Researchers have developed a new method called observed-block multi-prediction for statistical data fusion, which allows for training Deep Boltzmann Machines (DBMs) even when no single data point observes all outcomes. This approach restricts the multi-prediction objective to observable targets, making it applicable to various missingness patterns. Experiments on consumer panels demonstrated that fine-tuned DBMs consistently outperformed fifteen other methods across different sample sizes and covariate widths, with the primary advantage stemming from conditioning on one outcome block to predict another, rather than from generative pre-training.
