Rather than a randomized or full context of domain data points, a local context of data points is selected that is customized for a particular data query. The system uses a pre-trained model, such as a TabPFN, that is trained on a classification for different types of data sets along with a “context” for applying the model with the nearest neighbors of that data point. The number of neighbors may vary and may be determined based on the distance of data points to the query point. The system also optimizes fine-tuning of tabular data models with neighborhood data so that local context can be used to select training batches of data using a common context. This allows local context fine-tuning without excess training costs of single-item training batches.
