Learning from Demonstrations (LfD) and Reinforcement Learning (RL) have enabled robot agents to accomplish complex tasks. Reward Machines (RMs) enhance RL's capability to train policies over extended time horizons by structuring high-level task information. In this work, we introduce a novel LfD approach for learning RMs directly from visual demonstrations of robotic manipulation tasks. Unlike previous methods, our approach requires no predefined propositions or prior knowledge of the underlying sparse reward signals. Instead, it jointly learns the RM structure and identifies key high-level events that drive transitions between RM states. We validate our method on vision-based manipulation tasks, showing that the inferred RM accurately captures task structure and enables an RL agent to effectively learn an optimal policy.

National Women's Soccer League teams are now represented in the newest version of the FIFA video game, but some players aren't happy with just being included. Several players' portrayals in the video game are off, including Sydney Leroux's. Leroux, a forward for Angel City FC in Los Angeles, tweeted a photo of one of the female characters, who is bald in the game.

Chiquita Evans became the first woman ever drafted into the video game NBA 2K League when she was selected in the fourth round Tuesday night by Warriors Gaming, which is run by the Golden State Warriors. Evans is now the esports league's first female pro. Each of the 126 players in the league will make between $33,000 and $37,000 per season, plus benefits and team housing. "It feels surreal,'' she said. Evans, who lives in Mobile, Ala., was one of two women who qualified for the draft this year through the league's online combine. The other, Brianna Novin, was not selected. The NBA and game publisher Take-Two Interactive run the league. The league had no women in its first season, and the NBA wanted to change that. They hired some analysts to talk to focus groups to determine why only men qualified for the league. "It made us put more emphasis on how good a player was when they got the ball in their hands,'' 2K League managing director Brendan Donohue said.

After a while, we just created a layout of the scene and took it from there." It's a simple story to follow, and most of the action takes place right in front of you. The viewer is free, however, to look elsewhere, and if you're using the Spotlight Stories app, the movie will adapt accordingly. If you look at the musicians, for instance, the main action -- Méliès and his wife -- will wait off-screen until you turn your head back. That's possible because of some special Google software called the Spotlight Stories Editor, which allows for nodal-based logic, similar to what's used in a video game. "It's immersive theater much more than it is a film." Mark Davies, a CG supervisor at Nexus Studios, says it works like punch-drunk-style theater. "It's immersive theater much more than it is a film," he said. "Because the actor is there, and if they see that you're staring at the floor, the ceiling or something else, they'll wait for you to turn around, and go, 'Oh, yes, I can begin acting again.'"

TORONTO/OTTAWA – Officials say a Porter Airlines flight approaching Toronto's island airport took evasive action to avoid a suspected drone, injuring two flight attendants. Julie Leroux of Canada's Transportation Safety Board said the near collision occurred at 7:30 a.m. Leroux says the object involved in the near-miss was likely an unmanned aerial vehicle. Porter spokesman Brad Cicero says two flight attendants sustained minor injuries. They were taken to a hospital and released.
