 AVL trees guarantee O(log n) search time, not O(n).

Graphs and trees are non-linear data structures, while linked-list, queue, and stack are linear.

Graphs and trees are non-linear data structures, while linked-list, queue, and stack are linear.

Insertion sort runs in O(n) time when the array is already sorted (best case).

VC dimension stands for Vapnik–Chervonenkis dimension, a measure of model capacity/complexity.

Artificial Neural Networks (ANNs) are computational algorithms inspired by biological neural networks.

One-class SVM is mainly used for anomaly/outlier detection, which falls under unsupervised learning.
