BilayerWS2(**overrides)

small 4-D STEM dataset of a bilayer WS2.

CuZnEELSMapping(**overrides)

An EELS spectrum image of copper and zinc oxide deposited on carbon nanotubes, used by the eXSpy elemental mapping tutorial.

CuZnHAADF(**overrides)

The HAADF survey image acquired simultaneously with the CuZnEELSMapping spectrum image - copper and zinc oxide on carbon nanotubes.

DE_CenterNet(**overrides)

Center refinement for DE SpotNet detections: segments each detected disk in a window of the raw pattern at native resolution and takes the coverage centroid, with a sigma head giving a positional uncertainty.

DE_CenterNet_Torch(**overrides)

Center refinement for DE SpotNet detections: segments each detected disk in a window of the raw pattern at native resolution and takes the coverage centroid, with a sigma head giving a positional uncertainty.

DE_FriedelNet(**overrides)

Friedel-partner center refinement, applied after DE CenterNet: reads each disk's window together with the 180-degree-rotated window at its Friedel mirror point, so it sees both dynamical fills of g and -g.

DE_FriedelNet_Torch(**overrides)

Friedel-partner center refinement, applied after DE CenterNet: reads each disk's window together with the 180-degree-rotated window at its Friedel mirror point, so it sees both dynamical fills of g and -g.

DE_SpotNet(**overrides)

Direct Electron's neural-network diffraction spot (Bragg disk) detector for 4D-STEM and scanning precession electron diffraction, the default detector in SpyDE, pyxem and quantem.

DE_SpotNet_Base16(**overrides)

Earlier edge-trained DE SpotNet detector, kept as a fallback.

DE_SpotNet_Base16_Torch(**overrides)

Earlier edge-trained DE SpotNet detector, kept as a fallback.

DE_SpotNet_Dynamical(**overrides)

DE SpotNet fine-tuned on multislice (dynamical) disks with counted and integrating detector noise, then self-trained on real 4D-STEM frames whose labels are persistence- and Friedel- verified.

DE_SpotNet_Dynamical_Torch(**overrides)

DE SpotNet fine-tuned on multislice (dynamical) disks with counted and integrating detector noise, then self-trained on real 4D-STEM frames whose labels are persistence- and Friedel- verified.

DE_SpotNet_Production(**overrides)

DE SpotNet variant with short-range-order augmentation and an edge-decoupled head; slightly higher recall on crystalline 4D-STEM at the canonical disk size, weaker off its trained scale.

DE_SpotNet_Production_Torch(**overrides)

DE SpotNet variant with short-range-order augmentation and an edge-decoupled head; slightly higher recall on crystalline 4D-STEM at the canonical disk size, weaker off its trained scale.

DE_SpotNet_Torch(**overrides)

Direct Electron's neural-network diffraction spot (Bragg disk) detector for 4D-STEM and scanning precession electron diffraction, the default detector in SpyDE, pyxem and quantem.
