Sim2Real in Reconstructive Spectroscopy: Deep Learning with Augmented Device-Informed Data Simulation
This work proposes a deep learning (DL)-based framework, namely Sim2Real, for spectral signal reconstruction in reconstructive spectroscopy, focusing on efficient data sampling and fast inference time.
Near-Interpolators: Rapid Norm Growth and the Trade-Off between Interpolation and Generalization
Under a random matrix theoretic assumption on the data distribution and an eigendecay assumption on the data covariance matrix $\boldsymbol{\Sigma}$, we demonstrate that any near-interpolator exhibits rapid norm growth: for $\tau$ fixed, $\boldsymbol{\beta}$ has squared $\ell_2$-norm $\mathbb{E}[\|{\boldsymbol{\beta}}\|_{2}^{2}] = \Omega(n^{\alpha})$ where $n$ is the number of samples and $\alpha >1$ is the exponent of the eigendecay, i. e., $\lambda_i(\boldsymbol{\Sigma}) \sim i^{-\alpha}$.
VOOM: Robust Visual Object Odometry and Mapping using Hierarchical Landmarks
Meanwhile, local bundle adjustment is performed utilizing the objects and points-based covisibility graphs in our visual object mapping process.
Make-A-Character: High Quality Text-to-3D Character Generation within Minutes
There is a growing demand for customized and expressive 3D characters with the emergence of AI agents and Metaverse, but creating 3D characters using traditional computer graphics tools is a complex and time-consuming task.
Unified Binary and Multiclass Margin-Based Classification
The notion of margin loss has been central to the development and analysis of algorithms for binary classification.
Neural Collapse in Multi-label Learning with Pick-all-label Loss
We study deep neural networks for the multi-label classification (MLab) task through the lens of neural collapse (NC).
Diversity from Human Feedback
DivHF learns a behavior descriptor consistent with human preference by querying human feedback.
Benign Overfitting and Grokking in ReLU Networks for XOR Cluster Data
Second, they can undergo a period of classical, harmful overfitting -- achieving a perfect fit to training data with near-random performance on test data -- before transitioning ("grokking") to near-optimal generalization later in training.
UniG-Encoder: A Universal Feature Encoder for Graph and Hypergraph Node Classification
In this work, a universal feature encoder for both graph and hypergraph representation learning is designed, called UniG-Encoder.

On Classification-Calibration of Gamma-Phi Losses
Gamma-Phi losses constitute a family of multiclass classification loss functions that generalize the logistic and other common losses, and have found application in the boosting literature.
Heterogeneous Multi-agent Zero-Shot Coordination by Coevolution
Generating agents that can achieve zero-shot coordination (ZSC) with unseen partners is a new challenge in cooperative multi-agent reinforcement learning (MARL).
MORE: A Metric Learning Based Framework for Open-domain Relation Extraction
To address these problems, in this work, we propose a novel learning framework named MORE (Metric learning-based Open Relation Extraction).
Consistent Interpolating Ensembles via the Manifold-Hilbert Kernel
Recent research in the theory of overparametrized learning has sought to establish generalization guarantees in the interpolating regime.

Learning from Label Proportions by Learning with Label Noise
Learning from label proportions (LLP) is a weakly supervised classification problem where data points are grouped into bags, and the label proportions within each bag are observed instead of the instance-level labels.
FCMNet: Full Communication Memory Net for Team-Level Cooperation in Multi-Agent Systems
There, our comparison results show that FCMNet outperforms state-of-the-art communication-based reinforcement learning methods in all StarCraft II micromanagement tasks, and value decomposition methods in certain tasks.
VC dimension of partially quantized neural networks in the overparametrized regime
Indeed, existing applications of VC theory to large networks obtain upper bounds on VC dimension that are proportional to the number of weights, and for a large class of networks, these upper bound are known to be tight.
Evolutionary Diversity Optimization with Clustering-based Selection for Reinforcement Learning
However, due to the inefficient selection mechanisms, these methods cannot fully guarantee both high quality and diversity.
Real-Time Video Super-Resolution on Smartphones with Deep Learning, Mobile AI 2021 Challenge: Report

Next, we perform exploratory data analysis to delve into the data.
Weston-Watkins Hinge Loss and Ordered Partitions
A recent empirical comparison of nine such formulations [Do\v{g}an et al. 2016] recommends the variant proposed by Weston and Watkins (WW), despite the fact that the WW-hinge loss is not calibrated with respect to the 0-1 loss.
Weak Supervision Enhanced Generative Network for Question Generation
More specifically, we devise a discriminator, Relation Guider, to capture the relations between the whole passage and the associated answer and then the Multi-Interaction mechanism is deployed to transfer the knowledge dynamically for our question generation system.
