Hacker News Show HN: Autofit2 – End-to-end pipeline for multilingual text classification

An 'integrated pipeline' for 'multilingual text classification' that works well for 'low-data regimes' (few-shot learning with SetFit), offers 'high throughput on CPUs,' and includes features like model cards, CO2 emissions estimation, and 'entropy-based bias analysis.'

An 'integrated pipeline' for 'multilingual text classification' that works well for 'low-data regimes' (few-shot learning with SetFit), offers 'high throughput on CPUs,' and includes features like model cards, CO2 emissions estimation, and 'entropy-based bias analysis.'
Autofit2 addresses critical enterprise needs in AI/ML operations, particularly for text-heavy applications requiring multilingual support and responsible AI practices. Its 'end-to-end pipeline' simplifies the deployment of text classification models, a common pain point for MLOps teams. The 'few-shot learning' capability with SetFit is a significant advantage for businesses with limited labeled data, accelerating model development. High throughput on CPUs makes it cost-effective and accessible for diverse deployment environments. Crucially, the inclusion of 'model cards,' 'CO2 emissions estimation,' and 'entropy-based bias analysis' aligns with growing regulatory and ethical demands for transparent and fair AI systems. This positions Autofit2 as a valuable tool for automated text moderation, customer support, and content analysis, enabling enterprises to build and deploy robust, accountable multilingual AI solutions efficiently.
Hi HN, Stefan here. autofit2 is a project I have been using at my previous company and is now opensourced. It has been used extensively in automated text moderation, but can be applied to any text/document classification task. We had success modeling offensive texts in 20+ languages (cf. github.com/neospe/dataload for all the datasets).It's an integrated pipeline for lightweight multilingual text classification, covering preprocessing, training, and evaluation. It implements SetFit, a few-shot learning technique that works well for low-data regimes (down to a few dozen examples), and offers high throughput on CPUs, since it's based on Sentence Transformers. Dependencies are kept lean, but of course PyTorch itself isn't exactly small.autofit2 takes a base model and a JSON config as input, and outputs a TorchServe model archive as well as a model card. The model card includes any benchmarks you have for your task, self-consistency tests, estimated CO2 emissions of the finetune, as well as an entropy-based bias analysis. For the bias eval, small test corpora for 50 languages are included. It works best with my EAR (Entropy-based Attention Regularization) fork of Sentence Transformers.Feedback is welcome.

How does this differ from SetFit? Is it just an alternative implementation?I found the HF version pretty effective and it often works well for multilingual classification. I've used it for intent matching and was pleasantly surprised that Polish, German and other translations of our intents tended to work "for free" when training with just English training data!https://github.com/huggingface/setfit
