| # FELA-PdM playground |
|
|
| Feed a sensor window and see the model's call. Two tabs: remaining useful life (C-MAPSS, 30 |
| cycles of 14 sensors) and bearing fault (CWRU, 2048 vibration samples). Runs on CPU. |
|
|
| ## The demo data (and why it shows generalization) |
|
|
| The remaining useful life head was trained on C-MAPSS subset FD001 (a single operating |
| condition). The other subsets, FD002, FD003, and FD004, use different operating conditions and |
| fault modes and were not in this head's training set, so a window from those subsets is a real |
| out of distribution test. They are public NASA data from the Prognostics Data Repository |
| (Saxena et al. 2008); download a window and paste it into the RUL tab. |
|
|
| The bundled examples (the synthetic RUL window and the synthetic vibration window) are clearly |
| labeled as synthetic and illustrative. They let the Space load fast without a large download. |
| They are not real measurements and should not be read as benchmark results. |
|
|
| ## Weights |
|
|
| Set `FELA_PDM_WEIGHTS` (or a Space secret) to a directory holding the per head safetensors |
| (`cmapss_FD001.safetensors`, `cwru.safetensors`) and `config.json`. The weights are in the |
| Hugging Face repo `lowdown-labs/FELA-pdm`. |
|
|
| ## Note |
|
|
| For research and illustration only. This is not a safety critical controller. Do not act on the |
| remaining useful life number without independent validation against your own field data. |
