AI Anomaly Detection Quiz

Mhinduro uye tsananguro zvinoonekwa paunenge uchitora bvunzo.

1. Sei kuwonekwa kweanomaly kuchiwanzoshanda pasina mienzaniso yakanyorwa yezvisinganzwisisike?
   • Anomalies haawanzo uye haafungidzike, saka modhi dzinodzidza 'zvakajairika' panzvimbo
   • Mazita haabvumidzwe kushandiswa
   • Anomalies haamboitike
   • Inoshandisa mifananidzo chete
2. A 'contextual anomaly' inzvimbo yedata inoti:
   • Nguva dzose zvisizvo kwose kwose
   • Zvakajairika mune imwe mamiriro asi zvisina kujairika mune imwe
   • A typo mune dhatabhesi
   • A duplicate rekodhi
3. What does the cited WACV autoencoder study use as an anomaly score?
   • A legal fraud label assigned to every record
   • A guarantee that no future fault will occur
   • Reconstruction error from an autoencoder trained to model the data
   • The number of random trees in an Isolation Forest
4. How does the original Isolation Forest paper isolate candidate anomalies?
   • It requires an expert to label every anomaly in advance
   • It measures reconstruction error from a neural decoder
   • It uses a fixed threshold that proves an item is defective
   • Random partitioning tends to isolate anomalous instances in fewer splits
5. Ndeipi njodzi huru yekumisa chikumbaridzo chinosanzwisisika zvakanyanya?
   • Vanoongorora vanozadzwa nema alarm enhema
   • Iyo modhi inomhanya nekukurumidza
   • Data inovharwa
   • Anomalies inova isingagoneki
6. What can an unusual machine-vibration score reasonably trigger?
   • An automatic shutdown because failure is guaranteed
   • A maintenance investigation or additional measurement, without predicting failure with certainty
   • A confirmed diagnosis of the failed component
   • A claim that the machine will fail within a fixed number of hours
7. Why is an anomaly score not automatically a fraud or defect label?
   • It is always a verified label
   • Anomaly scores cannot be compared
   • It indicates unusualness under a model or baseline, not the cause or consequence
   • The threshold proves intent
8. What should be documented when setting an anomaly threshold?
   • Only the model’s name
   • A claim that false positives are impossible
   • The number of GPUs alone
   • The reference data, score definition, threshold rationale, and review process
