What is Dijkstra's algorithm and how is it used in machine learning?

Dijkstra's algorithm is a graph search algorithm that finds the shortest path between nodes. In machine learning, it's often used in optimization problems, such as finding the most efficient route in a neural network.

Can you give me an example of how it's applied in a real-world scenario?

Sure! One real-world application is in routing algorithms for GPS systems, where Dijkstra's algorithm helps determine the shortest path from one location to another.

Are there any limitations to using Dijkstra's algorithm?

Yes, Dijkstra's algorithm can be inefficient for very large graphs, as its time complexity is O(V^2) in the worst case. It also requires non-negative weights.

What are some alternatives to Dijkstra's algorithm?

Alternatives include A* search algorithm, Bellman-Ford algorithm, and Floyd-Warshall algorithm, each with its own advantages depending on the use case.
