Band Power

A graph with columns at odd numbered frequencies 9 through 27 Hz.  Two groups of columns stand out, one centered around 11 Hz and the other around 23 Hz.  Each contains 4 or 5 columns.

Band Power Accuracy

On-line classification
~80% accuracy for all 3 subjects

Graph: Three different colored lines representing the percent accuracy for three subjects are plotted against session numbers 4 through 12.  The lines hover at about 80 percent accuracy with variations of as much as 10 percentage point from session to session.

Adaptive Autoregressive Parameters

Graph:  Three different colored lines representing the percent accuaracy for three subjects are plotted against session numbers 1 through 7.  All lines show a positive jump (from about 8 to 15 percentage points) between the first and second sessions.  They then hover between 80 and 95 percent with variations of 10 percentage points or less from session to session.

Common Spatial Patterns

Drawing and shaded graph.  The Drawing shows a head with 60 electrodes over it.  A 3 by 7 grid of electrodes centered around the Cz electrode and including the C3 and C4 electrodes is highlighted.  The shaded graph next to it represents 4 common spatial parameter weightings to be applied to data from the shaded electrodes to perform the classifications.  The first weighting is shaded light on the left and dark on the right while the other weighting in the pair is basically reversed.  The second weighting is is mostly dark while the other weighting in the pair is mostly light.
