Figure 13From: Big data and deep data in scanning and electron microscopies: deriving functionality from multidimensional data setsRecognition of the shape of the ferroelectric domains. (a) Shape of the ferroelectric domains produced by application of the sequences of positive and negative electric pulses to the SPM tip. (b, c) Principal component analysis over experimental data set of 288 domains. (b) First 16 eigenvectors and (c) weights.Back to article page
