In this tutorial, we’re going to learn about the cost function in logistic regression, and how we can utilize gradient descent to compute the minimum cost. 2. Logistic Regression. We use logistic regression to solve classification problems where the outcome is a discrete variable.

Instead of measuring the fluctuation of a single random variable, the covariance measures the fluctuation of two variables with each other. Recall that the variance is the mean squared deviation from the mean for a single random variable ...

Vector Product. A vector is an object that has both the direction and the magnitude. The length indicates the magnitude of the vectors, whereas the arrow indicates the direction. There are different types of vectors. In general, there are two ways of multiplying vectors. (i) Dot product of vectors (also known as Scalar product)

3 Answers. By expanding out the square, you can easily show that n ∑ i = 1(Xi − ˉX)2 = n ∑ i = 1X2i − nˉX2, using the fact that ∑ni = 1(Xi) = nˉX. So we need to calculate E[ n ∑ i = 1X2i] + E[nˉX2]. The first term, by the iid condition, is equal to nE[X2i]. Now note that Var(Xi) = E[X2i] − μ2, so E[X2i] = σ2 + μ2.

Unit Vector. A vector is a quantity that has both magnitude, as well as direction. A vector that has a magnitude of 1 is a unit vector. It is also known as Direction Vector. Learn vectors in detail here. For example, vector v = (1,3) is not a unit vector, because its magnitude is not equal to 1, i.e., |v| = √ (1 2 +3 2 ) ≠ 1.

X3 i=1 A iB i = X3 i=1 X3 j=1 A ijδ ij. Note that there are nine terms in the final sums, but only three of them are non-zero. • The ith component of the cross produce of two vectors A×B becomes (A×B) i = X3 j=1 X3 k=1 ε ijkA jB k. Again, there are nine terms in the sum, but this time only two of them are non-zero.l x, which gives us that ∂ ∂xl xT Ax = Xn i=1 xiail + ˜a T lx = a T x+ ˜aT x.

So e − π jn = (e π j) − n = ( − 1) − n. I am assuming j is the imaginary unit, or √− 1. It's best to simply sketch an Argand diagram for this. You will soon see that the value of enπj just oscillates between − 1 and 1 depending on whether n is odd or even hence it is equal to ( − 1)n.
