Abstract--Recent work has demonstrated the utility of Random Forest (RF) proximities for various supervised machine learning tasks, including outlier detection, missing data imputation, and visualization. However, the utility of the RF proximities depends upon the success of the RF model, which itself is not the ideal model in all contexts. RF proximities have recently been extended to time series by means of the distance-based Proximity Forest (PF) model, among others, affording time series analysis with the benefits of RF proximities. In this work, we introduce the generalized PF model, thereby extending RF proximities to all contexts in which supervised distance-based machine learning can occur . Additionally, we introduce a variant of the PF model for regression tasks. We also introduce the notion of using the generalized PF model as a meta-learning framework, extending supervised imputation capability to any pre-trained classifier . We experimentally demonstrate the unique advantages of the generalized PF model compared with both the RF model and the k-nearest neighbors model.

Researchers from the University of Cambridge compared brain scans of 3,802 people aged between 0 and 90. Their analysis revealed that the average human life is split up by four pivotal'turning points' between five key stages - childhood, adolescence, adulthood, early ageing, and late ageing.

The brain goes through five distinct phases in life, with key turning points at ages nine, 32, 66 and 83, scientists have revealed. Around 4,000 people up to the age of 90 had scans to reveal the connections between their brain cells. Researchers at the University of Cambridge showed that the brain stays in the adolescent phase until our early thirties when we peak. They say the results could help us understand why the risk of mental health disorders and dementia varies through life. The brain is constantly changing in response to new knowledge and experience - but the research shows this is not one smooth pattern from birth to death.

Talks in Geneva between the US and Ukraine aimed at ending the war with Russia have concluded, with officials from both sides reporting progress and an intention to continue working. However, no details have emerged on how to bridge the considerable divide between Moscow and Kyiv over territorial issues and security guarantees for Ukraine. Ukraine's president Volodymyr Zelensky welcomed the important steps that had been made but warned that the main problem facing the peace talks was Vladimir Putin's demand for legal recognition of Russian-occupied territories in eastern Ukraine. This would break the principle of territorial integrity and sovereignty, he said, highlighting concerns that Moscow could be rewarded for its aggression with land it seized by force. Meanwhile, President Donald Trump suggested on social media that something good just may be happening, but with the caveat: Don't believe it until you see it.

'No one will support it': Ukraine's soldiers react to US peace plan Ukraine's frontline soldiers have reacted to draft US peace proposals with a mixture of defiance, anger and resignation. The BBC spoke to half a dozen who sent us their views via social media and email in response to the original US plan - details of which were leaked last week. Since then, American and Ukrainian negotiators have been working on changes to the proposals - and are set to continue talks about the peace framework. Of the original US plan, Yaroslav, in eastern Ukraine, says it sucks no one will support it while an army medic with the call sign Shtutser dismissed it as an absolutely disgraceful draft of a peace plan, unworthy of our attention. But one soldier with the call sign Snake told us it's time to agree at least on something.

Rubio hails'tremendous progress' at Ukraine peace talks A tremendous amount of progress has been achieved in talks to finalise a US-proposed peace plan to end the Russia-Ukraine war, Secretary of State Marco Rubio has said. But there's still some work to be done, Rubio said after meeting Ukrainian and European negotiators in Geneva, Switzerland. Ukrainian President Volodymyr Zelensky said there were signals that President [Donald] Trump's team is hearing us. Ukraine and its European allies had expressed concern over the leaked proposals, seen as favouring Russia and welcomed by Vladimir Putin as the basis for settlement. Zelensky had said Ukraine might face a very difficult choice: either losing dignity, or risk losing a key partner.

How can you tell if your new favourite artist is a real person? There's a new song doing the rounds, and in the immortal words of Kylie Minogue, you just can't get it out of your head. But what if it was created by a robot, or the artist themself is a product of artificial intelligence (AI)? Do streaming sites have an obligation to label music as AI-generated? And does it even matter, if you like what you hear?

Senior Pentagon officials have arrived in Ukraine to discuss efforts to end the war with Russia, the US military has said. The team, led by US Army Secretary Dan Driscoll, is expected to meet Ukrainian President Volodymyr Zelensky in Kyiv on Thursday when he returns from a trip to Turkey. Reports began surfacing on Wednesday that the US and Russia had prepared a new peace plan, containing major concessions from Ukraine. Neither Washington nor Moscow has officially confirmed the plan. Earlier in the day, at least 26 people were killed in a Russian missile and drone attack on Ukraine's western city of Ternopil, officials there said.

Why quasicrystals shouldn't exist but are turning up in strange places Matter with "forbidden" symmetries was once thought to be confined to lab experiments, but is now being found in some of the world's most extreme environments In autumn 1945, Lincoln LaPaz crouched over a patch of scorched ground in the Jornada del Muerto desert of New Mexico. LaPaz, an astronomer, was out hunting for meteorites. He had spotted something in the dust: a strange, glittering crust of blood-red glass. This was no meteorite, but it was striking enough that he held onto it. It wasn't until decades later that anyone would realise quite how special LaPaz's chance find was.
