A systematic imputation framework for sparse, multimodal space biology datasets: application to retinal imaging and omics from the RR9 mission

Vaishnavi Nagesh, Lauren Sanders, Sylvain V. Costes…·Jian Gong

The paper presents a framework for imputing sparse, multimodal space biology datasets and shows that MICE-Elastic and a hybrid strategy preserve biological signal better than other methods.

Cross-Species Adaptation of RETFound for Rodent OCT Age Estimation Reveals Strong CNN Baselines in Data-Scarce Space Biology

Alireza Hayati, Jian Gong, Vaishnavi Nagesh…·Lauren Sanders

This paper benchmarks cross-species adaptation of a human retinal model to rodent OCT for age estimation, finding that CNN baselines outperform transformer models in small-sample settings.
