Searching to Exploit Memorization Effect in Learning with Noisy Labels
Sample selection approaches are popular in robust learning from noisy labels.
Positive-Unlabeled Node Classification with Structure-aware Graph Learning
We also propose a regularizer to align the model with graph structure.
Implicit Concept Removal of Diffusion Models
To address this, we utilize the intrinsic geometric characteristics of implicit concepts and present the Geom-Erasing, a novel concept removal method based on geometric-driven control.
PixArt-$α$: Fast Training of Diffusion Transformer for Photorealistic Text-to-Image Synthesis
We hope PIXART-$\alpha$ will provide new insights to the AIGC community and startups to accelerate building their own high-quality yet low-cost generative models from scratch.
GrowCLIP: Data-aware Automatic Model Growing for Large-scale Contrastive Language-Image Pre-training
Compared with the existing methods, GrowCLIP improves 2. 3% average top-1 accuracy on zero-shot image classification of 9 downstream tasks.
Non-autoregressive Conditional Diffusion Models for Time Series Prediction
In this paper, we propose TimeDiff, a non-autoregressive diffusion model that achieves high-quality time series prediction with the introduction of two novel conditioning mechanisms: future mixup and autoregressive initialization.
Nonparametric Iterative Machine Teaching
In this paper, we consider the problem of Iterative Machine Teaching (IMT), where the teacher provides examples to the learner iteratively such that the learner can achieve fast convergence to a target model.
An Adaptive Policy to Employ Sharpness-Aware Minimization
Sharpness-aware minimization (SAM), which searches for flat minima by min-max optimization, has been shown to be useful in improving model generalization.
Leveraging per Image-Token Consistency for Vision-Language Pre-training
(2) Under-utilization of the unmasked tokens: CMLM primarily focuses on the masked token but it cannot simultaneously leverage other tokens to learn vision-language associations.
Low-rank Tensor Learning with Nonconvex Overlapped Nuclear Norm Regularization
While the optimization problem is nonconvex and nonsmooth, we show that its critical points still have good statistical performance on the tensor completion problem.
Effective Meta-Regularization by Kernelized Proximal Regularization
We study the problem of meta-learning, which has proved to be advantageous to accelerate learning new tasks with a few samples.

We propose a MUlti-Subspace structured Meta-Learning (MUSML) algorithm to learn the subspace bases.
Fast Deterministic Stackelberg Actor-Critic
Most advanced Actor-Critic (AC) approaches update the actor and critic concurrently through (stochastic) Gradient Descents (GD), which may be trapped into bad local optimality due to the instability of these simultaneous updating schemes.
Improving Meta-Continual Learning Representations with Representation Replay
In this paper, we remove this inconsistency in the use of ER and improve continual learning representations by integrating ER also into meta-training.
Timeseries Anomaly Detection using Temporal Hierarchical One-Class Network
This allows the temporal dynamics to be well captured by a set of multi-resolution temporal clusters.
Normalization Helps Training of Quantized LSTM
The long-short-term memory (LSTM), though powerful, is memory and computa\x02tion expensive.

Machine learning has been highly successful in data-intensive applications but is often hampered when the data set is small.

Collaborative filtering (CF) has been one of the most important and popular recommendation methods, which aims at predicting users' preferences (ratings) based on their past behaviors.
Fast Second Order Stochastic Backpropagation for Variational Inference
We propose a second-order (Hessian or Hessian-free) based optimization method for variational inference inspired by Gaussian backpropagation, and argue that quasi-Newton optimization can be developed as well.
