XAI-exam questions

• curvillear distance gives the total amount of change between two points
• curvilinear distance depends on the particular algortihm used
• spatial distance difference between two time points
• lineair reduction techniques

  PCA, MDS
• non-lineair dimensionality reduction techniques : 


  t-SNE, UMAP, SOM
• UMAP is computationally faster then t-SNE
• Heatmaps 


  attribution, attention and saliency
• algortihms for attribution & feature visualisastion


  use one of the algorithms techniques to generate a new image of the same size taht either hightslis important regions (attribution) or is an entrily new image that is supposedly reprensative of the same calss (feature visualization)
