Exam AWS Certified Machine Learning - Specialty topic 1 question 57 discussion

A Machine Learning Specialist is required to build a supervised image-recognition model to identify a cat. The ML Specialist performs some tests and records the following results for a neural network-based image classifier:
Total number of images available = 1,000
Test set images = 100 (constant test set)
The ML Specialist notices that, in over 75% of the misclassified images, the cats were held upside down by their owners.
Which techniques can be used by the ML Specialist to improve this specific test error?

  • A. Increase the training data by adding variation in rotation for training images.
  • B. Increase the number of epochs for model training
  • C. Increase the number of layers for the neural network.
  • D. Increase the dropout rate for the second-to-last layer.

NO CORRECT TRAINING DATA, MORE WORKS JUST WASTE TIME. ONE OF THE REASONS FOR POOR ACCURACY COULD BE INSUFFICIENT DATA. THIS CAN BE OVERCOME BY IMAGE AUGMENTATION. IMAGE AUGMENTATION IS A TECHNIQUE OF INCREASING THE DATASET SIZE BY PROCESSING (MIRRORING, FLIPPING, ROTATING, INCREASING/DECREASING BRIGHTNESS, CONTRAST, COLOR) THE IMAGES. HTTPS://MEDIUM.COM/DATADRIVENINVESTOR/AUTO-MODEL-TUNING-FOR-KERAS-ON-AMAZON-SAGEMAKER-PLANT-SEEDLING-DATASET-7B591334501E ANSWER A. ADD MORE TRAINING DATA FOR ROTATION IMAGES COULD BE A WAY TO DEAL WITH ISSUE

The key phrase might be "constant test set", so you can't increase training set by shrinking the size of test set. Thus the only feasible choice is to increase training time by increasing the number of epochs => answer B.

The problem is images are upside down and misclassified. If right side up then the model would classify correctly. This can only be fixed ba rotating not by trying to recognise upside down cat more times.

A . Increase the training data by adding variation in rotation for training images. It never says to move the images from Test data set (because it is constant)... only variations are added to the images..so, A is correct.

Selected Answer: A
the Specialist can apply data augmentation techniques to increase the training data by adding variation in rotation for training images. This technique will allow the model to learn to recognize cats in various orientations, including upside down.

Selected Answer: A
Adding more variation in rotation to the training data can help the model to learn how to classify cats in different orientations, including when they are held upside down. This can improve the model's ability to identify cats in this position and reduce the misclassification rate for images in which the cats are upside down. By adding more rotation to the training data, the model can be trained to generalize better to new images, including those with cats in different orientations. This can help to reduce overfitting and improve the model's overall performance.
