Как модели упаковывают концепты в многообразия: смотрим на теорию, рушим идеальный мир и ищем кружочки
Mechanistic claims в interpretability для бедных, но бравых. Шучу, конечно. Просто когда дело дошло до задачи "придумать название" — вспомнила шутки моей коллеги. В одном из приближений можно сказать, что AI-модели обрабатывают входы послойно. На каждом слое модель выдаёт вектор , который можно читать как точку, центроид, область и так далее. Все эти точки, центроиды, области, направления кажутся абстракциями, но как только мы структурируем их — мы видим тонну прекрасного. Например, мы можем геометрически понимать и находить концепты , упакованные в многообразия . Что называется концептом, а что многообразием? Какие структуры образуют циклические компоненты и как откопать это в модели? Почему теория существует и находится эмпирически, но пока не машстабируется? На эти вопросы мы и покопаем ответы в данной статье.

🧠 How does the #hippocampus keep a spatial map stable while adding aversive context?
Miguel-López et al. show that in mice running on a linear belt, #CA3 #axonal population activity preserved a common spatial #manifold across baseline, air puff and probe sessions. The aversive cue did not erase the map, but deformed it, embedding affective information into the same #representational geometry:

🧠 New preprint by Garcia-Garcia et al.: The authors show that cerebellar #GranuleCells do not simply expand #cortical activity into a high-dimensional code. Instead, they preserve low-dimensional cortical #manifold geometry while reorienting it across contexts. This rotation separates similar tasks, reduces interference, and supports flexible dual-task learning.

For over five years the battery charger for our electric bicycle has been awkwardly dangling from a little hook.
With emotional support from toddler and actual support from #FreeCAD I finally created a simple wall bracket.
It's available from .stl sharing site #manifold :-)
Inner dimensions are 73mm by 42,5mm. With a hole in the bottom for a cable exit. Probably fits other chargers as well.

There's a great talk by Juan Gallego on how low-dimensional #NeuralManifolds arise from biological constraints, remain invariant across states and inputs, and support cross-animal alignment. Examples span #HeadDirection rings, #gridcell tori, #MotorCortex prep vs movement, striatal timing dynamics, and C. elegans #behavior loops. Cool talk as it shows how #manifold-level structure can generalize across tasks and organisms.
