Which of the Following Statements A), B) or C) Is

question 50

Multiple Choice

Which of the following statements a) , b) or c) is false?

• A) Calling our MNIST cnn model's predict method as shown below predicts the classes of the digit images in its argument array (X_test):
• Predictions = cnn.predict(X_test)
• B) You can check what the first sample digit should be by looking at y_test[0]:
• [42]: y_test[0]
• [42]: array([0., 0., 0., 0., 0., 0., 0., 1., 0., 0.], dtype=float32)
• The one-hot encoding in the preceding output shows that the first sample is the digit 7.
• C) The following code outputs the probabilities returned by the predict method for the first test sample:
• [43]: for index, probability in enumerate(predictions[0]):
• Print(f'{index}: {probability:.10%}')​
• 0: 0.0000000201%
• 1: 0.0000001355%
• 2: 0.0000186951%
• 3: 0.0000015494%
• 4: 0.0000000003%
• 5: 0.0000000012%
• 6: 0.0000000000%
• 7: 99.9999761581%
• 8: 0.0000005577%
• 9: 0.0000011416%
• According to the preceding output, predictions[0] indicates that our cnn model believes this digit is a 7 with nearly 100% certainty. Not all predictions have this level of certainty.
• D) All of the above statements are true.

Definitions:

Pitch

The quality of a sound governed by the rate of vibrations producing it; the degree of highness or lowness of a tone.

Frequency

The rate at which a vibration occurs that constitutes a wave, either in a material (as in sound waves), or in an electromagnetic field (as in radio waves and light).

Sound Wave

A type of pressure wave generated by vibrating objects, traveling through mediums such as air, water, or solids, and perceived as sound by the human ear.

Müller-Lyer Illusion

A visual illusion in which two lines of the same length appear to be of different lengths because of the orientation of arrow-like tails at their ends.
