Beyond the L2L challenge, our aim is to provide a valuable data and code resource for benchmarking algorithms on a wide range of medical tasks with standardised data splits.

We want to make CD-FSL accessible to MICCAI folks, and medical imaging accessible to ML folks! 🤖👩‍⚕️

The winners of the challenge will be awarded a 1000 CAD cash prize generously funded by ImFusion (https://imfusion.com)

Along with the dataset, we’re releasing two #PyTorch toolboxes for data handling and cross-domain few-shot learning to help participants kick-start their submissions, and make CD-FSL more accessible to the community! 🚀
The L2L challenge is focused on Cross-Domain Few-shot Learning. CD-FSL approaches such as meta-learning offer the potential to exploit similarities between different datasets to learn previously unseen tasks more efficiently. However, CD-FSL is underexplored in medical imaging.

We are delighted to announce the #MICCAI Learn2Learn challenge! 🎉

Download and explore our dataset of 28 unique tasks derived from 17 medical image datasets & create algorithms that learn new tasks with minimal annotated examples!

How to make business trips more climate friendly — MACHINE LEARNING for science

A meeting in Vienna, a lecture in Boston, a conference in London – academic events such as these are a part of researchers’ everyday working lives. In the following, some of our researchers and scholars share their experiences on the road and reveal their motivation to approach business trips in a more climate-friendly way.

MACHINE LEARNING for science

Taking a closer look at this paper, I really dislike it.

It's clear that newer papers *must* have a lower “disruption” score than older ones under a null model — they even confirm this in the supplemental material with a randomization test. It's an artifact of their definition.

When comparing with the null model they compute only the z-score, getting values at most 4 or so. It's also besides the point — as usual, small meaningless deviations from the null model can be statistically “significant.” Effect size ≠ statistical significance.

Finally, according to their definition, review papers would be “disruptive” because they funnel a bunch of citations. And a paper that does not cite anyone but is universally cited would not be “disruptive”. 🤷

Papers and patents are becoming less disruptive over time - Nature

A decline in disruptive science and technology over time is reported, representing a substantive shift in science and technology, which is attributed in part to the reliance on a narrower set of existing knowledge.

Working on a paper draft and I have to say that #ChatGPT is finding a real place in my workflow for improving the wording of a hastily composed first draft.
