HyperSpy and SAMFire for big data analysis by Tomas Ostaševičius

Electron Microscopy data Tomas Ostaševičius

Multidimensional analysis Visualize Pre-process Analyse Machine-learning Non-linear fitting Python Open-source Actively developed www.hyperspy.org Tomas Ostaševičius

Traditional Fitting approach Spectral image Tomas Ostaševičius

SAMFire (Smart Adaptive Multi-dimensional Fitting) Use data to determine which pixel to fit next. Use all available information. Check if fit succeeds. Next Not fitted Fitted Tomas Ostaševičius

It works! Tomas Ostaševičius
