Discussion and exercises:Chapter 5:· Discussion 1: What is an artificial neural network and for what types of problems can it be used?· Discussion 2: Compare artificial and biological neural networks. What aspects of biological networks are not mimicked by artificial ones? What aspects are similar?· Discussion 3: What are the most common ANN architectures? For what types of problems can they be used?· Discussion 4: ANN can be used for both supervised and unsupervised learning. Explain how they learn in a supervised mode and in an unsupervised mode.· Exercise 6: Go to Google Scholar (scholar.google.com). Conduct a search to find two papers written in the last five years that compare and contrast multiple machine-learning methods for a given problem domain. Observe commonalities and differences among their findings and prepare a report to summarize your understanding.Chapter 6· Discussion 1: What is deep learning? What can deep learning do that traditional machine-learning methods cannot?· Discussion 2: List and briefly explain different learning paradigms/ methods in AI.· Discussion 3: What is representation learning, and how does it relate to machine learning and deep learning?· Discussion 4: List and briefly describe the most commonly used ANN activation functions.· Discussion 5: What is MLP, and how does it work? Explain the function of summation and activation weights in MLP-type ANN.· Exercise 4: Cognitive computing has become a popular term to define and characterize the extent of the ability of machines/computers to show intelligent behavior. Thanks to IBM Watson and its success on Jeopardy!, cognitive computing and cognitive analytics are now part of many real- world intelligent systems. In this exercise, identify at least three application cases where cognitive computing was used to solve complex real-world problems. Summarize your findings in a professionally organized report.Your paper should meet these requirements:· Minimum 5 pages length, not including the required cover page and reference page. Also do not include questions, just number and the answer.· Follow APA 7 guidelines. Your paper should include an introduction, a body with fully developed content, and a conclusion.· Support your answers with the readings from the course and at least two scholarly journal articles to support your positions, claims, and observations.
