Question: What % of the data in the EMR is fabricated, inaccurate, inconsistent, irreconcilable? Ergo: Training the Models on medical records? mmh!

New 3h31m video on YouTube:
"Deep Dive into LLMs like ChatGPT"

This is a general audience deep dive into the Large Language Model (LLM) AI technology that powers ChatGPT and related products. It is covers the full training stack of how the models are developed, along with mental models of how to think about their "psychology", and how to get the best use them in practical applications.

We cover all the major stages:
1. pretraining: data, tokenization, Transformer neural network I/O and internals, inference, GPT-2 training example, Llama 3.1 base inference examples
2. supervised finetuning: conversations data, "LLM Psychology": hallucinations, tool use, knowledge/working memory, knowledge of self, models need tokens to think, spelling, jagged intelligence
3. reinforcement learning: practice makes perfect, DeepSeek-R1, AlphaGo, RLHF.

I designed this video for the "general audience" track of my videos, which I believe are accessible to most people, even without technical background. It should give you an intuitive understanding of the full training pipeline of LLMs like ChatGPT, with many examples along the way, and maybe some ways of thinking around current capabilities, where we are, and what's coming.

(Also, I have one "Intro to LLMs" video already from ~year ago, but that is just a re-recording of a random talk, so I wanted to loop around and do a lot more comprehensive version of this topic. They can still be combined, as the talk goes a lot deeper into other topics, e.g. LLM OS and LLM Security)

Hope it's fun & useful!

@Papa_Heme I don’t agree. I think medical books, UpToDate and OpenEvidence are complements depending on your needs. Sometimes we need to learn or review the basics, the whole organized chapter on x disease, sometimes we need the answer for a specific patient condition.

[A Arturo Rodriguez MD MBA @R2D2md]

@Acyn @drnic1 Agree with @SecKennedy. The decrease in morbidity and mortality seen in the past century was mainly due to improvements in urbanization, sanitation and basic medical interventions. The contribution of Antibiotics, vaccines and more advanced med treatments is much smaller.

No shit. We have little control over longevity. We have maximized lifespan. Genetics and environmental factors play in different proportions in different individuals. We have, though, some control on healthspan (how healthy we live). https://t.co/4SSRfsv568

@ValerieAnne1970 It was a fiasco! Yes, the most stupid request of the Century! It was NY governor Cuomo who requested 20 or 30 thousand Ventilators. Haha. It’s beyond comprehension.

@SecKennedy Congratulations and thank you Mr @SecKennedy , Mr @SecRubio and Mr @POTUS .
Good riddance! The WHO is a bureaucratic, incompetent, corrupt and politicized organization.
Next step is to make them accountable.

FDA is now open to Bayesian statistical approaches. A leap forward!

Bayesian statistics can help:
✅ Clinical trial design
✅ Finding the optimal dose
✅ Extrapolation to children
✅ Leveraging phase 2 results in phase 3

@newstart_2024 No. No way. Not even in the foreseeable future. @elonmusk

These Guidelines return us to the basics. American households must prioritize whole, nutrient-dense foods—protein, dairy, vegetables, fruits, healthy fats, and whole grains—and dramatically reduce highly processed foods. This is how we Make America Healthy Again.

Thank you, Mr. President, for standing up for children's health, gold standard science, and common sense.
