I ran 580 experiments (yes, 580 π€―) to check if we can quantify data drift's impact on model performance using only drift metrics.
For these experiments, I built a technique that relies on drift signals to estimate model performance. I compared its results against the current SoTA performance estimation methods and checked which technique performs best.
The plot below summarizes the general results. It measures the quality of performance estimation versus the absolute performance change. (The lower, the better).
Inspired by the awesome work from @mlabonne, I created a Space to monitor the narrowing gap between open and proprietary LLMs as scored by the LMSYS Chatbot Arena ELO ratings π€
The goal is to have a continuously updated place to easily visualize these rapidly evolving industry trends π
As part of the Data is Better Together MPEP project, we are now at the point where some translation efforts have successfully translated 500 highly ranked prompts into a new target language (amazing work from @Rijgersberg et al!)
Our next step is to use these translated prompts to evaluate the performance of LLMs for non English languages.
Does LLM, as a judge, work outside of English?
Ideally, it would be compelling to leverage LLMs to judge models for non-English since this significantly lowers the barrier to evaluating models (although it doesn't remove this barrier altogether).
What we want to know is: - does auto/LLM eval work in general for a particular language - which model(s) works best as a judge - do LLMs' judgments of non-English models match human preferences?
We release Idefics2-8B, a foundation vision language model with SOTA results for its size on many benchmarks.
For Idefics2, we adopted a simple architecture: -Images are fed to a vision encoder, then to a modality projection to match the input dimension of the LLM, and finally to a perceiver resampler for efficient pooling. -Interleaved image-text data are then passed to the LLM.
During the pre-training: -The modality projection and perceiver resampler weights are newly initialized. -We start with pre-trained models for the vision encoder and the LLM, and continue the training with LoRA. -In total, we see 1.5T images!
We pre-train on 3 types of data, all publicly available: -Interleaved image-text documents: our dataset OBELICS HuggingFaceM4/OBELICS -Image caption pairs: only synthetic captions! -PDF documents: IDL and PDFA
We kept the aspect ratio of the images with the Patch n' Pack strategy, with a resolution of up to 980x980. At inference, it's also more efficient for lower-resolution images.
For the SFT, we build The Cauldron, a collection of 50 high-quality datasets in the user/assistant format. It is a ready-to-use dataset for the fine-tuning of any VLM. HuggingFaceM4/the_cauldron
Most current models, like LLaVA-NeXT, encode images with an excessive number of tokens, like 2880. Instead, we put a focus on being efficient at inference by training on a mix of images encoded with 64 tokens, and 320 tokens. The result is that we perform favorably compared to the best models in our size class, while being efficient at inference.
We present details and tips for training 1-bit LLMs. We also provide additional experiments and results that were not reported and responses to questions regarding the "The-Era-of-1-bit-LLM" paper. Finally, we include the official PyTorch implementation of BitNet (b1.58 and b1) for future research and development of 1-bit LLMs.
I'd like to share our project on open-type Named Entity Recognition (NER). Our model uses a transformer encoder (BERT-like), making the computation overhead very minimal compared to use of LLMs. I've developed a demo that runs on CPU on Google Colab.
