Researchers have introduced CrossBERT, a novel text encoder architecture designed to overcome the limitations of BERT-style models. Unlike BERT, which conflates representation learning with token reconstruction, CrossBERT separates these two objectives. This architectural change allows for higher masking ratios and improved gradient collection, leading to a 1.5x to 2x increase in throughput and a 2x improvement in sample efficiency. CrossBERT demonstrates consistent scaling and achieves superior performance on benchmarks like MTEB(eng, v2) and frozen GLUE. AI
