…acebook#5200) Summary: Pull Request resolved: facebook#5200 Adds a `data_parameters` argument to `TorchAdapter._get_fit_args` that decouples SSD construction (model params) from data column extraction (target params). This lets the TL adapter set `_model_space` to include source-only RangeParameters directly, so the SSD naturally covers the full joint feature space -- eliminating the need for the `_expand_ssd_to_joint_space` post-hoc expansion. Overrides `_set_search_space` to add source-only RangeParameters from the joint search space to `_model_space` while preserving target bounds for shared params (Normalize stays anchored to target bounds). At gen time, `self.parameters` is temporarily swapped to target-only so `extract_search_space_digest` sees only params present in the gen-time search space. Deletes `_expand_ssd_to_joint_space` (~90 lines). Differential Revision: D104702983

facebook#5193) Summary: Switches the default heterogeneous transfer learning model from a specialized per-task kernel model to a standard multi-task GP with learned feature imputation. The previous default model class is marked as deprecated. Reviewed By: saitcakmak Differential Revision: D102197137

…acebook#5200) Summary: **Motivation:** model_space/search_space was not properly used - parameter bounds on the search space would be set from the union of source and target, and parameters that were fixed on the target would be RangeParameters if the model_space contained a Fixed/Range change in the parameter. Adds a `data_parameters` argument to `TorchAdapter._get_fit_args` that decouples SSD construction (model params) from data column extraction (target params). This lets the TL adapter set `_model_space` to include source-only RangeParameters directly, so the SSD naturally covers the full joint feature space -- eliminating the need for the `_expand_ssd_to_joint_space` post-hoc expansion.
