, Q1. In the context of support vector machines (SVMs) with a radial basis function (RBF) kernel, which of the
following best describes the effect of increasing the kernel parameter gamma () to a very large value?
A. The decision boundary becomes highly non-linear and may overfit the training data, potentially capturing
noise as support vectors.
B. The decision boundary becomes approximately linear, reducing the model's capacity and increasing bias.
C. The model becomes equivalent to a linear SVM because the RBF kernel approximates a linear kernel as ->.
D. The training time increases quadratically with the number of samples due to the kernel matrix becoming
dense.
Correct Answer: A. The decision boundary becomes highly non-linear and may overfit the training data,
potentially capturing noise as support vectors.
Rationale: A large gamma in RBF kernel means each training example has a narrow influence region, making the
decision boundary highly flexible and prone to overfitting (capturing noise). Option B is incorrect because large
gamma leads to complex, not linear, boundaries. Option C is false: RBF kernel does not become linear; it becomes
extremely localized. Option D is a practical issue but not the primary statistical effect of gamma on the decision
boundary.
Why Wrong:
B - Large gamma increases model complexity, not linearity; it reduces bias but increases variance.
C - As ->, the RBF kernel does not approach a linear kernel; it becomes a delta-like function, causing extreme
overfitting.
D - Training time may increase, but this is a computational effect, not the primary impact on the decision
boundary shape.

Q2. A data scientist applies principal component analysis (PCA) to a dataset with 100 features and retains
the first 10 principal components that explain 95% of the variance. Which of the following interpretations is
most accurate?
A. The original features are linearly independent because PCA requires uncorrelated inputs.
B. The 10 principal components are a subset of the original 100 features, selected based on variance
contribution.
C. Each principal component is a linear combination of all 100 original features, and the reduced representation
captures most of the total variance.
D. The 10 principal components are orthogonal to each other but may still have non-zero correlation with the
original features.
Correct Answer: C. Each principal component is a linear combination of all 100 original features, and the
reduced representation captures most of the total variance.
Rationale: PCA constructs principal components as linear combinations of all original features, not as a subset.
The first 10 components capture 95% of total variance, meaning the reduced representation preserves most
information. Option A is false: PCA does not require linear independence of original features; it works on
covariance structure. Option B confuses feature selection with feature extraction. Option D is partially true about
orthogonality but misses the key point that components are linear combinations of all features.
Why Wrong:
A - PCA can be applied to correlated features; it does not assume linear independence.
B - PCA is a feature extraction method, not feature selection; components are combinations of all features.
D - While components are orthogonal, the statement omits the crucial fact that they are linear combinations of
all original features.
