Apple today is trading $318.25, it is trading higher with $0.14 mainly because it has acquired Inductive, A machine-learning (ML) start-up that uses artificial intelligence (AI) to automatically identify and correct errors that may be lurking in data. This marks the second such acquisition in as many months aimed at improving the functionality of Siri, the iPhones voice-activated digital assistant. The company confirmed the deal using its typical boilerplate language, saying that Apple "buys smaller technology companies from time to time, and we generally do not discuss our purpose or plans. "ML is a branch of AI that helps computers learn tasks without being specifically programmed for them. The systems use sophisticated algorithms to sift through reams of data, finding patterns that might otherwise be missed, and drawing conclusions based on what it finds. The system can then independently improve, making more accurate predictions based on what it has learned. Having clean data to work with is a key component of a successful ML system and these tools may result in incremental improvements to Siri.
