Sir Mark said the force had designed an extensive and complex policing operation to keep carnival-goers, expected to be more than one million in number, safe.
He wrote: “We acknowledge that when LFR was previously deployed at Notting Hill Carnival in 2016 and 2017, it did not build public confidence.
“At that time, the technology was in its early stages and the algorithm’s performance was limited. The legal and oversight position was also very different.”
He said that since, the technology had made “considerable progress”, and had an improved algorithm that performed at a higher standard.
“We have also refined our operational approach – including not using LFR within the Carnival footprint,” he added.
“These developments reflect our commitment to learning from experience and improving how we support public safety while maintaining trust.”
