Fuzzy logic<\/strong> lets values be partially true \u2014 not only 0 or 1. It is useful when human labels like \u201cwarm\u201d or \u201cfast\u201d are vague but still actionable (thermostats, washing machines, recommendation scores).<\/p>\n

    1. Crisp vs fuzzy<\/strong><\/p>\n

      \n
    • Crisp:<\/strong> temp \u2265 25 \u21d2 hot, else not hot.<\/li>\n
    • Fuzzy:<\/strong> at 24\u00b0C you might be 0.7 \u201cwarm\u201d and 0.3 \u201chot\u201d.<\/li>\n<\/ul>\n

      2. Membership functions<\/strong><\/p>\n

      A membership function \u03bc(x) maps input x to [0, 1]. Common shapes: triangle, trapezoid, Gaussian.<\/p>\n

      def triangle(x, a, b, c):\n    if x <= a or x >= c: return 0.0\n    if x == b: return 1.0\n    if x < b: return (x - a) \/ (b - a)\n    return (c - x) \/ (c - b)\n<\/code><\/pre>\n
      3. Temperature example<\/strong><\/p>\n
      def cold(t): return triangle(t, 0, 10, 20)\ndef warm(t): return triangle(t, 15, 25, 35)\ndef hot(t):  return triangle(t, 30, 40, 50)\n\nt = 28\nprint(cold(t), warm(t), hot(t))\n<\/code><\/pre>\n
      4. Fuzzy rules (IF\u2013THEN)<\/strong><\/p>\n
      Example: IF temperature is hot AND humidity is high THEN fan_speed is fast. Engines combine rule strengths (min\/max or product) then defuzzify<\/strong> to a crisp output (centroid is common).<\/p>\n
      5. Where it shows up<\/strong><\/p>\n
      Control systems, games (NPC \u201caggression\u201d), and scoring pipelines. For most business apps, start with clear thresholds; use fuzzy logic when experts literally speak in grades of truth.<\/p>\n","protected":false},"excerpt":{"rendered":"
