Nx-accelerated sensor fusion operations.

Replaces the pure-Elixir weighted averaging in Sensor.Fusion with vectorized Nx tensor operations. Only compiled when Nx is available as a dependency.

Summary

Functions

weighted_average(values_list, qualities)

Compute weighted average of sensor readings using Nx tensors.

@spec weighted_average([map()], [number()]) :: map()

Compute weighted average of sensor readings using Nx tensors.

Takes a list of value maps and a corresponding list of quality weights. Returns a single map of weighted-average values per key.

Vectorized: builds a [n_readings, n_keys] matrix and a [n_readings] weight vector, then computes the dot product in one pass.
