While embodied agents have made significant progress in performing complex physical tasks, real-world applications demand more than pure task execution. The agents must collaborate with unfamiliar agents and human users, whose goals are often vague and implicit. In such settings, interpreting ambiguous instructions and uncovering underlying desires is essential for effective assistance. Therefore, fast and accurate desire alignment becomes a critical capability for embodied agents. In this work, we first develop a home assistance simulation environment HA-Desire that integrates an LLM-driven proxy human user exhibiting realistic value-driven goal selection and communication. The ego agent must interact with this proxy user to infer and adapt to the user's latent desires. To achieve this, we present a novel framework FAMER for fast desire alignment, which introduces a desire-based mental reasoning mechanism to identify user intent and filter desire-irrelevant actions. We further design a reflection-based communication module that reduces redundant inquiries, and incorporate goal-relevant information extraction with memory persistence to improve information reuse and reduce unnecessary exploration. Extensive experiments demonstrate that our framework significantly enhances both task execution and communication efficiency, enabling embodied agents to quickly adapt to user-specific desires in complex embodied environments.


Ticker: Bejeweled, Centipede among hall of famers; Mortgages at all-time low; 1.5M new unemployment applications

Boston Herald

The World Video Game Hall of Fame inducted Bejeweled, Centipede, King's Quest and Minecraft in a virtual ceremony Thursday that recognized their influence on the industry and the gamers who have spent tens of billions of hours playing them. The hall of fame's Class of 2020 was chosen from a field of 12 finalists that also included Frogger, Goldeneye 007, Guitar Hero, NBA Jam, Nokia Snake, Super Smash Bros. Melee, Uncharted 2, and Where in the World is Carmen Sandiego? Long-term U.S. mortgage rates fell this week as the benchmark 30-year home loan reached a new all-time low. Mortgage buyer Freddie Mac reported Thursday that the average rate on the key 30-year loan declined to 3.13% from 3.21% last week. It was the lowest level since Freddie began tracking average rates in 1971.


A CIO Hall Of Famer's Approach To Machine Learning

Forbes - Tech

Dan Olley was recently named to the prestigious CIO Hall of Fame by CIO Magazine. In many ways, however, Olley has not been a traditional chief information officer. For one, he has largely held chief technology officer roles. Moreover, he has also had customer-facing, product-centric roles. In his current role as Chief Technology Officer and Executive Vice President of Product Development of Elsevier, his purview is quite broad.


The video game hall of famers

The Guardian

The road from Space Invaders to Grand Theft Auto III is a long and winding one, but this week both were inducted into the World Video Game Hall of Fame. They join last year's crop – Pong, Super Mario Bros, Pac-Man, Doom, World of Warcraft and Tetris – along with four other new inductees. The history of those games is also the history of how we play them. Pac-Man, for example, was first released in the arcades in 1980. It went from PCs to Game Boys to consoles.
