Evolution of approximation for purple-highlighted elements in Fig. 2B, using DG-IST with d = opt = 171 (left panel) and DG-IST with d = inf (right panel).

Abstract

<p>First row of each panel shows the approximation evolution of the two elements, black horizontal lines declare the original elements to be approximated and vertical pink lines (only left panel) show the iterations at which elimination of inhibition takes place for the second largest element in the corresponding column of <i>x<sup>m</sup></i>. The second row of each panel illustrates the Input to each GC through the iterative process, <math><mrow><mi>i</mi><mi>n</mi><mi>p</mi><mi>u</mi><mi>t</mi><mo>=</mo><mi>κ</mi><mo>⋅</mo><mrow><mo>[</mo><mrow><mrow><mrow><mo>(</mo><mrow><mi>A</mi><mi>T</mi><mrow><mo>(</mo><mrow><mi>y</mi><mo>−</mo><mi>A</mi><msubsup><mi>x</mi><mi>i</mi><mi>m</mi></msubsup></mrow><mo>)</mo></mrow></mrow><mo>)</mo></mrow></mrow><mi>m</mi><mo>−</mo><msub><mi>I</mi><mi>s</mi></msub><mo>−</mo><msub><mi>M</mi><mi>s</mi></msub></mrow><mo>]</mo></mrow><mo>=</mo><mi>κ</mi><mo>⋅</mo><mo stretchy="false">(</mo><mi>E</mi><mi>r</mi><mi>r</mi><mi>o</mi><mi>r</mi><mo>+</mo><mi>I</mi><mi>N</mi><mi>T</mi><mo>+</mo><mi>M</mi><mi>C</mi><mo stretchy="false">)</mo></mrow></math>. The Error, MC, and INT values that add up to form the Input value are shown in the remaining rows of each panel.</p
