All models are wrong and yours are useless: making clinical prediction models impactful for patients

An insightful read on why machine learning models fail to help in the clinic.

The 5 key observations:

1. Success in academia ≠ success in the clinic.

Academic success = papers, grants, citations.

Clinical success = how often is your model being used in how many hospitals? how many patients does it help?

These incentives don't always work in the same direction.

2. Successful models use data available in routine practice.

Academics use rich datasets that most clinics simply don't have access to on their patients.

The academic view of an important step forward (spatial, multi-omics!), is not grounded in clinical reality.

3. Successful models are linked to actions.

Some academically interesting models are unhelpful in the clinic. Some people do better and others do worse, so what?

Doctors care about: what action should we take to help a particular patient? what drug, if any, should we give them?

4. Successful models are implemented outside of centers of excellence.

Helping research-savvy clinicians in Cambridge, Stanford, or Zurich is great. But the most impactful tools need to help the majority of doctors elsewhere too.

5. Success in the clinic is hard earned.

Hospitals are conservative, highly regulated environments. You must produce heaps of evidence before any hospital would even consider applying your academic insights.

It takes hard work to make tools from academia useful to patients.

Quilt is building AI assistants for solutions teams.

Quilt’s core products are AI-powered assistants designed to help solutions engineers with tasks like filling out requests for proposals, answering basic technical questions and prepping for demos.

The assistants can complete security and due diligence questionnaires, field questions from reps via Slack and summarize the contents of notes, calls and research ahead of customer meetings.

Quilt is uniquely able to incorporate engineers’ technical knowledge and “understand context.”

Researchers build throat patch for voice disorders

A team at the University of California, Los Angeles has designed an adhesive patch that can turn throat movements into speech — a step toward addressing challenges faced by patients with dysfunctional vocal folds.

Detailed in a new paper in Nature Communications, the patch converts throat muscle movements into electrical signals and sends them to a machine-learning model that matches them to specific words. Eventually, the technology and adhesive material — developed by UCLA researchers in 2021 — could help people speak without vocal folds.

MindEye2 preprint is out

Researchers reconstructed seen images from fMRI brain activity using only 1 hour of training data.

This is possible by first pretraining a shared-subject model using other people's data, then fine-tuning on a held-out subject with only 1 hour of data.

Past work trained independent models per person, with each person needing dozens of hours of training data in the MRI machine for good results.

It's now possible to get high-quality recons from a single visit to the MRI facility!

AI/ML-powered precision medicine startup Zephyr AI lands $111M

Zephyr AI’s work focuses on curating large datasets that it combines with AI algorithms to build tools and products for the healthcare industry. Presently, the company is developing improved data federation tools – applications that take data from multiple sources and convert them into a common model – and machine learning algorithms.

The company’s current target areas are in oncology and cardiometabolic diseases.

Meta deployed an AI powered software engineer like Devin at scale

This is the future of software engineering as proved by its 73% success rate.

In their new paper Meta introduced an AI powered software engineer called TestGen-LLM that focused on writing unit tests.

The new tool had a 73% approval rate from human engineers in code review.

TestGen-LLM is built with the philosophy of Assured LLMSE(LLM software engineering) which means complete automation with the assurance that the code has passed through a process ensuring it is high quality.

Meta believes this is the future of software engineering.

Neuralink has livestreamed a video of their first brain chip patient playing chess with their mind.

But some scientists don't see anything interesting in the demonstration.

Mikhail A. Lebedev, PhD, who was previously a Neuralink consultant, told our Telegram channel his vision based on the results of watching the demonstration.

“It’s nice to see that the patient is healthy after surgery. His dogs are cute too.

As for his ability to move the cursor around the screen with brain activity, this is not very convincing.

First of all, the neuronal activity that they write is not shown. What is the recording quality? How many channels? What kind of signal? Neither neuronal activity nor its change over time is shown. Within two months after surgery, most electrodes most likely stopped recording the activity of individual neurons.

Secondly, there is no analysis of the quality of task completion.

If we think backwards, since we haven’t shown neuronal activity, there’s nothing to see there. And it is quite possible that the chip records only artifacts, for example, electromyographic ones from the facial muscles.”

Meta introduced SceneScript, a novel method for reconstructing environments and representing the layout of physical spaces

SceneScript is able to directly infer a room’s geometry using end-to-end machine learning and represent it using language.

SceneScript uses next token prediction like an LLM, but instead of natural language it predicts architectural tokens. To train it, researchers created a synthetic dataset of 100,000 unique indoor environments.
