Before revision:  Motivated by applications in the integration of multiple (point-wise mutual information) PMI matrices , we propose the model {\bf B} lockwise missing {\bf E}mbedding {\bf L}earning {\bf T}ransformer (BELT) to treat row-wise/column-wise missingness.
After revision:  Motivated by applications in the integration of multiple Electronic Health Record (EHR) datasets , we propose the model {\bf B} lockwise missing {\bf E}mbedding {\bf L}earning {\bf T}ransformer (BELT) to treat row-wise/column-wise missingness.
