Task: Write Alphabet Forward-Backward Feature function: delta_smoothness #67
Description
Description
New functions are needed to compute forward-backward comparison metrics for the alphabet task. The delta_smoothness function will calculate the difference in smoothness (e.g., normalized jerk/SPARC proxy) between the forward (A→Z) and backward (Z→A) conditions.
Tasks
- Reuse or implement a smoothness helper that returns a scalar per condition
- Compute delta_smoothness = forward_smoothness - backward_smoothness
- Return the result as a float
