Suppose you are developing an anomaly detection system to catch manufacturing defects in airplane engines. You model uses p(x) = p(x); μ. στ). You have two features.x₁ = vibration intensity, and x2 = heat generated. Both Xx₁ and X2 take on values between 0 and 1 (andare strictly greater than 0), and for most "normal" engines you expect that XX₂. One of the suspected anomalies is that a flawed engine may vibrate very intensely even without generating much heat (large X₁, small x2), even though the particular values of x₁ and may not fall outside their typical ranges of values. What additional feature x3 should you create to capture these types of anomalies:
(1) X3 = XXX2
(Ⅲ)X = X + Xxx
(II) X3XXX2
(IV)X3=
E35
