Explainable AI: How and why did the AI say 'true'?

Artificial intelligence (AI) is expanding beyond academics and the web giants, who have immense access to data and computing power and deep pockets to fund research projects. There is a lot of hype, but companies are being urged to embrace AI. Two studies published recently have emphasised the importance of businesses adopting AI to remain competitive. The Let's get real about AI study from OC&C consultants reported that spending on AI has been huge: $219bn was spent by businesses on AI globally in 2018, equivalent to about 7% of the total enterprise IT spend. AI spend in the US was $91bn in 2018, and $12bn in the UK.
