i think the use of hlp and machine learning had taken off partly because it helped people get papers published to show they can beat hlp there's also been a bit misused in settings where the goal is to build a valuable application not just to publish a paper when the ground truth is externally defined then there are fewer problems with hlp when the...

Questions & Answers

Q: Why has HLP gained popularity, and how has it been misused?

HLP has gained traction as it helps demonstrate the superiority of machine learning models over human performance, especially in research papers. However, it may be misused when the goal is to build an actual valuable application instead of just proving superiority over human performance.

Q: In what scenarios does HLP provide valuable insights?

HLP is particularly useful when the ground truth is defined by an external measure, like a medical biopsy, as it allows for measuring the accuracy of both doctors and machine learning algorithms. This can aid in predicting outcomes in medical imaging or similar applications.

Q: How can HLP be improved in cases with inconsistent labeling instructions?

Inconsistent labeling instructions can result in lower HLP. By working towards improving labeling consistency, both HLP and data quality can be enhanced, leading to improved performance of machine learning algorithms.

Q: Is HLP relevant for structured data problems?

Yes, HLP can be useful in structured data problems that involve human labeling, such as merging user IDs or classifying fraudulent transactions. In these cases, improving labeling consistency can improve both HLP and machine learning algorithm performance.

Summary & Key Takeaways

  • HLP is crucial for applications where human performance serves as a benchmark, such as medical imaging diagnosis or visual inspection.

  • Inconsistencies in labeling instructions can lead to lower HLP, but improving labeling consistency can enhance both HLP and machine learning algorithm performance.

  • HLP is relevant not only for unstructured data but also for structured data problems that require human labeling.
