It is built from many individuals, each making local, imperfect decisions.\u201d\u003C\/p\u003E\u003Cp\u003EWhen a predator threatens a herd of sheep, individuals near the edge often move toward the center to reduce their own risk, Bhamla explained. \u201cThis is \u2018selfish herd\u2019 behavior,\u201d he said. \u201cShepherds exploit that instinct using trained dogs.\u201d\u003C\/p\u003E\u003Cp\u003EFrom examining hours of contest footage, the researchers found that controlling small groups of sheep can be harder than managing large ones. A larger group, with more sheep protected in the center, may behave more coherently than a small group as the animals constantly shift between two instincts: \u201cfollow the group\u201d and \u201cflee the dog.\u201d\u003C\/p\u003E\u003Cp\u003E\u201cThat switching behavior makes the group unpredictable,\u201d said Tuhin Chakrabortty, a former postdoctoral researcher in the Bhamla Lab who co-led the study.\u003C\/p\u003E\u003Cp\u003ELooking closely at how dogs and their handlers guide small groups, the researchers found that unpredictability in the flock\u2019s behavior does not always make control harder. \u201cUnder the right conditions, that \u2018noisy\u2019 behavior might actually be a benefit,\u201d Bhamla said.\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ESuccessful Sheep Herding\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003ESheepdog handlers categorize sheep by how strongly they respond to a dog\u2019s threatening pressure. Some very responsive sheep might panic under too much pressure, while others might ignore mild pressure and require stronger positioning by the dog.\u003C\/p\u003E\u003Cp\u003EThe researchers observed that successful control often followed a two-step pattern. First, the dog subtly influenced the sheep\u2019s orientation while the animals were mostly standing still. Once the flock was aligned in the desired direction, the dog increased pressure to trigger movement. The timing of those actions was critical, because alignment within a small group could disappear quickly as individuals switched between instincts.\u003C\/p\u003E\u003Cp\u003E\u201cIn our simulations, increasing pressure makes the flock reach the desired orientation faster, but how long the flock stays aligned is set mainly by noise,\u201d Chakrabortty said. \u201cIn essence, dogs can steer the direction, but they can\u2019t hold that decision indefinitely, so timing matters.\u201d\u003C\/p\u003E\u003Cdiv\u003E\u003Cdiv\u003E\u003Cdiv\u003E\u003Cdiv\u003E\u003Cdiv\u003E\u003Cp\u003E\u003Cstrong\u003EDeveloping Computer Models\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003ETo understand the broader implications of that behavior, the team developed computer models that captured how sheep respond both to the dog and to one another. The models allowed the researchers to test different strategies for guiding groups whose members make independent decisions under uncertainty.\u003C\/p\u003E\u003Cp\u003EThey then applied those ideas to simulations of robotic swarms. Engineers often design such systems so that each robot blends signals from all nearby robots before deciding how to move. While that approach works well when signals are clear, it can break down when information is noisy or conflicting, Bhamla explained.\u003C\/p\u003E\u003C\/div\u003E\u003C\/div\u003E\u003C\/div\u003E\u003C\/div\u003E\u003C\/div\u003E\u003Cdiv\u003E\u003Cdiv\u003E\u003Cdiv\u003E\u003Cdiv\u003E\u003Cdiv\u003E\u003Cp\u003ETo explain why that switching strategy can work under noisy conditions, the researchers used an analogy of a smoke-filled room where only one person can see the exit, and no one knows who that person is. If everyone polls everyone else and averages the guesses, the one correct signal can get diluted by many noisy ones.\u003C\/p\u003E\u003Cp\u003E\u201cThat\u2019s the counterintuitive part. When only one person has the right information, averaging can wash out the signal. But if you follow one person at a time, and keep switching who that is, the right information can spread through the crowd,\u201d Bhamla said.\u003C\/p\u003E\u003Cp\u003EBuilding on that idea, the researchers tested a strategy inspired by the switching behavior they observed in sheep. In the simulations, each robot paid attention to just one source at a time (either a guiding signal or a neighboring robot) and switched that source from one step to the next.\u003C\/p\u003E\u003Cp\u003EUnder noisy conditions, this switching strategy required less effort to keep the group moving along a desired path than either averaging-based strategies or fixed leader-follower strategies.\u003C\/p\u003E\u003Cp\u003EThe researchers call their approach the Indecisive Swarm Algorithm. The name reflects a counterintuitive insight: allowing influence to shift among individuals over time can make groups easier to guide when conditions are uncertain.\u003C\/p\u003E\u003Cp\u003E\u201cOur findings suggest that the same dynamics that make small animal groups unpredictable may also offer new ways to control complex engineered systems,\u201d

And traditional physics-based models, such as Brownian motion, often fail to fully capture the complexity of unpredictable nanoparticle movements, which can be influenced by factors such as viscoelastic fluids, energy barriers, or surface interactions.\u003C\/p\u003E\u003Cp\u003ETo overcome these obstacles, the researchers developed a deep generative model (called LEONARDO) that can analyze and simulate the motion of nanoparticles captured by liquid-phase transmission electron microscopy (LPTEM), allowing scientists to better understand nanoscale interactions invisible to the naked eye. Unlike traditional imaging, LPTEM can observe particles as they move naturally within a microfluidic chamber, capturing motion down to the nanometer and millisecond.\u003C\/p\u003E\u003Cp\u003E\u201cLEONARDO allows us to move beyond observation to simulation,\u201d said \u003Ca href=\u0022https:\/\/vidajamali.github.io\/\u0022\u003EVida Jamali\u003C\/a\u003E, assistant professor and Daniel B.

LEONARDO uses a specialized \u201closs function\u201d based on known laws of physics to ensure that its predictions remain grounded in reality, even when the observed behavior is highly complex or random.\u003C\/p\u003E\u003Cp\u003E\u201cMany machine learning models are like black boxes in that they make predictions, but we don\u2019t always know why,\u201d Shabeeb said. \u201cWith LEONARDO, we integrated physical laws directly into the learning process so that the model\u2019s outputs remain interpretable and physically meaningful.\u201d\u003C\/p\u003E\u003Cp\u003ELEONARDO uses a transformer-based architecture, which is the same kind of model behind many modern language AI applications.
