A Qwen3-4B-based general text embedding model from the TIME group at ICT-CAS in collaboration with Querit. Applies BOOM (Bagging-based rObust mOdel Merging), training multiple embedding models on bootstrap-sampled subsets of the multi-task corpus and linearly merging them, to deliver ensemble-like robustness and OOD generalization at single-model inference cost; supports lightweight incremental updates via merge-in.
