SWARM INTELLIGENCE IN MEDICINE
***
Swarm learning, or swarm intelligence, is how swarms of bees or birds move in response to their environment.
When applied to data there is “more peer-to-peer communications, more peer-to-peer collaboration, more peer-to-peer learning and that’s the reason why swarm learning will become more and more important as … as the center of gravity shifts” from centralized to decentralized data.
Medicine Example:
Consider this example, “A hospital trains their machine learning models on chest X-rays and sees a lot of tuberculosis cases, but very little of lung collapsed cases. So therefore, this neural network model, when trained, will be very sensitive to what’s detecting tuberculosis and less sensitive towards detecting lung collapse.”
“However, we get the converse of it in another hospital. So what you really want is to have these two hospitals combine their data so that the resulting neural network model can predict both situations better. But since you can’t share that data, swarm learning comes in to help reduce that bias of both the hospitals.”
And this means, “each hospital is able to predict outcomes, with accuracy and with reduced bias, as though you have collected all the patient data globally in one place and learned from it.”
Moreover, it’s not just hospital and patient data that must be kept secure. What swarm learning does is to try to avoid or reduce the sharing of data, or totally prevent the sharing of data, to [a model] where you only share the insights, or you share the learnings.
So, that’s why it is fundamentally more secure.

SWARM TECH: A swarm of Sats
Swarm Technologies, which has launched 120 satellites to date, is a buzzy player in this niche market. It was acquired by SpaceX in early August, and before that it had raised $27.7 million.
One use case: SweetSense, which manages water and energy services in remote environments, spends $5 per device per month on Swarm’s data plan, and a flat $120 on its tiles, SweetSense CEO Evan Thomas told us. He said SweetSense used to spend $30 per device per month, and a flat $300 per radio, with legacy satellite provider Iridium.
The tradeoff is that CubeSats can only move small amounts of data. Swarm’s network normally operates at one to three kilobits per second, CEO and cofounder Sara Spangelo told us. Contrast that with Starlink, which transmits data at speeds anywhere from 50 megabits per second (MBps) to 150MBps.
Big picture: CubeSats have limited bandwidth by design, and this specialization was likely a major factor driving SpaceX’s purchase of Swarm a few weeks ago. As Swarm CEO Sara Spangelo told us days before the acquisition, “We’re not actually a direct competitor with Starlink.”
