Survival analysis is a fundamental tool for modeling time-to-event outcomes in healthcare. Recent advances have introduced flexible neural network approaches for improved predictive performance. However, most of these models do not provide interpretable insights into the association between exposures and the modeled outcomes, a critical requirement for decision-making in clinical practice. To address this limitation, we propose Additive Deep Hazard Analysis Mixtures (ADHAM), an interpretable additive survival model. ADHAM assumes a conditional latent structure that defines subgroups, each characterized by a combination of covariate-specific hazard functions. To select the number of subgroups, we introduce a post-training refinement that reduces the number of equivalent latent subgroups by merging similar groups. We perform comprehensive studies to demonstrate ADHAM's interpretability at the population, subgroup, and individual levels. Extensive experiments on real-world datasets show that ADHAM provides novel insights into the association between exposures and outcomes. Further, ADHAM remains on par with existing state-of-the-art survival baselines in terms of predictive performance, offering a scalable and interpretable approach to time-to-event prediction in healthcare.

In a normal year, Blizzard's annual fan convention would have involved tens of thousands of cosplayers, esports pros, players and developers meeting and mingling in Anaheim, California. But, thanks to Covid, the video game developer was forced to postpone 2020's convention and instead celebrate its 30th year with a virtual convention last weekend. Given this significant anniversary, it makes sense that many of the announcements were targeted at nostalgic fans. Three of Blizzard's older titles (Lost Vikings, Rock & Roll Racing and Blackthorne) have been bundled together in the Blizzard Arcade Collection. World of Warcraft Classic, which takes players back to the venerable MMO's earliest days, will get a recreation of its first expansion, Burning Crusade.

Mike Morhaime has been a part of Blizzard since it was founded in 1991 as Silicon & Synapse, Inc., and now he's stepping down from his role as president and CEO. Former executive producer and senior VP for World of Warcraft J. Allen Brack will take over as president, while Ray Gresko (Overwatch, Diablo III) will step in as chief development officer, while co-founder and former WoW lead designer Allen Adham will join the executive leadership team. In a statement, Morhaime said "After many years of working with some of the industry's most talented people to create games and worlds for you to play in, I've decided it's time for someone else to lead Blizzard Entertainment. I will now serve as an advisor to the company I so love and admire...I truly believe that this amazing community has the potential to be a shining light to the rest of the industry by setting a positive example of inclusivity, tolerance, and acceptance toward others. In the words of one of Blizzard's core values: remember to always play nice; play fair. Mike – thank you for everything: for setting the foundation for the games, worlds and communities that we love, and for being a guiding light and an example for us all. To our community, please read here for messages from Mike Morhaime and J. Allen Brack. Morhaime has overseen incredible growth, as Blizzard has created franchises that dominate online gaming with WoW, Diablo, Starcraft, Overwatch and Hearthstone. Now as the company continues to grow and invest in new areas like eSports, it also has other new projects in development. GamesIndustry.biz notes that Adham left in 2004 before returning in 2016 after it had grown from around 400 employees to more than 4,000 as executive producer of incubation, and according to Brack, he will continue to oversee development of "several" new games. Brack said in his own letter to expect a few surprises at Blizzcon in a month and that "Joining the World of Warcraft team and my favorite game company nearly 13 years ago was an unimaginable dream.
