Consider the minimax search scenario where it is agent A’s turn and the current state can be expanded in to states 1 and 2 where it is agent B’s turn. Each of those states can be expanded to 1.1, 1.2, 2.1, and 2.2, where it is again A’s turn. Now consider that each of those states can be expanded twice to the following eight states with corresponding evaluation scores from A’s evaluation function:1.1.1: 101.1.2: 51.2.1: 81.2.2: 92.1.1: 42.1.2: 52.2.1: 22.2.2: 9Consider lower numbered states are evaluated first. Which states would be pruned by alpha-beta minimax? give two answers.

Consider the following dataset including characteristics of houses and whether or not an agent was able to sell the house:   house color size      sold red large     yes red large     no gray small no gray large     yes gray small yes brown small no brown large     yes   If we were developing a naive bayes model to predict house sales, would it indicate that a small red house would be sold?  

Which is a model of the following:p ← q. q. r ← s.

Which machine learning technique does not produce a model that is a generalization of its input data (instead retains the individual inputs)?

If a machine learning model were predicting coronavirus infections and correctly diagnosed 50 patients with coronavirus, incorrectly diagnosed 22 patients with coronavirus, correctly declined to diagnose 500 patients with coronavirus, and missed diagnosing 200 patients with coronavirus when those patients were indeed ill with the disease, what is the precision of this model in this testing scenario?  

If a k-means algorithm was classifying the datapoint (2,2) and currently had cluster centroids (1,0), (2,4), and (4, 5) for clusters 1, 2, and 3 respectively, which cluster would the datapoint (2,2) be assigned to, assuming euclidean distance?

Planning is finding a sequence of to take from an initial state to arrive at a goal state.

In the context of an ontology, which of the following would be a “class”?

In the context of an ontology, what would be appropriate for the “domain” of a property “birthPlace”?

Consider the following datalog knowledge base:imm_west(r101,r103)imm_west(r103,r105)    imm_west(r105,r107)imm_east(E,W)←imm_west(W,E)next_door(E,W)←imm_east(E,W)next_door(W,E)←imm_west(W,E)Given this knowledge base, which of the following propositional queries would yield a ‘no’ answer?
