A1: using the nearest-neighbor spin glass model: We use a covariance matrix to calculate the principal components analysis (PCA). To fit the log-eigenvalues of PCA (blue), we use least-squares to find the optimize line (red). $\langle J\rangle$$\Delta J$$\Delta J$$\Delta J$$\alpha$$h$$J$$h$$J$$h$$J$$\langle J\rangle$$…
