Show HN: 引力追踪的不是质量，而是波形复杂度
2 分•作者: ordinarily•5 个月前
一个带宽受限的神经网络（我将其命名为Erebus），在公开的LIGO引力波数据上进行训练，发现持久性——即时间累积对预测结构有多大帮助——与波形的谱熵相关（r = +0.69，p = 2×10⁻⁵），而与质量无关（ρ = −0.05，p = 0.80）。两个质量相同的黑洞合并，其持久性差异可达100倍。这种差异完全由信号的谱复杂性解释，而非源的质量。这种模式在四种架构不同的观察者（GRU、LSTM、Transformer、ViT-Small）中均有体现。
一篇配套论文建立了框架：固定一个观测流程，并测量来自独立仪器（LIGO、EHT、CMB、太阳黑子、类星体、超新星、中微子）的13个真实数据域的持久性。单一的时间轴组织了所有域，电磁学位于一端，引力位于另一端。通过同一流程的周期性信号在180多次运行中产生零正持久性——当观测边界没有划分周期时，累积会破坏波。

A bandwidth-limited neural network (that I've named Erebus) trained on public LIGO gravitational wave data finds that persistence — how much temporal accumulation helps predict structure — correlates with spectral entropy of the waveform (r = +0.69, p = 2×10⁻⁵) and not with mass (ρ = −0.05, p = 0.80). Two black hole mergers at identical mass differ by 100× in persistence. The difference is entirely explained by the spectral complexity of the signal, not the mass of the source. The pattern reproduces across four architecturally distinct observers (GRU, LSTM, Transformer, ViT-Small).<p>A companion paper establishes the framework: fix an observation pipeline and measure persistence across 13 real-data domains from independent instruments (LIGO, EHT, CMB, sunspots, quasars, supernovae, neutrinos). A single temporal axis organizes all domains, with electromagnetism at one pole and gravity at the other. A periodic signal through the same pipeline produces zero positive persistence across 180+ runs — accumulation destroys the wave when observation boundaries don't divide the period.<p>First Paper: <a href="https://zenodo.org/records/19323952" rel="nofollow">https://zenodo.org/records/19323952</a>
