Idanwo Didinku Sharpness-Aware

Checks SAM’s two-pass update, its neighborhood radius, the perturbed-weight gradient and the trade-off between flatness and compute.

  1. Iru kere wo ni SAM gbiyanju lati wa?
    • O kere alapin nibiti pipadanu duro kekere kọja agbegbe ti awọn iwuwo
    • O kere julọ ti o ṣeeṣe
    • Awọn kere pẹlu awọn julọ sile
    • Eyikeyi o kere de ọdọ ni igbesẹ kan
  2. Bawo ni ọpọlọpọ siwaju-sẹhin kọja ni igbesẹ SAM boṣewa nilo?
    • Idaji kọja
    • O fẹrẹ to meji
    • Gangan ọkan
    • Mẹwa tabi diẹ ẹ sii
  3. Kini iṣakoso hyperparameter rediosi rho ni SAM?
    • Iyara ibajẹ ẹkọ
    • Awọn nọmba ti ikẹkọ epochs
    • Iwọn agbegbe ni ayika awọn iwuwo ti o ni aabo lodi si awọn spikes pipadanu
    • Awọn iṣeeṣe dropout
  4. Kini akọkọ ti awọn igbesẹ meji SAM ni aṣetunṣe kọọkan?
    • Din awoṣe
    • Apapọ awọn iwuwo ti gbogbo awọn ti o ti kọja awọn igbesẹ
    • Tun ipo oluṣeto
    • Ṣe igbesẹ gigun ti iwọn rho si aaye ti o buruju ti o wa nitosi
  5. Kini idi ti SAM nigbagbogbo ṣe ilọsiwaju agbara lati ṣe aami ariwo?
    • Nitoripe minima alapin ko ni itara lati ṣe akori awọn akole ibaje
    • Nitoripe o npa awọn aami alariwo rẹ laifọwọyi
    • Nitoripe o nlo awọn ọrọ ti o tobi ju
    • Nitori ti o meteta awọn ipele iwọn
  6. Ewo ninu iwọnyi jẹ iyatọ ti a ṣe lati dinku idiyele iṣiro SAM?
    • ReLU
    • ESAM (SAM ti o munadoko)
    • BatchNorm
    • AdaGrad
  7. In SAM’s second pass, which gradient is used to update the original model weights?
    • The gradient of a random label
    • The first pass gradient without evaluating the perturbed point
    • The gradient evaluated at the perturbed nearby weights
    • A gradient from a different model checkpoint
  8. If SAM’s neighborhood radius rho is set to zero, what happens to its perturbation step?
    • The model parameters are all set to zero
    • The loss becomes independent of the weights
    • The optimizer takes an infinite step
    • There is no weight perturbation, so the neighborhood reduces to the current point
