| src/data_prep/node_features.py | |
| Replacement for the (duplicated, half-finished) Phase-3 node-feature code inside | |
| ``temporal_data.py``. It reproduces *exactly* the node tensors that the deprecated | |
| ``DynamicGraphBuilder`` (graph_builder.py) fed to ``BipartiteSAGEExtended``, using the | |
| same data sources and the same lookups in ``feature_lookups.py`` -- but aligned to the | |
| global node-id maps emitted by Phase 4 instead of the old per-snapshot LabelEncoders. | |
| It provides two entry points: | |
| build_node_features(...) -- Phase 3. Assembles and SAVES the five static node | |
| tensors (x_pol, pol_state, x_comp, comp_sec, comp_ind) | |
| plus a metadata sidecar. Must run AFTER Phase 4, because | |
| it aligns to src_id_map.npy / dst_id_map.npy. | |
| load_combined_graph(...) -- Recombines the per-year shards into ONE static graph | |
| (the yearly split was only to keep file sizes sane), | |
| converts the unified node ids back to the bipartite-local | |
| convention the model expects, loads the saved node | |
| tensors, and returns everything ready for the model. | |
| ------------------------------------------------------------------------------------ | |
| WHY THE OLD PHASE 3 WAS WRONG | |
| ------------------------------------------------------------------------------------ | |
| ``BipartiteSAGEExtended.forward`` needs five node tensors: | |
| x_pol [n_pol, pol_dim], pol_state [n_pol], | |
| x_comp [n_comp, comp_dim], comp_sec [n_comp], comp_ind [n_comp] | |
| The old Phase 3 produced free-floating committee/SEC parquets that were (a) never | |
| aligned to the node-id maps, (b) missing the categorical embedding indices entirely, | |
| and (c) reading from ad-hoc ``data/cropped`` paths instead of the config paths the | |
| lookups use. This module fixes all three. | |
| ------------------------------------------------------------------------------------ | |
| COMPOSITION (mirrors DynamicGraphBuilder, with your current config flags) | |
| ------------------------------------------------------------------------------------ | |
| x_pol (pol_dim = 42 with PERFORMANCE+BIO+IDEOLOGY+COMMITTEES, ECON off): | |
| [ win_rate, log_count, buy_ratio ] performance (3) | |
| [ chamber, party x4, is_leader ] bio = full_bio[:5]+[leader] (6) | |
| [ coord1D, coord2D ] ideology (2) | |
| [ committee one-hot ] committees (31) | |
| NB: the 56-dim state one-hot from PoliticianBioLookup is intentionally dropped -- | |
| state is carried as the learned `pol_state` embedding instead. | |
| x_comp (comp_dim = 10 with COMPANY_SIC, FINANCIALS off): | |
| [ SIC-division one-hot ] (10) | |
| Categoricals (from the transactions CSV, NOT the lookups -- matches the old | |
| get_categorical_ids snippet): | |
| pol_state <- dominant `State` per BioGuideID, label-encoded | |
| comp_sec <- dominant `Sector` per Ticker, label-encoded | |
| comp_ind <- dominant `Industry`per Ticker, label-encoded | |
| Index 0 of every categorical vocabulary is reserved for "UNK" so that nodes which only | |
| appear in structural edges (and therefore have no transaction row) get a valid index. | |
| Snapshot policy: time-varying lookups are evaluated as-of the LAST event date in the | |
| window (per your call). Performance stats are aggregated over the full window, exactly | |
| as the deprecated builder did. | |
