Which of the following options is an example of the concept of overfitting?
Choose ONE option (1 out of 4)

• A.A model for the recognition of dogs was trained predominantly with pictures of dogs in parks. On pictures with other animals in parks, dogs are also falsely recognized.
• B.A model for predicting IT system failures delivers too many false-negative predictions because the failures cannot be adequately explained via the log files used for training.
• C.A model for predicting academic performance was trained with data from students at one university.
  The model shows low predictive accuracy when applied to other universities.
• D.A previously trained model for recognizing cars is adapted and extended so that it can also identify the make of the car beyond its original function.

"AllerEgo" is a product that uses sell-learning to predict the behavior of a pilot under combat situation for a variety of terrains and enemy aircraft formations. Post training the model was exposed to the real- world data and the model was found to be behaving poorly. A lot of data quality tests had been performed on the data to bring it into a shape fit for training and testing.
Which ONE of the following options is least likely to describes the possible reason for the fall in the performance, especially when considering the self-learning nature of the Al system?
SELECT ONE OPTION

• A.The difficulty of defining criteria for improvement before the model can be accepted.
• B.There was an algorithmic bias in the Al system.
• C.The unknown nature and insufficient specification of the operating environment might have caused the poor performance.
• D.The fast pace of change did not allow sufficient time for testing.

Which ONE of the following statements provides the BEST description of the AI effect?

• A.AI systems increasingly behave like humans
• B.As AI systems improve, the likelihood of reaching the technological singularity increases.
• C.The systems used to play chess against human experts in the 1990's are no longer considered AI.
• D.AI systems get better over time as they are exposed to more data.

Which ONE of the following options is an example that BEST describes a system with Al-based autonomous functions?
SELECT ONE OPTION

• A.A fully automated manufacturing plant that uses no software.
• B.A system that utilizes a tool like Selenium.
• C.A system that utilizes human beings for all important decisions.
• D.A system that is fully able to respond to its environment.

Which ONE of the following statements is a CORRECT adversarial example in the context of machine learning systems that are working on image classifiers.
SELECT ONE OPTION

• A.These attack examples cause a model to predict the correct class with slightly less accuracy even though they look like the original image.
• B.These examples are model specific and are not likely to cause another model trained on same task to fail.
• C.These attacks can't be prevented by retraining the model with these examples augmented to the training data.
• D.Black box attacks based on adversarial examples create an exact duplicate model of the original.
