    We have started doing behavioral training with our subjects in this cage, and we can get them to do some basic foraging tasks.

    With this we can use clustering algorithms (here, UMAP), to automatically segment behavior into meaningful actions like sitting, walking, and climbing.

    It can track two interacting macaques.

    We will also share the model itself. It can do robust low error tracking of 13 joints at 30 Hz.

    The paper goes over the cool tricks we developed to overcome the annotation problem. The result is a library of effectively 200,000 images, which we will share with the public when the paper is accepted.

    We filmed a large number of videos and worked with Hive AI to annotate about 10,000 images.

    So we built a large pen in which rhesus macaques could move freely. We placed 62 machine vision cameras around the pen at precise positions and angles. The walls are chroma key green to aid in segmentation.

    Unlike humans, where there exist few large (million plus) annotated databases, nothing comparable works for monkeys. And the human networks don’t generalize - we tried! In our view, the annotation problem is THE major barrier to macaque tracking.

    It turns out macaque tracking is a LOT harder than tracking worms, flies, or birds. They are big furry monochrome blobs with very little articulation, they display a lot of poses, and they are basically acrobats.

    It’s a general solution to the problem of pose tracking macaques.

    Excited to announce our bioRxiv paper describing OpenMonkeyStudio. This is a BIG three-lab project that took a LOT OF people working very hard a lot of time.

    Excited to share my first paper! We show that it's really hard to tell if a subject integrated evidence to form their decisions and offer an approach for doing so.

  14. While DDMs are great for sensory evidence accumulation, they have odd restrictions in value based decision making. We played around a little and voila:
