Research Paper Overview
Conan-Embedding-v2: Training an LLM from Scratch for Text Embeddings
Summary
Conan-embedding-v2 is a 1.4B-parameter large language model trained from scratch and fine-tuned for text embedding tasks. It incorporates news data and multilingual pairs to bridge data gaps and uses a novel soft-masking mechanism to transition between causal and bidirectional masks for better representation learning. The model also employs dynamic hard negative mining to improve training with difficult examples, achieving state-of-the-art performance on the Massive Text Embedding Benchmark and Chinese MTEB.
