COMS 4701 Artificial Intelligence
Facial Recognition remains one of the most popular fields in computer imaging research due to its broad scope of applications in identity verification, human computer interactions, law enforcement applications and video surveillance systems. Although numerous artificial intelligence and machine learning techniques have been successfully applied to still image recognitions, recognition in video ...
متن کاملCOMS 4721: Review of prerequisites
The d-dimensional Euclidean space Rd is the d-dimensional vector space over the real numbers R where we have the familiar notions of distances and angles from classical plane geometry. The space Rd is comprised of vectors (or points), which can be added (z := x + y for x,y ∈ Rd) and scaled by real numbers (z := cx for c ∈ R and x ∈ Rd) to obtain other vectors in Rd. Every vector x ∈ Rd has a (E...

f(x) = { 1 if wx+ b > 0, −1 otherwise. Consider d+1 points x = (0, ..., 0) , x = (1, 0, ..., 0) , x = (0, 1, ..., 0) , ..., x = (0, 0, ..., 1) . After these d+1 points being arbitrarily labeled: y = (y0, y1, ..., yd) T ∈ {−1, 1}. Let b = 0.5 · y0 and w = (w1, w2, ...wd) where wi = yi, i ∈ {1, 2, ..., d}. Thus f(x) can label all these d+ 1 points correctly. So the VC dimension of perceptron is a...

Consider a scenario where you have to repeatedly make a decision on some important matter, and each decision has some quantifiable consequence which you would like to optimize. Formally, suppose there are T rounds of this decision-making game. In each round, you (the “learner”) must choose between two actions, {−1,+1}. Your adversary (Nature) picks one of the actions for that round to be correc...
