# ADR-071: ruvllm Training Pipeline for CSI Sensing Models
|
||||||
|
|
||||||
|
- **Status**: Proposed
|
||||||
|
- **Date**: 2026-04-02
|
||||||
|
- **Deciders**: ruv
|
||||||
|
- **Relates to**: ADR-069 (Cognitum Seed CSI Pipeline), ADR-070 (Self-Supervised Pretraining), ADR-024 (Contrastive CSI Embedding / AETHER), ADR-016 (RuVector Training Pipeline)
|
||||||
|
|
||||||
|
## Context
|
||||||
|
|
||||||
|
The WiFi-DensePose project needs a training pipeline to convert collected CSI data
|
||||||
|
(`.csi.jsonl` frames from ESP32 nodes) into deployable models for presence detection,
|
||||||
|
activity classification, and vital sign estimation.
|
||||||
|
|
||||||
|
Previous ADRs established the data collection protocol (ADR-070) and Cognitum Seed
|
||||||
|
inference target (ADR-069). What was missing was the actual training, refinement,
|
||||||
|
quantization, and export pipeline connecting raw CSI recordings to deployable models.
|
||||||
|
|
||||||
|
### Why ruvllm instead of PyTorch
|
||||||
|
|
||||||
|
| Criterion | ruvllm | PyTorch | ONNX Runtime |
|
||||||
|
|-----------|--------|---------|--------------|
|
||||||
|
| Runtime dependency | Node.js only | Python + CUDA + pip | C++ runtime |
|
||||||
|
| Install size | ~5 MB (npm) | ~2 GB (torch+cuda) | ~50 MB |
|
||||||
|
| SONA adaptation | <1ms native | N/A | N/A |
|
||||||
|
| Quantization | 2/4/8-bit TurboQuant | INT8/FP16 (separate tool) | INT8 only |
|
||||||
|
| LoRA fine-tuning | Built-in LoraAdapter | Requires PEFT library | N/A |
|
||||||
|
| EWC protection | Built-in EwcManager | Manual implementation | N/A |
|
||||||
|
| SafeTensors export | Native SafeTensorsWriter | Via safetensors library | N/A |
|
||||||
|
| Contrastive training | Built-in ContrastiveTrainer | Manual triplet loss | N/A |
|
||||||
|
| Edge deployment | ESP32, Pi Zero, browser | GPU servers only | ARM (limited) |
|
||||||
|
| M4 Pro performance | 88-135 tok/s native | ~30 tok/s (MPS) | ~50 tok/s |
|
||||||
|
| Ecosystem integration | RuVector, Cognitum Seed | Standalone | Standalone |
|
||||||
|
|
||||||
|
The ruvllm package (`@ruvector/ruvllm` v2.5.4) provides the complete training
|
||||||
|
lifecycle in a single dependency: contrastive pretraining, task head training,
|
||||||
|
LoRA refinement, EWC consolidation, quantization, and SafeTensors/RVF export.
|
||||||
|
No Python dependency means the entire pipeline runs on the same Node.js runtime
|
||||||
|
as the Cognitum Seed inference engine.
|
||||||
|
|
||||||
|
## Decision
|
||||||
|
|
||||||
|
Use ruvllm's `ContrastiveTrainer`, `TrainingPipeline`, `LoraAdapter`, `EwcManager`,
|
||||||
|
`SafeTensorsWriter`, and `ModelExporter` for the complete CSI model training lifecycle.
|
||||||
|
|
||||||
|
### Training Phases
|
||||||
|
|
||||||
|
The pipeline executes five sequential phases:
|
||||||
|
|
||||||
|
#### Phase 1: Contrastive Pretraining
|
||||||
|
|
||||||
|
Learns an embedding space where temporally and spatially similar CSI states are close
|
||||||
|
and dissimilar states are far apart.
|
||||||
|
|
||||||
|
- **Encoder architecture**: 8-dim CSI feature vector -> 64-dim hidden (ReLU) -> 128-dim embedding (L2-normalized)
|
||||||
|
- **Loss functions**: Triplet loss (margin=0.3) + InfoNCE (temperature=0.07)
|
||||||
|
- **Triplet strategies**:
|
||||||
|
- Temporal positive: frames within 1 second (same environment state)
|
||||||
|
- Temporal negative: frames >30 seconds apart (different state)
|
||||||
|
- Cross-node positive: same timestamp from different ESP32 nodes (same person, different viewpoint)
|
||||||
|
- Cross-node negative: different timestamp + different node
|
||||||
|
- Hard negatives: frames near motion energy transition boundaries
|
||||||
|
- **Hyperparameters**: 20 epochs, batch size 32, hard negative ratio 0.7
|
||||||
|
- **Implementation**: `ContrastiveTrainer.addTriplet()` + `.train()`
|
||||||
|
|
||||||
|
#### Phase 2: Task Head Training
|
||||||
|
|
||||||
|
Trains supervised heads on top of the frozen embedding for specific sensing tasks.
|
||||||
|
|
||||||
|
- **Presence head**: 128 -> 1 (sigmoid), threshold at presence_score > 0.3
|
||||||
|
- **Activity head**: 128 -> 3 (softmax: still/moving/empty), derived from motion_energy thresholds
|
||||||
|
- **Vitals head**: 128 -> 2 (linear: breathing BPM, heart rate BPM), normalized targets
|
||||||
|
- **Implementation**: `TrainingPipeline.addData()` + `.train()` with cosine LR scheduler,
|
||||||
|
early stopping (patience=5), and quality-weighted MSE loss
|
||||||
|
|
||||||
|
#### Phase 3: LoRA Refinement
|
||||||
|
|
||||||
|
Per-node LoRA adapters for room-specific adaptation without forgetting the base model.
|
||||||
|
|
||||||
|
- **Configuration**: rank=4, alpha=8, dropout=0.1
|
||||||
|
- **Per-node training**: Each ESP32 node gets its own LoRA adapter trained on
|
||||||
|
node-specific data with reduced learning rate (0.5x base)
|
||||||
|
- **Implementation**: `LoraManager.create()` for each node, `TrainingPipeline` with
|
||||||
|
`LoraAdapter` passed to constructor
|
||||||
|
|
||||||
|
#### Phase 4: Quantization (TurboQuant)
|
||||||
|
|
||||||
|
Reduces model size for edge deployment with minimal quality loss.
|
||||||
|
|
||||||
|
| Bit Width | Compression | Typical RMSE | Target Device |
|
||||||
|
|-----------|-------------|-------------|---------------|
|
||||||
|
| 8-bit | 4x | <0.001 | Cognitum Seed (Pi Zero) |
|
||||||
|
| 4-bit | 8x | <0.01 | Standard edge inference |
|
||||||
|
| 2-bit | 16x | <0.05 | ESP32-S3 feature extraction |
|
||||||
|
|
||||||
|
- **Method**: Uniform affine quantization with scale/zero-point per tensor
|
||||||
|
- **Quality validation**: RMSE between original fp32 and dequantized weights
|
||||||
|
|
||||||
|
#### Phase 5: EWC Consolidation
|
||||||
|
|
||||||
|
Elastic Weight Consolidation prevents catastrophic forgetting when the model
|
||||||
|
is later fine-tuned on new room data or updated CSI conditions.
|
||||||
|
|
||||||
|
- **Fisher information**: Computed from training data gradients
|
||||||
|
- **Lambda**: 2000 (base), 3000 (per-node)
|
||||||
|
- **Tasks registered**: Base pretraining + one per ESP32 node
|
||||||
|
- **Implementation**: `EwcManager.registerTask()` for each training phase
|
||||||
|
|
||||||

|

|
|
||||||
|
## Consequences
|
||||||
|
|
||||||
|
### Positive
|
||||||
|
|
||||||
|
- **Zero Python dependency**: The entire training and inference pipeline runs on
|
||||||
|
Node.js, eliminating Python/CUDA/pip dependency management on training and
|
||||||
|
deployment targets.
|
||||||
|
- **Integrated lifecycle**: Contrastive pretraining, task heads, LoRA refinement,
|
||||||
|
EWC consolidation, and quantization in a single script using one library.
|
||||||
|
- **Edge-first**: 2-bit quantization enables running the encoder on ESP32-S3.
|
||||||
|
4-bit quantization fits comfortably on Cognitum Seed Pi Zero.
|
||||||
|
- **Continual learning**: EWC protection means the model can be updated with new
|
||||||
|
room data without losing previously learned patterns.
|
||||||
|
- **Per-node adaptation**: LoRA adapters allow room-specific fine-tuning with
|
||||||
|
minimal storage overhead (rank-4 adapter ~2KB per node).
|
||||||
|
- **HuggingFace compatibility**: SafeTensors export enables sharing models on the
|
||||||
|
HuggingFace Hub and loading in other frameworks.
|
||||||
|
- **Reproducibility**: Seeded encoder initialization and deterministic data pipeline
|
||||||
|
ensure reproducible training runs.
|
||||||
|
|
||||||
|
### Negative
|
||||||
|
|
||||||
|
- **No GPU acceleration**: ruvllm's JS training loop does not use GPU compute.
|
||||||
|
For the small model sizes in CSI sensing (8->64->128), this is acceptable
|
||||||
|
(~seconds on M4 Pro), but would not scale to large vision models.
|
||||||
|
- **Simplified backpropagation**: The LoRA backward pass and contrastive training
|
||||||
|
use approximate gradient updates rather than full automatic differentiation.
|
||||||
|
Sufficient for the target model sizes but not equivalent to PyTorch autograd.
|
||||||
|
- **Quantization is post-training only**: No quantization-aware training (QAT).
|
||||||
|
For 4-bit and 8-bit this produces acceptable quality loss; 2-bit may need
|
||||||
|
QAT in future if quality degrades.
|
||||||
|
|
||||||
|
### Risks
|
||||||
|
|
||||||
|
- **Quality ceiling**: The simplified training may produce lower accuracy than a
|
||||||
|
PyTorch-trained equivalent. Mitigated by: (a) the model is small enough that
|
||||||
|
the training loop converges quickly, (b) SONA adaptation can compensate at
|
||||||
|
inference time, (c) we can switch to PyTorch for training only if needed
|
||||||
|
while keeping ruvllm for inference.
|
||||||
|
- **ruvllm API stability**: The library is at v2.5.4 with active development.
|
||||||
|
Mitigated by vendoring the package in `vendor/ruvector/npm/packages/ruvllm/`.
|
||||||
|
|
||||||
|
## Implementation
|
||||||
|
|
||||||
|
