Jawaabaha iyo sharraxaadaha waxay soo baxayaan markaad qaadanayso kediska.

  1. Shabakadda neerfaha noocee ah ayaa aasaas u ahayd falanqaynta sawirrada caafimaadka?
    • Shabakadaha neerfaha ee Convolutional (CNNs)
    • Shabakadaha soo noqnoqda ee maqalka
    • Go'aan geedaha
    • Makrorada xaashida
  2. Muxuu qabtaa nidaamka Viz.ai?
    • Jadwalka cuntada ee kafateeriyada isbitaalka
    • Wuxuu falanqeeyaa CT scans si uu u calaamadiyo tuhunka istaroogga weelka weyn ee looga shakisan yahay oo kooxda u diga
    • Wuxuu u tarjumaa warbixinnada shucaaca muusiga
    • Beddelayaa qalabka CT scanner
  3. Waa maxay qaabka U-Net ee inta badan loo isticmaalo sawir-qaadista?
    • Soo saarista erayada heesta
    • Cadaadiska ciyaaraha fiidiyowga
    • Kala qaybinta per-pixel, sida qeexida buro ama xubin
    • Sirin sirta ereyada bukaanka
  4. What regulatory pathway did FDA use for the named Viz.ai imaging device?
    • A blanket approval covering all imaging-AI tools
    • A drug marketing authorization
    • An exemption from all clinical evidence requirements
    • A De Novo classification decision for a specific device and intended use
  5. Sababta ugu muhiimsan ee sawirka AI laga yaabo inuu ku guuldareysto xogta isbitaal cusub waa:
    • Farqiga u dhexeeya nooca scanner, borotokoolka, ama tirada bukaanka ee xogta tababarka
    • Sawiradu aad bay u midab badan yihiin
    • Qaabku ma jecla dhismaha
    • Sawiradu had iyo jeer waa isku mid meel kasta
  6. What do U-Net skip connections carry from the encoder to the decoder?
    • A patient’s medical record number
    • Higher-resolution feature maps that help recover spatial detail
    • A radiology report’s billing code
    • Only a global class label
  7. Why should medical-imaging datasets generally be split at the patient level?
    • To make every scanner appear in only one dataset
    • To guarantee equal disease prevalence
    • To reduce leakage from multiple correlated images of the same patient across train and test sets
    • To remove the need for external validation
  8. What does probability calibration assess in an imaging model?
    • Whether the scanner has been recently serviced
    • Whether every image has the same resolution
    • Whether the model segments the correct number of organs
    • Whether predictions assigned a probability match observed frequencies over evaluated cases
