Evaluate the impact of an AI application used in the real world. (case study) : Working with X-Ray images: Case Study -

The video tutorial discusses building a model using Resnet, focusing on reusing previous work and making minor adjustments for image processing. It covers data preprocessing, including image scaling and augmentation, and explains the importance of conducting an ablation run to ensure the model functions correctly. The tutorial highlights issues of overfitting and accuracy, particularly in imbalanced datasets, and suggests using AUC for more reliable model evaluation. The video emphasizes the importance of understanding and adapting code for different projects.

What is the main change in the model setup compared to the previous project?

• Using a different neural network architecture

• Changing the image channel from three to one

• Increasing the number of epochs

• Switching from Resnet to VGG

Why is an ablation run performed in the model training process?

• To test the model's ability to generalize

• To reduce the model's complexity

• To ensure the model is running without errors

• To increase the model's accuracy

What is a potential reason for the drop in accuracy after an initial increase?

• The model architecture is too complex

• The data has a high class imbalance

• The learning rate is too high

• The model is overfitting to the training data

What metric is suggested as more reliable than accuracy in this context?

• AUC

• F1 Score

• Recall

• Precision

What does the ability of the model to overfit indicate?

• The model is learning the training data well

• The model is not suitable for the task

• The model is too simple

• The model needs more data
