🎯 Belief Space (f, c)
Click anywhere on the canvas to place a belief. The truth value (f, c) is determined by your click position: x-axis = frequency, y-axis = confidence.
📐 NAL Revision Formula
// Given two beliefs B1(f1,c1) and B2(f2,c2) with evidence weights w1, w2:
// w1 = c1 / (1 - c1), w2 = c2 / (1 - c2)
// f = (f1*w1 + f2*w2) / (w1 + w2)
// c = (w1 + w2) / (w1 + w2 + 1)
//
// The merged belief accumulates evidence — confidence grows toward 1.0
// as more evidence is gathered, while frequency converges to the
// evidence-weighted average.
Try adding multiple beliefs with similar frequencies — watch confidence climb. Add contradictory evidence to see frequency shift.
