Questions & Answers

Q: How does machine learning differ from theoretical computer science?

Machine learning is more empirical in nature, relying on observation of algorithmic performance for practical applications. Theoretical computer science, on the other hand, focuses on abstract concepts and proofs.

Q: What are some fields that have seen success in machine learning?

Machine learning has been successful in image processing, robotics, natural language processing, and game playing. It has revolutionized these fields and led to significant advancements.

Q: What are the limitations of machine learning?

One limitation is the lack of theoretical understanding behind why machine learning algorithms perform well on inputs outside the training set. Additionally, the solutions generated by machine learning networks are often difficult to understand and interpret.

Q: Can machine learning algorithms develop algorithms to solve problems?

Machine learning algorithms are algorithms themselves, but they do not have the same algorithmic style manipulation of inputs seen in traditional computer science algorithms. They function more like computable functions that provide outputs based on given inputs.

Summary & Key Takeaways

• Machine learning differs from theoretical computer science, focusing on empirical performance and algorithmic evaluation.

• It has seen significant successes in image processing, robotics, and game playing.

• However, limitations include a lack of theoretical understanding and difficulty in interpreting the solutions and features derived from machine learning algorithms.
