The question is detailled and explained in the picture attached 3. Suppose we have four training examples under the two-category case, i.e.D* = {(x;, wi) | 1 ≤ i ≤ 4} where x₁ = (1, 2), x₂=(2, 2)*, x3 = (1, 1)²,x₁ = (2,0) and w₁ = W₂ = -1₁ W3 = ₁ = 1. Furthermore, linear discriminantfunction g(x) = w²x+b is adopted to learn from the training examples and thecriterion function to be minimized is set as J(w, b) = -₁₁ · g(xi).Given the initial model wo = (-2,2)' and bo = -3. If gradient descenttechniques are utilized to minimize the criterion function, what is the resultingdiscriminant function after three gradient descent steps with learning rate n = 0.1and threshold € = = 10-67

In this scenario, tasked with employing gradient descent techniques to minimize a criterion function…

Suppose a biking environment consists of n ≥ 3 landmarks,which are linked by bike route in a cyclical manner. That is, thereis a bike route between landmark 1 and 2, between landmark 2 and 3,and so on until we link landmark n back to landmark 1. In the centerof these is a mountain which has a bike route to every single landmark.Besides these, there are no other bike routes in the biking environment.You can think of the landmarks and the single mountain as nodes, andthe bike routes as edges, which altogether form a graph G. A path is asequence of bike routes.What is the number of paths of length 2 in the graph in termsof n?What is the number of cycles of length 3 in the graph in termsof n?What is the number of cycles in the graph in terms of n?

Consider the following equation that defines the conditions under which a square is breezy in the Wumpus World: ∀x,y Breezy(x, y) ⇔ ∃u,v Adjacent(u, v, x, y)∧Pit(u, v). Here we consider two other ways to describe this aspect of the Wumpus World. We can write diagnostic rulesleading from observed effects to hidden causes. For finding pits, the obvious diagnostic rules say that if a square is breezy, some adjacent square must contain a pit; and if a square is not breezy, then no adjacent square contains a pit. Write these two rules in first-order logic and show that their conjunction is logically equivalent to equation above. We can write causal rulesleading from cause to effect. One obvious causal rule is that a pit causes all adjacent squares to be breezy. Write this rule in first-order logic, explain why it is incomplete compared to equation above, and supply the missing axiom.
Design and explain a generic m-round winner tournament, Round-Winner-Tournament(P,m), for players P, in which the participants are matched randomly in each round 0, 1,...,m 1, and the winners advance to the next round. Following round m 1, the champion is chosen at random from among the remaining participants. This tournament structure, interestingly, contains the following special cases: m = 0 is a random selection tournament, m = 1 is a random pairing tournament, and m = lg |P| is a single elimination seeding tournament.
A statement form is satisfiable if there is an assignment True/False for its variables such that the statement form is True. Otherwise, that is, if no such assignment exists, the statement form is called unsatisfiable. Consider the statement form = (p → q) ^ (~ p V r) ^ (qV ~ r) Use a possibility tree to decide if is satisfiable or not.
Let P(x) and Q(x) be predicates and suppose D is the domain of x. For the statement forms in the given pair, determine whether they have the same truth value for every choice of P(x), Q(x), and D, or whether there is a choice of P(x), Q(x), and D for which they have opposite truth values. ∃x ∈ D, (P(x) ∧ Q(x)) and (∃x ∈ D, P(x)) ∧ (∃x ∈ D, Q(x))
