Accuracy vs precision vs. recall in machine learning: what’s the difference? In many cases, you can use words like “sell” and “fell” and Siri can tell the difference, thanks to her speech recognition machine learning. Speech recognition also plays a role in the development of natural language processing (NLP) models, which help computers interact with humans. In unsupervised learning, the algorithms cluster and analyze datasets without labels. They then use this clustering to discover patterns …
