Sentiment Analysis on Encrypted Data with Homomorphic Encryption
This Hugging Face blog post demonstrates running sentiment analysis on fully homomorphic encrypted (FHE) data, enabling inference without the server ever seeing plaintext inputs. The approach combines a fine-tuned NLP model with Concrete-ML, a library that compiles ML models to FHE circuits. This represents a practical demonstration of privacy-preserving ML inference at the application layer.
Text Analytics Evaluation Framework: Benchmarking LLMs on Social Media NLP Tasks
Researchers introduce a 470-question evaluation framework to assess LLM performance on aggregated social media text, applied to Twitter datasets across sentiment analysis, hate speech detection, and emotion recognition. Results show performance degrades substantially as input scale exceeds 500 instances, particularly for open-weights models on numerical tasks. Multi-label and target-dependent scenarios also show notable performance drops, and task complexity progressively erodes accuracy from basic semantic identification to comparison and counting operations. The findings point to architectural bottlenecks in current LLMs for rigorous quantitative analysis over large text collections.
