Tom SweeneyHOST
Exactly.
Tom SweeneyHOST
So the chute's like U-shape.
Tom SweeneyHOST
So it's like a slapstick thing where it's like...
Tom SweeneyHOST
Oh, clever.
Herman PoppleberryHOST
And the follow-up work found it's not just a capacity problem.
Herman PoppleberryHOST
It's a U-shaped attention bias that's intrinsic to how these models were trained.
Herman PoppleberryHOST
Tokens at the beginning and end get higher attention regardless of relevance.
Herman PoppleberryHOST
The calibration mechanism they built improved retrieval by up to 15 percentage points.
Herman PoppleberryHOST
When token embeddings cluster too tightly, the model can't distinguish alternatives, so it picks the same one again.
CornHOST
So when Daniel sees the script agent repeating itself in the middle of an episode, what he's seeing is the interaction of three things.
CornHOST
A U-shaped attention bias that starves the middle of the input, a decoding process that falls back on repetition under uncertainty, and a training corpus that taught the model repetition is safe.
CornHOST
The context
Myke HurleyHOST
And then the pen itself, very easy to disengage.
Myke HurleyHOST
Shape-wise, it's very similar to the Uniball 1P, which I really like.
Myke HurleyHOST
um it's a little shorter than that pen but not in a way that is a problem um and i i find it really nice to to use like it's comfortable to use to me it will be a pen i hang from a bag or something like that and like just like a perfect kind of product for that
Brad DowdyHOST
Yeah, and just to cover myself off here, once I got it in hand, I understood it.

Gary ParrHOST
And then I just, I just toss it.
Gary ParrHOST
I fold it U-shaped.
Gary ParrHOST
I'm showing you a U-shaped fold here so that you ... 'cause it's hard-
Beth EllicottHOST
Very nice
Gary ParrHOST
... to understand U-shape, you know, so I show it, demonstrate it.
JonathanHOST
It feels like fear, but it's actually hyper-focus.
JonathanHOST
And according to the Yerkes-Dodson law, which models the relationship between physiological arousal and cognitive performance as an inverse U-shape, a sudden increase in arousal can actually dramatically improve your performance, provided that your initial attention level was low.
JayHOST
So if you are doing a monotonous routine task, the sudden threat of a potential loss snaps you to attention and actually makes you execute the task better.
JayHOST
Let's look at the real-world examples Yakim and Hochman pointed out, starting with professional golf.
speaker_2HOST
Without a stable schema, the fast track failed and the memory was lost.
speaker_1HOST
Okay, that docking mechanism is brilliant, but it doesn't mean having a schema guarantees perfect learning, right? What about the 2022 Quinn Virtual Kitchen study? The U-shaped memory thing.
speaker_2HOST
Ah, the U-shape.
speaker_2HOST
This is so important.
speaker_2HOST
Yes.
speaker_2HOST
And number three, expect the near miss to be the hardest thing to learn.
speaker_2HOST
The material that almost fits what you know is what gets lost in that U-shaped trough.
speaker_1HOST
Which all points back to Rumelhart and Norman's ultimate rule.
Dion SimmonsHOST
The only place that is essentially clear they haven't gotten to yet are the docks just below you, closest to you.
Dion SimmonsHOST
But all along the outsides and all by the building, essentially the three, the U-shape that is not the side you're on, filled with McNabs.
Dion SimmonsHOST
On to the teeth.
JasonPANELIST
You want to fling me
Brent GarganoHOST
Which has not historically been the case.
Brent GarganoHOST
They even point out in here that in the past, they've expected this kind of U-shaped curve where younger people were really happy.
Brent GarganoHOST
And then as you get into your midlife, you start to deal with... jobs and kids and aging parents and all of these things and then as you start to get older you start to flourish again so to speak but what they really found was that kids children are not flourishing like they used to
Ben JonesHOST
now I'm gonna put this on the list here so or on the chart so what you're talking about is this u-shaped curve so this is age and You know, the older you get.
Ben JonesHOST
That's what it looks
Brent GarganoHOST
like.
Brent GarganoHOST
Yeah, they say J-shaped rather than U-shaped.
Brent GarganoHOST
Yeah.
Lupita MontotoHOST
And we're just talking about different, um, um, geometrical, um, ¿qué serían? ¿Figuras?
Lina OwenGUEST
Ah, yeah, shapes like the- [risas]
Lupita MontotoHOST
Shapes, different shapes, right? Or when people just get, um, [carraspeo] the-- perdón, la tela-- dame un minuto.
Lupita MontotoHOST
When they can have, you know, they already design it, um, materials-
Lina OwenGUEST
Mmm, mhm
