Suggested Parameter Renaming for Expressivity

Suggested Parameter Renaming

To improve clarity, some parameter names could be made more explicit:

• W → basis_weights: coefficients for Chebyshev basis functions
• U → sqrt_factor or cholesky_factor: the square-root factor used in covariance construction
• Sigmas → covariances: the covariance matrices themselves
• diag_term → min_variance or noise_floor: ensures numerical stability
• extra_dims → latent_dims: extra dimensions beyond stimulus dimensions
• variance_scale → prior_scale: prior variance for low-order coefficients
• decay_rate → smoothness_prior: controls smoothness across basis degrees
