Must watch: NYT just released a damning forensic analysis of the ICE shooting in Minneapolis. It flatly refutes Trump administration claims — confirming the motorist was driving away, not toward the officer, and the officer was not hit by the vehicle. nytimes.com/video/us/10000…

@Derek_Vis_Nerd Neat!

Preprint: It's been suggested that Aphants may be able to visualise, but lack insight, as they can do Mental Rotation (MR) tasks. Instead, we show MR tasks are a weak measure of the propensity to visualise. biorxiv.org/content/10.110…

I’m scared abt the grandparents that’ll get scammed, but I’m not scared for the younger generation. They’ll adjust their expectations and favour real people / faces.

@nataliepeluso I feel this in my bones. Who knew research had the same kick as performing?!

Dynamic diffusion deepfakes are finally here. Microsoft releases VASA-1, which generates a realistic video from audio in real time, using a single portrait photo. Considering it generates its own "biological" movement, I'd say it's pretty impressive. Uncanny, but impressive.

@GntknB I’m sorry for your loss 🤍

Anneannem bu sabah hakkın rahmetine kavuştu... Güçlü olmayı, meraklı olmayı ve pes etmemeyi ondan öğrendim. Hoşçakal güçlü, güzel cerkes kızı Hoşçakal anneannem , beni büyüten annem Seninle büyümek çok özeldi. Allah'ım cennetine kabul etsin Nur içinde huzur içinde uyu Ben senin canın,sen benim canım Kızının emanetine iyi baktın bir ömür boyu, sanıyorum ve umuyorum ki ben de seni çok üzmedim..

@Dr_N_Butcher Yep, that seems to be the issue. Morphs make all expression features move at the same time and rate (usually linear), but any disruption to natural movement looks off.

@Casey_Becker This mirrors what we see in face identification comparing natural dynamic to non natural motion. The dynamic advantage isn’t so greatly observed if the natural temporal dynamics of the motion is altered e.g., speeded or slowed or reversed

First experiment from my PhD! Dynamic faces are great, but videos are a nightmare for experimental control, so many of us use dynamic morphs of photos. Except we showed that if you can’t use videos with natural face motion, you might be better off using static faces 😬 rdcu.be/dx9K5

@ufangyang I think they skew results quite a bit tbh. The naturalistic motion they remove is an important feature of emotional expressions. There are some good video databases that are controlled enough for most research :) Unless you're doing certain EEG research, then deepfakes can help!

@Casey_Becker Very interesting. How do you think the differences between dynamic morphs and static faces impact the ecological validity of emotion recognition studies? any suggestions for balancing experimental control with the realism needed to study natural facial expressions effectively?

@mzloteanu Agreed, videos should be used a lot more. Some experiments don’t have room for a time dimension, and videos can be tricky for EEG, so statics can be useful.

@Casey_Becker My question is "experimental control for what?" Videos offer ecological validity, and, depending on the affective framework you operate in, the only way to study emotion perception.

I am looking for a #postdoc, who has experience in conducting EEG exp and interested in how the brain compress information. #jobopportunity please contact me for further details. The position is at least for one year at @sabanciu with possibility of extension.

@TheRealJaffman Thank you for these kind words

Casey, my prayers with you. Try not to put extra burden on yourself. Parents, like mine, lived in an era that kept things hidden. Be well. Please know he is so proud of you.

My dad died shortly before I graduated, so turning up was hard. He'd tell anyone who'd listen about me, and read my papers even though I told him not to. I wish I’d known he needed to talk about the things on his mind, all the things that fill the journals that he left behind.

I had a great time being a part of the AI symposium at @ACNS_Official this year, thank you @TGrootswagers & Patrick Cooper for inviting me, and @astrid_zeman for joining me. I also did a lil poster, that was fun too.

@akbobak I too am chief word-cutter, commander of conciseness. I feel for you. It’s time to kill your darlings.

Gutted. If white Australia felt uncomfortable about the Voice part of the Uluru Statement, just wait until we get to the Truth Telling bit

I can’t believe anyone would say no to this. #VoteYes #Referendum2023 #ConstitutionalRecognition #VoiceToParliament
