Curiosity driven learning using band excitation piezo-response spectroscopy (BEPS) data on lead titanate (PTO) samples.

This is the experimental data involving band excitation piezoresponse spectroscopy (BEPS) of lead titanate (PTO) samples. This data was acquired using band excitation piezoresponse force microscopy (BE-PFM). We use this data on curiosity driven algorithms to explore structure-spectral relationships using scanning probe microscopy.
