""" EXP N (reviewer_response): MULTI-PROPERTY CONTINUOUS BOTTLENECK. Exp M trained a continuous bottleneck on a SINGLE property (restitution), producing PosDis 0.04-0.15 because PosDis is structurally low for single- attribute supervision. The discrete battery's PosDis 0.76 was on multi- property training. To make the comparison fair, train continuous codes on TWO properties (mass_bin + restitution_bin, both 3-class) with a 2-headed receiver, then measure multi-property PosDis. Architecture: same TemporalEncoder + multi-agent (4) ContinuousSender as Exp M. Receiver gets the concatenated continuous message and decodes BOTH properties via two parallel heads. Loss = sum of two CE losses. Iterated learning: 3 receivers, reset every 40 epochs. After training, compute multi-property metrics: - TopSim: Spearman corr between L2 message-distance and label-vector distance (concatenated [mass_bin, restitution_bin]). - PosDis (multi-prop): for each code dimension, MI with each property. PosDis = mean over dims of (top_MI - second_MI) / max(top_MI, eps). Range: [0, 1]. High = each dim specializes for one property. - CausalSpec: zero out each code dim, measure per-property accuracy drop. CausalSpec = max specialization across (dim, property) pairs. Cross-scenario eval on RESTITUTION only (mass is constant in ramp/flat).
