods.
