It’s a big day for central banks around the world today, so naturally Alphaville is tackling the big topics — like whether Rishi Sunak got some cowboy boots as PM and how much they cost. www.ft.com/content/82d2...
Could revealing Rishi Sunak’s cowboy boots ruin Brex-Tex relations?
There’s a Sunak in my boots!

I wrote about a crazy new LLM benchmark where the models are let loose on the crypto markets. Spoiler: sticking all in the prompt does not work that well in this case!

Come to our seminar with @wessel.ai on "Foundation Models for the Earth System", it's going to be a cracker! It's open to non-UCL people also.

Good to get some recognition for my incessant posting of Ben's blogs in the Alphaville comments section!
Testing the waters of finance blogging, I wrote about deep learning memes, random features, and the glory of kernel smoothing.
You keep using that word
Can you use deep learning memes to pick meme stocks?

Take note of the legal advice from Amnesty International and more detailed information from @netpol.org below. CND supporters should be aware that point 4 could impact on how supporters refer to non-violent direct action.

What news editors and politicians think people want: "Just tell them they'll get a tram somewhere in their city if they're nice."

What people really want: "SHOW ME THE FULL GPS ROUTE PLAN COMPLETE WITH LINKS TO THE WIKIPEDIA PAGES OF THE DISUSED RAILWAY LINES THAT COULD COME BACK INTO USE."

Cancer Research UK today published a report which highlights changes in cancer survival rates over the last 50 years.

Many headlines (like this one from the Guardian) have chosen to report the ‘doubling of cancer survival rates’ since the 1970s.

But that's misleading...

A new paper just dropped from Tri Dao(🐐)'s lab!

Here is my hot take!
Hardware-Efficient Attention for Fast Decoding
LLM decoding is bottlenecked for large batches and long contexts by loading the key-value (KV) cache from high-bandwidth memory, which inflates per-token latency, while the sequential nature of decodi...

the inexplicable core of Starmerism, as a truly new formation in world politics, is seeing governance as wholly an extension of general election campaign messaging
this is a very strange message from Starmer. First, you're boosting the far right which is, uh, risky. Second, your government was elected LAST YEAR why are you talking like the election campaign is under way?!?!!

it's very odd watching the election news in the UK when Labour still has *years* left on their massive governing majority

they can just ignore this stuff and create prosperity and get popular

and what's particularly weird is that it's not just commentators it's Labour themselves that don't get it

Stealing from X for clout, but someone bought a staggering 25% of the *entire* open interest of a semiconductor ETF (which is 20% NVDA) in a single OTM put option yesterday and today. $3.7 billion of underlying stock, 8ish delta, $23 mil of premium, so levered 15:1 betting on the NVDA embargo news.

I just came across this paper from ICLR 2024 which proposes an intricate combination of transformers and diffusion models to generate forecasts with these uncertainty bounds (red box), which are clearly inappropriate and could likely be outperformed by modelling the data as a random walk...

CUDA mode -> Triton mode
I've been diving into the "black magic" world of CUDA recently. More posts may follow, but I think we're at an interesting point. Perhaps the "CUDA moat" is under pressure and perhaps changing how we interact with GPU programming. 🧵
