Bagging, also known as bootstrap aggregation, is an ensemble learning technique that combines the benefits of bootstrapping and aggregation to yield a stable model and improve the prediction performance of a machine-learning model.. In bagging, we first sample equal-sized subsets of data from a dataset with bootstrapping, i.e., we …

Dynamo's predictions for what would have happened to each sequenced cell matched what …
