cat fishing meaning Doctored images have been around for decades. The term "Photoshopped" is part of everyday language. But in recent years, it has seemingly been replaced by a new word: deepfake. It's almost everywhere online, but you likely won't find it in your dictionary at home. What exactly is a deepfake, and how does the technology work? RELATED STORY | Scripps News Reports: Sex, Lies, and Deepfakes A deepfake is an image or video that has been generated by artificial intelligence to look real. Most deepfakes use a type of AI called a "diffusion model." In a nutshell, a diffusion model creates content by stripping away noise. "With diffusion models, they found a very clever way of taking an image and then constructing that procedure to go from here to there," said Lucas Hansen said. He and Siddharth Hiregowdara are cofounders of CivAI, a nonprofit educating the public on the potential — and dangers — of AI. How diffusion models work It can get complicated, so imagine the AI – or diffusion model – as a detective trying to catch a suspect. Like a detective, it relies on its experience and training. It recalls a previous case -– a sneaky cat on the run. Every day it added more and more disguises. On Monday, no disguise. Tuesday, it put on a little wig. Wednesday, it added some jewelry. By Sunday, it's unrecognizable and wearing a cheeseburger mask. The detective learned these changes can tell you what it wore and on what day. AI diffusion models do something similar with noise, learning what something looks like at each step. "The job of the diffusion model is to remove noise," Hiregowdara said. "You would give the model this picture, and then it will give you a slightly de-noised version of this picture." RELATED STORY | Scripps News got deepfaked to see how AI could impact elections When it's time to solve the case and generate a suspect, we give it a clue: the prompts we give when we create an AI-generated image. "We have been given the hint that this is supposed to look like a cat. So what catlike things can we see in here? Okay, we see this curve, maybe that's an ear," Hiregowdara said. The "detective" works backward, recalling its training. It sees a noisy image. Thanks to the clue, it is looking for a suspect — a cat. It subtracts disguises (noise) until it finds the new suspect. Case closed. Now imagine the "detective" living and solving crimes for years and years. It learns and studies everything — landscapes, objects, animals, people, anything at all. So when it needs to generate a suspect or an image, it remembers its training and creates an image. Deepfakes and faceswaps Many deepfake images and videos employ some type of face swapping technology. You've probably experienced this kind of technology already — faceswapping filters like on Snapchat, Instagram or Tiktok use technology similar to diffusion models, recognizing faces and replacing things in real time. "It will find the face in the image and then cut that out kind of, then take the face and convert it to its internal representation," Hansen said. The results are refined then repeated frame by frame. The future and becoming our own detectives As deepfakes become more and more realistic and tougher to detect, understanding how the technology works at a basic level can help us prepare for any dangers or misuse. Deepfakes have already been used to spread election disinformation, create fake explicit images of a teenager, even frame a principal with AI-created racist audio. "All the netizens on social media also have a role to play," Siwei Lyu said. Lyu is a SUNY Empire Innovation Professor at the University of Buffalo's Department of Computer Science and Engineering, and the director of the Media Forensics Lab. His team has created a tool to help spot deepfakes called "DeepFake-o-meter." "We do not know how to handle, how to deal, with these kinds of problems. It's very new. And also requires technical knowledge to understand some of the subtleties there," Lyu said. "The media, the government, can play a very active role to improve user awareness and education. Especially for vulnerable groups like seniors, the kids, who will start to understand the social media world and start to become exposed to AI technologies. They can easily fall for AI magic or start using AI without knowing the limits." RELATED STORY | AI voice cloning: How programs are learning to pick up on pitch and tone Both Lyu and CivAI believe in exposure and education to help combat any potential misuse of deepfake technology. "Our overall goal is that we think AI is going t impact pretty much everyone in a lot of different ways," Hansen said. "And we think that everyone should be aware of the ways that it's going to change them because it's going to impact everyone." "More than just general education — just knowing the facts and having heard what's going to happen," he added. "We want to give people a really intuitive experience of what's going on." Hansen goes on to explain CivAI's role in educating the public. "We try and make all of our demonstrations personalized as much as possible. What we're working on is making it so people can see it themselves. So they know it's real, and they feel that it's real," Hansen said. "And they can have a deep gut level feel for tthe impact that it's going to have." "A big part of the solution is essentially just going to be education and sort of cultural changes," he added. "A lot of this synthetic content is sort of like a new virus that is attacking society right now, and people need to become immune to it in some ways. They need to be more suspicious about what's real and what's not, and I think that will help a lot as well."

December 4 - The Philadelphia Flyers are playing their best hockey of the season, but a fresh challenge awaits Thursday when they host the defending champion Florida Panthers. Philadelphia is 4-0-1 over its last five games with three overtime wins during that stretch. Rookie winger Matvei Michkov has scored OT goals in two of those victories. The 19-year-old Russian has three OT tallies in the last nine games, including Saturday's 3-2 win at St. Louis. "We've had some confidence with (overtime)," Philadelphia coach John Tortorella said. "Michkov has helped us quite a bit there. Last year, we struggled with it." The Flyers have had a nice break since Saturday's victory, though, so it remains to be seen if their recent momentum will carry over into Thursday's contest. One area that could help against Florida is the potential return of No. 1 goaltender Samuel Ersson, who has been out since Nov. 11 with a lower-body injury. Ivan Fedotov and Aleksei Kolosov have split time in net during Ersson's absence with mixed results. Tortorella is grateful for the opportunity to evaluate both of his team's backup goalies, but he also wants to continue assessing Ersson, who is in his first full season as a team's primary netminder. "All this stuff with the injuries, the goalie, our No. 1 guy gone, it gives us an idea of what we have," Tortorella said. "And that's a big part of this year and, quite honestly, next (year) because there are no free agents coming. We have to keep on evaluating what we have in the organization." Florida, of course, knows what it has in its top goalie, Sergei Bobrovsky. However, the Russian netminder has been out lately while awaiting the birth of his child. He likely will miss Thursday's contest, as well, which could mean another start for Spencer Knight. Knight allowed five goals on 16 shots in Tuesday's overtime loss to the Pittsburgh Penguins that left Panthers coach Paul Maurice with mixed emotions. "It was alright. I think that's how we felt about it," Maurice said. "I don't think we gave up a tremendous amount. I don't think we took advantage of some things that we normally do. I'm not 100 percent sure how I feel about that one." After winning their previous three games by a combined margin of 17-4, the Panthers trailed the Penguins 4-1 with under 14 minutes remaining. However, Matthew Tkachuk registered a goal and two assists in the third period to help force the extra session before his team ultimately fell short. "I guess it's a point that we're happy to get," said Tkachuk, who finished with two goals and two assists to surpass 600 points for his career. He now has 603 in his ninth season. "But when we fight back, you just really want to get that win." Joining Tkachuk with a multi-point effort was Jesper Boqvist (two assists), while his brother Adam Boqvist was among the other goal scorers for Florida. "We just know when we go out there that we can wear teams down," Adam Boqvist said. "I think we almost showed that tonight with the third period. Just move on from this." The Panthers defeated the Flyers 4-3 in a shootout last month in Florida. The teams will meet again Jan. 13 in Philadelphia. --Field Level Media Our Standards: The Thomson Reuters Trust Principles. , opens new tab

Biden makes last-ditch ask of Congress for $24 billion to help Ukraine: reportAfter Juan Soto's megadeal, could MLB see a $1 billion contract? Probably not soonIt's great to see that a game as old as pinball—which first appeared at least in some form way back in the 1700s—can still learn a few new tricks. In this case it's via Pinbleton Park , an open world adventure developed by Turtlesoup Games, where you don't need a pinball table to play pinball: you can use the world itself. I'm not sure I'd appreciate walking outside my house and seeing my entire neighborhood had been transformed into a massive pinball game with bumpers, flippers, and a giant ball bouncing off buildings and rooftops. But the people (well, the animal people) of Pinbleton Park seem just fine with it. Check out the trailer revealed today at the Wholesome Snack showcase: I don't quite get the story from the quick description on the Steam store page, but apparently an evil corporation wants to destroy the forest and you can only stop them by finding "lost spirits" and using them to play pinball all over the place. Odd, but let's face it: that makes more sense to me than whatever the heck is going on in Death Stranding. How all this pinball helps the town isn't quite clear, but in one scene you can see a messy pinball game taking place inside a house, where the ball, as it bounces off the walls and bookshelves, splashes colorful paint everywhere. This makes a small bear very happy, and that's really all I need to know. I'm all for pleasing bears by making a mess with some paint. Pinbleton Park bounces our way in 2025. Here it is on Steam if you want to flip it onto your wishlist.
