Huawei HCIE-AI Practice Questions - Huawei Certified ICT Expert - Artificial Intelligence (Written H13-541+ Lab + Interview) Exam - Huawei HCIE-AI Practice Questions - Huawei Certified ICT Expert - Artificial Intelligence (Written H13-541+ Lab + Interview) Exam

Question 1

For a real symmetric positive-definite matrix A, which statement about its eigendecomposition A = QΛQᵀ is TRUE?

Q is unitary and Λ contains complex eigenvalues Q is orthogonal and Λ contains strictly positive eigenvalues Q must be lower triangular and Λ has real entries Q is the identity matrix and Λ equals A

Correct Answer:

Q is orthogonal and Λ contains strictly positive eigenvalues

Question 2

In the SVD of a real m×n matrix A = UΣVᵀ, what do the columns of V represent geometrically?

The left singular vectors that diagonalize AAᵀ The right singular vectors that diagonalize AᵀA The eigenvectors of A itself The principal components scaled by the singular values

Correct Answer:

The right singular vectors that diagonalize AᵀA

Question 3

Cross-entropy loss between a one-hot target y and softmax prediction p is H(y, p) = -Σ y_i log p_i. How does this relate to KL divergence?

Cross-entropy and KL divergence are unrelated quantities H(y, p) = KL(p || y) and is symmetric H(y, p) is mutual information between y and p H(y, p) = KL(y || p) + H(y), and since H(y) is constant for fixed y, minimizing cross-entropy equals minimizing KL(y || p)

Correct Answer:

H(y, p) = KL(y || p) + H(y), and since H(y) is constant for fixed y, minimizing cross-entropy equals minimizing KL(y || p)

Question 4

In Bayesian inference, MLE and MAP differ in that:

MAP adds a log-prior term to the log-likelihood; MLE uses only the log-likelihood MAP averages over all parameter values while MLE picks one MLE is Bayesian and MAP is frequentist MAP and MLE always give identical answers under any prior

Correct Answer:

MAP adds a log-prior term to the log-likelihood; MLE uses only the log-likelihood

Question 5

The mutual information I(X; Y) between two random variables can be written as:

H(X, Y) - H(X) - H(Y) H(X) - H(Y) H(X) + H(Y) - H(X, Y) KL(X || Y)

Correct Answer:

H(X) + H(Y) - H(X, Y)
