Gaussian Mixture Model: Examples, Advantages and Disadvantages - Shiksha Online

SOLVED:Spreading of a Gaussian wave packet. The Gaussian wave packet Ψ(x, 0) of Example 6.3 is built out of plane waves according to the amplitude distribution function a(k)=(C α/ √(π)) (-α^2 k^2) . Calculate Ψ(x, t) for this packet and describe its evolution.

SOLVED:The gaussian wave packet. A free particle has the initial wave function Ψ(x, 0)=A e^-a x^2 where A and a are constants ( a is real and positive). (a) Normalize Ψ(x, 0). (b) Find Ψ(x, t) . Hint: Integrals of the form ∫-∞^ ∞ e^-(a x^2 b x) d x can be handled by "completing the square": Let y ≡√(a)[x (b / 2 a)], and note that (a x^2 b x)=y^2-(b^2 / 4 a). Answer: Ψ(x, t)=((2 a)/(π))^1 / 4 (e^-a x^2 / 11 (2 i ħa t / m))/(√(1 (2 i ħa t / m))) (c) Find |Ψ(x, t)|^2. Express your answer in terms o

SOLVED: The Gaussian wave packet. A free particle has the initial wave function ψ(x,0) = Ae^(-ax^2), where A and a are (real and positive) constants.(a) Normalize ψ(x,0).(b) Find Δx(Δp).(c) Find |ψ(x,t)|^2.(d) Find ⟨x⟩, ⟨p⟩, ⟨x^2⟩, ⟨p^2⟩.

Gaussian Mixture Model Clustering Vs K-Means: Which One To Choose

SOLVED: (Gaussian Mixture Model (GMM)) This question is about a simplified version of the Gaussian Mixture Model (GMM), which is a popular model in statistics, data science, and machine learning. For example, it is used in image processing and various clustering algorithms. Suppose that K is a discrete random variable that can take either 0 or 1 with probabilities P(K=0) and P(K=1) respectively, that is, with probability P(K=0) and with probability P(K=1) = 4 - P(K=0).Conditional on K=k with k â
