Machine learning (ML) is defined as the scientific study of algorithms and statistical models that computer systems use to perform a specific task without using explicit instructions. Instead, the system relies on using patterns and inference instead. Machine learning can often achieve in days or hours what might take humans years to program. They may be able to find patterns within data that a human analyst could not discern.
Many industries continue to develop machine learning applications. The technology and communications industry has the highest adoption rate (32%) for Artificial Intelligence (AI) with a focus on machine learning. The Department for Transport (DfT) have launched several ML-powered projects in 2019. These include the Traffic Signal Advisor Service (TSAS) to optimise traffic control and reduce congestion, and prediction of post-accident road network recovery time.
