Machine Learning Interview Questions

"To get a job in machine learning, you must have the programming and mathematical knowledge to create artificial intelligence that is capable of learning new tasks without being explicitly coded. In an interview you may be asked about your experience with pertinent coding languages such as Java and C++ as well as with writing algorithms. The interview will be comprised mainly of technical questions that test your knowledge of the fundamental concepts of machine learning such as data mining and signal processing."

You are given a very large symmetric matrix 𝐴 A that doesn’t fit into memory, 𝐴 ∈ 𝑅 1 𝑀 × 1 𝑀 A∈R 1M×1M , and a function 𝑓 ( 𝑥 ) = 𝐴 𝑥 f(x)=Ax that can quickly compute 𝑓 ( 𝑥 ) f(x) for 𝑥 ∈ 𝑅 1 𝑀 x∈R 1M . How would you find the unit vector 𝑥 x that minimizes 𝑥 𝑇 𝐴 𝑥 x T Ax?
