HAPI Explorer: Comprehension, Discovery, and Explanation on History of ML APIs

Machine learning prediction APIs offered by Google, Microsoft, Amazon, and many other providers have been continuously adopted in a plethora of applications, such as visual object detection, natural language comprehension, speech recognition. Despite the importance systematic study comparison different over time, this topic is currently under-explored because lack data user-friendly exploration tools. To address issue, we present HAPI Explorer (History API Explorer), an interactive system that offers easy access to millions instances commercial applications collected three years, prioritize attention on user-defined instance regimes, explain interesting patterns across APIs, subpopulations, time periods via languages. can facilitate further comprehension exploitation ML APIs.
