wifi-densepose-train

Complete training pipeline for WiFi-DensePose, integrated with all five ruvector crates.

Overview

wifi-densepose-train provides everything needed to train the WiFi-to-DensePose model: dataset loading, subcarrier interpolation, loss functions, evaluation metrics, and the training loop orchestrator. It supports both the MM-Fi dataset (NeurIPS 2023) and deterministic synthetic data for reproducible experiments.

Without the tch-backend feature the crate still provides the dataset, configuration, and subcarrier interpolation APIs needed for data preprocessing and proof verification.

Features

• MM-Fi dataset loader -- Reads the MM-Fi multimodal dataset (NeurIPS 2023) from disk with memory-mapped .npy files.
• Synthetic dataset -- Deterministic, fixed-seed CSI generation for unit tests and proofs.
• Subcarrier interpolation -- 114 -> 56 subcarrier compression via ruvector-solver sparse interpolation with variance-based selection.
• Loss functions (tch-backend) -- Pose estimation losses including MSE, OKS, and combined multi-task loss.
• Metrics (tch-backend) -- PCKh, OKS-AP, and per-keypoint evaluation with ruvector-mincut-based person matching.
• Training orchestrator (tch-backend) -- Full training loop with learning rate scheduling, gradient clipping, checkpointing, and reproducible proofs.
• All 5 ruvector crates -- ruvector-mincut, ruvector-attn-mincut, ruvector-temporal-tensor, ruvector-solver, and ruvector-attention integrated across dataset loading, metrics, and model attention.

Quick Start

use wifi_densepose_train::config::TrainingConfig;
use wifi_densepose_train::dataset::{SyntheticCsiDataset, SyntheticConfig, CsiDataset};

// Build and validate config
let config = TrainingConfig::default();
config.validate().expect("config is valid");

// Create a synthetic dataset (deterministic, fixed-seed)
let syn_cfg = SyntheticConfig::default();
let dataset = SyntheticCsiDataset::new(200, syn_cfg);

// Load one sample
let sample = dataset.get(0).unwrap();
println!("amplitude shape: {:?}", sample.amplitude.shape());
