Proud to partner with the Dept of Neurology at Cleveland Clinic to first benefit those that need it the most

[WIRED @WIRED]

The Cleveland Clinic and startup Piramidal are developing an AI model trained on brain wave data to monitor patients in the ICU. https://t.co/0om75Jxw05

@ashleymayer How much? Looking to get an office in the area in the next couple of weeks

@mariyaivasileva @Meta coffee at Abraço in East Village tomorrow 3pm? 🙂

Come help us decode the brain, nice. https://t.co/jEhjvEGqrV

Is it knowledge itself that drives our desire to learn, or just the neural response it invokes while learning it.

[Dimitris Fotis Sakellariou @dsacellarius]

@ceo_of_ai Yes, for when too.

Happy to announce our 6M funding round at https://t.co/fdhHqJVtiu, led by @LionheartVC and @Adverbvc.

Thank you @SurbhiSarnaSF, @snowmaker, @wcrosby and the rest of the @ycombinator community for steering us in the right direction.

[Y Combinator @ycombinator]

Congrats to the Piramidal team on the $6M seed!

Piramidal (YC W24) is building a first-of-its-kind foundation model that can detect and understand complex “brain language” or brainwaves.

Piramidal’s foundation model for brainwaves could supercharge EEGs https://t.co/aaY4QnS2K3

(17/25) Piramidal (https://t.co/smarTORqvr): A foundation model for understanding brain activity, trained on a “colossal and diverse corpus” of brainwave data. They’ve been able to train a large model with lower computational costs by dividing sequential EEG data into chunks.

[Y Combinator @ycombinator]

Piramidal (W24) is building a foundation model for the brain. Imagine ChatGPT but for the “language” spoken by your neurons.

Their first product is a copilot for epilepsy diagnosis that helps neurologists get insights around a patient’s EEG, in real-time: https://t.co/BL7czznM71

@lithium534 @_akhaliq Seems to break form me at Step 3 `vtoonify.load_state_dict`, with an error trace of `UnpicklingError: invalid load key, '<'.`.

📜🚨📜🚨
NN loss landscapes are full of permutation symmetries, ie. swap any 2 units in a hidden layer. What does this mean for SGD? Is this practically useful?

For the past 5 yrs these Qs have fascinated me. Today, I am ready to announce "Git Re-Basin"!

@MishaLaskin 🔥To add 1/ RNN also imposes step-wise dependencies 2/ Attention pooling can sit on top of RNN 3/ But superiority in Transformers lies with deploying self-attention combined w/ positional embedding so that calculation is parallelisable. That excess of compute allows for multihead
