*Notes: Look at the illustration below to answer question: During the model training using a neural network, the performance log obtained resembles the illustration above. The conclusions that can be drawn based on the log performance plot are: a) Model indicated Underfitting b) Model indicated Overfitting c) The model is stuck in local optima d) The model is stuck in global optima

E Random Pub Crawl: Your town has 5 pubs close to your home, say A, B, C, D, E. 1/4 1/2 1/2 Home 1/2 1/4 1/4 1/4/ 1/4 1/4 1/3 1/4 1/2 1/3 1/4 D E 1/3 1/2 (a) Write a program to simulate the random pub crawl. (From the "home" state allow probability 1/2 of going back to state B). (b) Starting from the Home state, run your program 1000 times, each time simulating a Markov chain of length 100. Each simulation should output a random sequence of values ($1, 82, 83..., $100 ) where each si is a pub and with that sequence, compute the num- ber of times each state is visited. Keep only these statistics. After the 1000 repetitions compute the average number of visits to each state. 3.
