Private Learner Cuts Mistake Bound for Littlestone Classes

A new private learner reduces the mistake bound for Littlestone classes to ~O(d^9.5·log T) and the private PAC sample complexity to ~O(d^5·log(1/δβ)/(εα)), closing the gap to known lower bounds. getnews.me/private-learner-cuts-mis... #privacy #littlestone

@drgarywalker.bsky.social Brief video looking north towards #Littlestone from #Greatstone beach this lunchtime showing the dancing sand 😊 #video #ukweather #stormhour #kent

Lone kite surfer today, not certain if they're brave or mad in the stiff and cold NE wind.

Wonderful reflections at Littlestone

This beach groyne is probably only one storm away from becoming driftwood on the beach

Phoenix Caisson in the background stranded in the silt in 1944 at Littlestone where it has remained ever since as a reminder of D-day.

Fed up with the cold, overcast weather but also fed up with being indoors, so took a lunchtime walk along the beach to #Littlestone. Cold in the nagging NE wind off the sea but nice to be out in the fresh air. Very little colour in any of the photos today #photography #ukweather #stormhour #kent

More from #Greatstone and #Littlestone beaches this afternoon, wonderful light, clouds and reflections #photography #ukweather #stormhour #coast #sea #kent

Just a beautiful day for a walk along the beach. This photo was taken looking south this afternoon from #Littlestone with the beach to the left and the puddles on the unmade road to the right. Stunning reflections of the mackerel sky 😊 #photography #ukweather #stormhour #coast #kent

"Leading the fight to clean up our seas"

Read my article in the Folkestone Herald last week where I describe ongoing efforts to tackle water pollution along the District's beautiful coastline.

1/3

It’s encouraging that St Mary’s Bay bathing water has moved from ‘poor’ to ‘sufficient’.

But it’s obviously incredibly frustrating that #Dymchurch has been downgraded to ‘poor’, as is #Littlestone, with ‘no swim’ warnings now in place at both beaches.
