Improving Vision-and-Language Reasoning via Spatial Relations Modeling

no code implementations9 Nov 2023 Cheng Yang, Rui Xu, Ye Guo, Peixiang Huang, Yiru Chen, Wenkui Ding, Zhongyuan Wang, Hong Zhou

Further, we design two pre-training tasks named object position regression (OPR) and spatial relation classification (SRC) to learn to reconstruct the spatial relation graph respectively.

3 code implementations31 May 2016 Yin Zheng, Bangsheng Tang, Wenkui Ding, Hanning Zhou

This paper proposes CF-NADE, a neural autoregressive architecture for collaborative filtering (CF) tasks, which is inspired by the Restricted Boltzmann Machine (RBM) based CF model and the Neural Autoregressive Distribution Estimator (NADE).
