slip_gp_fit — DRIVE roverslip op

• Data kinds: signal × signal → table

• Call: import fullseye as fs; fs.ledger.slip_gp_fit(slopes, slips, length_scales=None, noise_levels=None) -> 'dict' (to call the implementation directly, import roverslip; roverslip.slip_gp_fit(slopes, slips, length_scales=None, noise_levels=None) -> 'dict'; from the registry, opsdrive.get("slip_gp_fit"))

Usage

Gaussian process from slope angle to slip ratio (RBF kernel + homoscedastic observation noise). Hyperparameters by grid search on the log marginal likelihood.

> The detailed description below is the original text — the summary and the headings are translated.

y は平均を引いて標準偏差で割ってから当てはめる(信号の分散 σ_f² = 1 に固定、ℓ と雑音 σ_n を探す)。length_scales の既定は角の範囲の 0.05〜2 倍の 16 段(対数)、noise_levels は 0.01〜1(正規化した y の単位)の 16 段。返り値は予測に使う dict(kind = "gp"、x・alpha・L・ell・noise・y_mean・y_scale・ log_marginal_likelihood)。雑音が角によって変わる(異分散)データでは、帯は全体の平均の幅になる(門の罠)。
