Machine learning algorithms have become a very essential tool in the fields of math and engineering, as well as for industrial purposes (fabric, medicine, sport, etc.). This research leverages classical machine learning algorithms for innovative accurate and efficient fabric protrusion detection. We present an approach for improving model training with a small dataset. We use a few classic statistics machine learning algorithms (decision trees, logistic regression, etc.) and a fully connected neural network (NN) model. We also present an approach to optimize a model accuracy rate and execution time for finding the best accuracy using parallel processing with Dask (Python).

We introduce VAULT, a fully automated adversarial RAG pipeline that systematically uncovers and remedies weaknesses in NLI models through three stages: retrieval, adversarial generation, and iterative retraining. First, we perform balanced few-shot retrieval by embedding premises with both semantic (BGE) and lexical (BM25) similarity. Next, we assemble these contexts into LLM prompts to generate adversarial hypotheses, which are then validated by an LLM ensemble for label fidelity. Finally, the validated adversarial examples are injected back into the training set at increasing mixing ratios, progressively fortifying a zero-shot RoBERTa-base model.On standard benchmarks, VAULT elevates RoBERTa-base accuracy from 88.48% to 92.60% on SNLI +4.12%, from 75.04% to 80.95% on ANLI +5.91%, and from 54.67% to 71.99% on MultiNLI +17.32%. It also consistently outperforms prior in-context adversarial methods by up to 2.0% across datasets. By automating high-quality adversarial data curation at scale, VAULT enables rapid, human-independent robustness improvements in NLI inference tasks.
