Improving Generalizability of Graph Anomaly Detection Models via Data Augmentation
In this paper, we base on the phenomenon and propose a general and novel research problem of generalized graph anomaly detection that aims to effectively identify anomalies on both the training-domain graph and unseen testing graph to eliminate potential dangers.
SC-VAE: Sparse Coding-based Variational Autoencoder with Learned ISTA
Several variants of variational autoencoders (VAEs) have been proposed to learn compact data representations by encoding high-dimensional data in a lower dimensional space.
Biofilms as self-shaping growing nematics
Active nematics are the nonequilibrium analog of passive liquid crystals in which anisotropic units consume free energy to drive emergent behavior.
Improving Generalizability of Graph Anomaly Detection Models via Data Augmentation
In this paper, we base on the phenomenon and propose a general and novel research problem of generalized graph anomaly detection that aims to effectively identify anomalies on both the training-domain graph and unseen testing graph to eliminate potential dangers.
Unseen Anomaly Detection on Networks via Multi-Hypersphere Learning
Network anomaly detection is a crucial task since a few anomalies can cause huge losses.
Subtractive Aggregation for Attributed Network Anomaly Detection
It aims to detect nodes that significantly deviate from their corresponding background.
From Point to Space: 3D Moving Human Pose Estimation Using Commodity WiFi
To reconstruct 3D poses of people who move throughout the space rather than a fixed point, we fuse the amplitude and phase into Channel State Information (CSI) images which can provide both pose and position information.
Subject-independent Human Pose Image Construction with Commodity Wi-Fi
Existing papers achieve good results when constructing the images of subjects who are in the prior training samples.
Statistical Guarantees for Transformation Based Models with Applications to Implicit Variational Inference
More recently, transformation-based models have been used in variational inference (VI) to construct flexible implicit families of variational distributions.
PHICON: Improving Generalization of Clinical Text De-identification Models via Data Augmentation
De-identification is the task of identifying protected health information (PHI) in the clinical text.
When Healthcare Meets Off-the-Shelf WiFi: A Non-Wearable and Low-Costs Approach for In-Home Monitoring
The proposed approach can capture fine-grained human pose figures even through a wall and track detailed respiration status simultaneously by off-the-shelf WiFi devices.
The Data Analysis Pipeline for the SDSS-IV MaNGA IFU Galaxy Survey: Overview
We summarize assessments of the precision and accuracy of our measurements as a function of signal-to-noise and other salient metrics, noting that additional analysis and discussion of emission-line diagnostics are provided in our companion paper, Belfiore et al.

Revisiting the proton-radius problem using constrained Gaussian processes
We have shown the impact of the physical constraints imposed on the form factor and of the range of experimental data used.

A New Nonparametric Estimate of the Risk-Neutral Density with Applications to Variance Swaps
We develop a new nonparametric approach for estimating the risk-neutral density of asset prices and reformulate its estimation into a double-constrained optimization problem.
Adaptive posterior convergence rates in non-linear latent variable models
In this article, we study rates of posterior contraction in univariate density estimation for a class of non-linear latent variable models where unobserved U(0, 1) latent variables are related to the response variables via a random non-linear regression with an additive error.
