Loss Functions in Perception
A loss function is what a neural network uses to measure how wrong a prediction was, and how that error gets punished. Two networks can be trained on the exact same data to do the exact same task and...

Picture a coach standing on the sideline, watching a match from one specific angle. Now picture a drone hovering directly overhead, watching the exact same match. Both are looking at the same 22 play...
Why Every Camera Needs a “Warmup,” Just Like a Football Team: Zhang’s Camera Calibration, from Scratch Before a football match starts, players don’t just stretch. They hit passes over a known distanc...
Beyond the Simulation: a weekly post, focused entirely on perception and learning-based robotics, the two areas I actually taken classes in, built projects and simply love exploring in robotics. The ...
When neural networks aren’t enough and you have to go back to old school methods. After we published Part 1, Lohith left a comment asking about the math and physics grounding behind MonoSense. Specif...
One camera feed. Real Tesla footage. A full 3D world. Tesla’s Bold Bet In May 2021, Elon Musk made one of the most controversial decisions in the history of autonomous driving. He removed radar from ...
I was having my morning cereal, and suddenly, out of the blue, this video pops up on my YouTube feed. https://medium.com/media/95939bad927b8bba970f5c8d08528095/hrefI didn’t even click the video, but ...
As I complete my first semester as a Graduate Student in Robotics Engineering at Worcester Polytechnic Institute (WPI), the journey has been nothing short of a roller coaster ride. Coming into my Mas...
Who am I? I thought this would be a good starting point for writing about myself and my interests. Who am I to you, the reader of this blog? I could be a friend or a football teammate, or as a roboti...
