Questions & Answers

Q: Why does machine learning progress become harder as it approaches human level performance?

Machine learning progress becomes harder as it approaches human level performance because the distinction between avoidable bias and variance becomes less clear, making it challenging to know how to improve the algorithm.

Q: Is it possible for machine learning to surpass human level performance in certain tasks?

Yes, in tasks such as online advertising, product recommendations, logistics, and loan approval, machine learning algorithms have shown to achieve better performance than humans due to their ability to learn from structured data and access vast amounts of information.

Q: What types of problems are humans generally better at than computers in machine learning?

Humans tend to outperform computers in natural perception tasks such as computer vision, speech recognition, and natural language processing. These tasks require a level of understanding and interpretation that is more challenging for machines to replicate.

Q: What are some examples of tasks in which computers have surpassed human level performance?

Computers have achieved human-level performance in tasks such as speech recognition and certain image recognition tasks. Additionally, in medical fields like reading ECGs, diagnosing skin cancer, and some radiology tasks, computers are showing promising results.

Summary & Key Takeaways

• Surpassing human level performance in machine learning proves to be more difficult as algorithms approach or surpass human accuracy.

• Estimating avoidable bias is easier when there is a clear difference in error rates between human performance and algorithm performance.

• When algorithm performance approaches human performance, determining avoidable bias becomes more challenging.
