Virtual Memory Review (1/2) °Caches are NOT mandatory: • Processor performs arithmetic • Memory stores data • Caches simply make things go faster °Each level of memory hierarchy is just a subset of next higher level °Caches speed up due to temporal locality: store data used recently °Block size > 1 word speeds up due […]

Logical and Shift Operations Overview °Logical Instructions ° Shifts Bitwise Operations (1/2) °Up until now, we’ve done arithmetic (add, sub,addi ), memory access (lw and sw), and branches and jumps. °All of these instructions view contents of register as a single quantity (such as a signed or unsigned integer) °New Perspective: View contents of register

3 – combinational logic 1 Jan. 18, 2016 In lectures 1 and 2, we looked at representations of numbers. For the case of integers, we saw that we could perform addition of two numbers using a binary representation and using the same algorithm that you used in grade school. I also argued that if you

Sample Questions For Term Test 2 Covers Backtracking Search and Uncertainty November 26, 2020 1. A latin square of size m is an m×m matrix containing the numbers 1–m such that no number occurs more than once in any row or column. For example 1234 4123 3412 2341 is a latin square of size 4.
Building/Assessing Bayes Net Models In the lecture notes we saw that in many real work examples it was possible to find conditional independencies/causations that allow us to construct good Bayes Net models. We can also use our understanding of causation/independence to critique different Bayes net models. Fahiem Bacchus, CSC384 Introduction to Artificial Intelligence, University of

follow the forward checking algorithm precisely: only prune values that would be pruned by the algorithm. GAC Example (c) Mark any node where a deadend occurs because of a domain wipe out (use the symbol DWO). 3. Say we have 4 variables X , Y , Z , and W , with the following domains
CSC384h: Intro to Artificial Intelligence 1 Fahiem Bacchus, University of Toronto } Reasoning Under Uncertainty This material is covered in chapters 13, 14. Chapter 13 gives some basic background on probability from the point of view of AI. Chapter 14 talks about Bayesian Networks, exact reasoning in Bayes Nets as well as approximate reasoning, which
