Pixel-BERT replaces detector-region inputs with spatial feature cells from a CNN, which are combined with text tokens in a shared Transformer for image–language learning. The cells are pooled CNN features, not raw pixels. On VQA 2.0 test-dev, its ResNeXt-152 model reports 74.45 VQA-score, versus UNITER’s 72.27; this system comparison does not isolate the representation’s effect.
