Question 18

+2 marksOne or more correct options

Which of the following statements are true? (Select all possible correct options)

Select all that apply.

  1. A

    Autoencoder are equivalent to Principal Component Analysis (PCA) provided we don’t use of non-linear activation functions

  2. B

    When using global attention on temporal data, alignment weights are learnt for encoder hidden representations for all time steps

  3. C

    Positional encoding is an important component of the transformer architecture as it conveys information about order in a given sequence

  4. D

    It is not possible to generate different captions for the same image that have similar meaning but different tone/style

  5. E

    Autoencoders can not be used for data compression as its input and output dimensions are different
