Let U andV be two unitary matrices. Consider the following statements:
Statement 1: U + V is unitary.
Statement 2: UV is unitary.
Select the correct options from the following:
Only statement 2 is correct.
Both statement 1 and statement 2 are incorrect.
Both statement 1 and statement 2 are correct.
Only statement 1 is correct.
Consider a function f(x, y) = x² + y² − 4x − 2y + 5. Using gradient descent algorithm, with an initial guess of (3, 2) and learning rate of 0.1, what will be the value of (x, y) after one iteration?
x = 3.2, y = 2.2
x = 3, y = 2
x = 1.8,y = 0.8
x = 2.8, y = 1.8
x = 40, y = 20
x = 20, y = 40
x = 30, y = 30
x = 0, y = 60
None of these
