Dataset card: regenerated reports; the Nemotron alternative

README.md

@@ -29,3 +29,38 @@ The rest is supporting evidence: `verify/` (fall-alarm verdicts and clips),
 input). Face-recognition data is not published. Each room-1 report compares
 its routine with the earlier dates (day 1, the first, has none); day 19
 (room 2) has no baseline.
+
+The reports were regenerated on 2026-10-01 with the current report code
+(GitHub `feature/identity-linker`, commit `d4d52a1`: fall times read on the
+right clock, visit edges fitted to the detector, the get-up time after a
+fall, company the detector does not show removed, and other fixes). Only the
+language-model summary and report were re-run: the detector output, the
+fall-alarm verdicts (re-run: the same answers), the clips and the VLM segment
+summaries are the earlier run's, except that `verify/verdicts.json` now gives each confirmed fall's
+time on the video's own clock (`fall_time_absolute`). The report-generation
+times above are the earlier full runs'.
+
+## Alternative segment-summary VLM: Nemotron
+
+`results_nemotron/<video name>/` holds the same six days with Nemotron 3 Nano
+Omni 30B-A3B Reasoning (NVFP4) instead of Qwen as the segment-summary VLM
+and as the fall verifier; the language-model summary and report are the
+same Qwen3-8B. Made with GitHub branch `feature/vlm-variants` (commit
+`6bb2a45`), the stages `VERIFIER=nemotron MAP_VLM=nemotron bash
+bash/run_video_system.sh` runs, on the same detector output, alarm events and
+face-recognition data as `results/`. Each
+folder has `json_summary/` (the report and the VLM's per-segment answers),
+`verify/` (the alarm events and Nemotron's verdicts) and
+`action_classes.json`; detector files and clips are those of `results/`.
+
+| Six days | Qwen (`results/`) | Nemotron (`results_nemotron/`) |
+|---|---|---|
+| Real falls confirmed (of 2) / false falls | 2 / 0 | 2 / 0 |
+| Real visitors found (of 14) / extra people listed | 14 / 0 | 14 / 4 |
+| Resident's time in the room, mean error per day | 3.1 % | 5.8 % |
+| Resident's glasses described right (days) | 6 / 6 | 4 / 6 |
+
+Nemotron describes one person's clothes, glasses or hair differently from
+one 10-minute segment to the next, so a visitor can be listed twice
+(days 1, 6, 19) and part of the resident's day can appear as a visitor
+(day 8). Qwen remains the default.
