Decision-Calibrated Conformal Uncertainty for Pacing Decisions in Streaming Advertising
Shekhar, Prashant, Howard, Caroline
We develop a decision-calibrated conformal framework for pacing decisions in streaming advertising. Pacing depends on uncertain future inventory, demand pressure, incremental response, and member-experience load. Instead of calibrating a generic forecast residual, the framework measures forecast error by its largest impact on the policies that could actually be deployed. The main theorem shows that the proposed score is the smallest valid uncertainty measure that uniformly protects all deployable pacing policies. Geometrically, it is the support function of the signed policy sensitivity set. Split conformal calibration gives finite-sample coverage for this score. A high-dimensional separation theorem shows that traditional residual calibration can be arbitrarily more conservative by paying for nuisance inventory dimensions, and a robust pacing result combines inventory, response, and experience uncertainty. On public-data-calibrated pacing replays built from Criteo Uplift and KuaiRand datasets, traditional conformal pacing remains unresolved with high residual radii of 7236.7 on Criteo and 4629.4 on KuaiRand. With the proposed decision calibration approach, the uncertainty radii are reduced to 18.4 and 278.6 respectively, with separate margins for value, delivery, budget, and member load. On Criteo, the proposed method certifies a less aggressive pacing policy than the point-forecast baseline, and reduces held-out any-violation rate from 16.7% to 3.3%, with zero budget and member-load violations. On KuaiRand, the choice remains unresolved. In a nutshell, the paper establishes that forecasts, response estimates, and member-experience models should be judged by whether they shrink the uncertainty that the pacing decision uses, as this leads to confident decisions that are not overly conservative.
Robot Talk Episode 158 – Autonomous robot deliveries, with Ahti Heinla
Claire chatted to Ahti Heinla from Starship Technologies about their AI-powered delivery robots that operate independently on streets and pavements. Ahti Heinla is the co-founder and CEO of Starship Technologies, the world's leading autonomous delivery company building AI-powered robots that operate fully independently in real-world environments. One of the original engineers behind Skype's billion-dollar success, Ahti later made a quiet pivot into robotics, spending the past decade advancing practical, consumer-facing AI. Under his leadership, Starship has completed more than 10 million autonomous deliveries with a fleet of over 2,700 robots navigating streets, pavements, weather, and people, without human intervention. Robot Talk is a weekly podcast that explores the exciting world of robotics, artificial intelligence and autonomous machines.
Amazon rolls out its new 30-minute delivery option in a number of cities across the US
Amazon is rolling out its ultra-fast delivery service, Amazon Now, in dozens of cities in the US, promising deliveries of groceries and household essentials in 30 minutes or less. Amazon says the service is also now widely available in Atlanta and Dallas-Fort Worth, and will rapidly expand into Austin, Houston, Minneapolis, Orlando, Phoenix, Denver, Oklahoma City and more throughout the rest of 2026. If Amazon Now is available in your area you'll see a 30-Minute Delivery option in the Amazon app or on the homepage when you're in a browser. Amazon Now offers will also be highlighted when you're browsing products. You can search by category, and as well as groceries and basic household items such as eggs, diary and laundry detergent, you can also order select electronics on the service, which Amazon says operates 24 hours a day in most places.
Papa Johns Is Getting Into Drone Delivery--but Not for Pizza
A new collaboration with Alphabet's Wing will only deliver sandwiches. It demonstrates the tricky parts of taking to the sky. Starting today, eager customers of the US pizza restaurant chain Papa Johns living in one corner of southern North Carolina will have the opportunity to receive their food from the sky, thanks to a new collaboration with Alphabet's drone company, Wing . But Papa Johns' signature pizzas won't be on offer. Instead, drone-loving North Carolinians will have to choose between three kinds of sandwiches, a newer product for the fast-food chain: Philly cheesesteak, chicken bacon ranch, or steak and mushroom varieties.
'We had people come just to see it': Amazon delivers its first UK parcels by drone
'We had people come just to see it': Amazon delivers its first UK parcels by drone Amazon has become the first retailer in the UK to start a drone delivery service with a limited launch in Darlington, County Durham. Packages weighing less than 5lb (2.2kg) and containing everyday items such as beauty products, batteries and cables are now being delivered within a 7.5 mile (12km) radius of Amazon's fulfilment centre. The tech giant is convinced there is demand for ultra-fast deliveries and hopes to slowly expand the service. Rob Shield let Amazon use an Airbnb on his farm for its first test runs. Initially it was a novelty, so we were ordering everything under the sun, he says.
NHS deal with AI firm Palantir called into question after officials' concerns revealed

The June 2025 briefing to Wes Streeting (2nd left) was released under the Freedom of Information Act. NHS deal with AI firm Palantir called into question after officials' concerns revealed Health officials fear Palantir's reputation will hinder the delivery of a "vital" £330m NHS contract, according to briefings seen by the Guardian, sparking fresh calls for the deal to be scrapped. In 2023, ministers selected Palantir, a US surveillance technology company that also works for the Israeli military and Donald Trump's ICE operation, to build an AI-enabled data platform to connect disparate health information across the NHS . Now it has emerged that after Keir Starmer demanded faster deployment, Whitehall officials privately warned that the public perception of Palantir would limit its rollout, meaning the contract would not offer value for money.
Wing's drone deliveries are coming to 150 more Walmarts
Wing's drone deliveries are coming to 150 more Walmarts The service expansion will reach Walmart customers in Los Angeles, St. Louis, Cincinnati, Miami and other US metro areas. Don't be surprised if you see even more drones delivering groceries across the US since the Alphabet-owned Wing announced another service expansion with Walmart over the next year. The partnership said that drone delivery services will be available at 150 more Walmart locations in Los Angeles, St. Louis, Cincinnati, Miami and more metros that have yet to be announced. According to Wing, its top 25 percent of customers have ordered its delivery drones up to three times a week. To meet growing demand, Wing and Walmart said it will serve up to 40 million US customers and build up a network of 270 delivery locations by 2027.
