Question 8 of 62

A neural network is composed of a first affine transformation (affine1) followed by a ReLU non-linearity, followed by a second affine transformation (affine2).
Which two explicit functions are implemented by this neural network? (Choose two.)

y = affine1(ReLU(affine2(x)))

y = max(affine1(x), affine2(x))

y = affine2(ReLU(affine1(x)))

y = affine2(max(affine1(x), 0))

y = ReLU(affine1(x), affine2(x))

Correct Answer: C, D

Question 10 of 62

After importing a Jupyter notebook and CSV data file into IBM Watson Studio in the IBM Public Cloud project, it is discovered that the notebook code can no longer access the CSV file.
What is the most likely reason for this problem?

CSV files cannot be used as data sources in Watson Studio.

The CSV file was converted to a binary blob and must be converted in the notebook code.

The CSV file is stored in a Cloud Object Storage.

The CSV file is stored in a Watson Machine Learning instance and is only accessible via REST API.

Correct Answer: C
