DSP: Dynamic Sequence Parallelism for Multi-Dimensional Transformers

ICML 2025poster

Scaling multi-dimensional transformers to long sequences is indispensable across various domains. However, the challenges of large memory requirements and slow speeds of such sequences necessitate sequence parallelism. All existing approaches fall under the category of embedded sequence parallelism,…

MERIT: Maximum-normalized Element-wise Ratio for Language Model Large-batch Training

ICML 2025poster

Large-batch training has become a cornerstone in accelerating the training of deep neural networks, yet it poses challenges in optimization and generalization. Existing optimizers like AdamW present performance degradation during language models' large-batch training, due to the information bottlen…

How Does the Textual Information Affect the Retrieval of Multimodal In-Context Learning?

EMNLP 2024main

The increase in parameter size of multimodal large language models (MLLMs) introduces significant capabilities, particularly multimodal in-context learning, where MLLMs enhance task performance without updating pre-trained parameters. However, this effectiveness hinges on the appropriate selection o…

InfoBatch: Lossless Training Speed Up by Unbiased Dynamic Data Pruning

ICLR 2024oral

Data pruning aims to obtain lossless performances with less overall cost. A common approach is to filter out samples that make less contribution to the training. This could lead to gradient expectation bias compared to the original data. To solve this problem, we propose InfoBatch, a novel framework…

OpenMoE: An Early Effort on Open Mixture-of-Experts Language Models

ICML 2024poster

To help the open-source community have a better understanding of Mixture-of-Experts (MoE) based large language models (LLMs), we train and release OpenMoE, a series of fully open-sourced and reproducible decoder-only MoE LLMs, ranging from 650M to 34B parameters and trained on up to over 1T tokens.…

A Study on Transformer Configuration and Training Objective

ICML 2023poster

Transformer-based models have delivered impressive results on many tasks, particularly vision and language tasks. In many model training situations, conventional configurations are often adopted. For example, we usually set the base model with hidden size (i.e. model width) to be 768 and the number…

CAME: Confidence-guided Adaptive Memory Efficient Optimization

ACL 2023long

Adaptive gradient methods, such as Adam and LAMB, have demonstrated excellent performance in the training of large language models. Nevertheless, the need for adaptivity requires maintaining second-moment estimates of the per-parameter gradients, which entails a high cost of extra memory overheads.…

CowClip: Reducing CTR Prediction Model Training Time from 12 Hours to 10 Minutes on 1 GPU

AAAI 2023technical

The click-through rate (CTR) prediction task is to predict whether a user will click on the recommended item. As mind-boggling amounts of data are produced online daily, accelerating CTR prediction model training is critical to ensuring an up-to-date model and reducing the training cost. One approac…

Preventing Zero-Shot Transfer Degradation in Continual Learning of Vision-Language Models

ICCV 2023poster

Continual learning (CL) can help pre-trained vision-language models efficiently adapt to new or under-trained data distributions without re-training. Nevertheless, during the continual training of the Contrastive Language-Image Pre-training (CLIP) model, we observe that the model's zero-shot transfe…

To Repeat or Not To Repeat: Insights from Scaling LLM under Token-Crisis

NeurIPS 2023poster

Recent research has highlighted the importance of dataset size in scaling language models. However, large language models (LLMs) are notoriously token-hungry during pre-training, and high-quality text data on the web is likely to be approaching its scaling limit for LLMs. To further enhance LLMs, a…

Prototypical Cross-Domain Self-Supervised Learning for Few-Shot Unsupervised Domain Adaptation

CVPR 2021poster

Unsupervised Domain Adaptation (UDA) transfers predictive models from a fully-labeled source domain to an unlabeled target domain. In some applications, however, it is expensive even to collect labels in the source domain, making most previous works impractical. To cope with this problem, recent wor…
