- Finding the outline by blurring and votingHow a computer can split a noisy image into regions with one simple trick: blur the mask, then let every pixel vote.
- After 722 papers in one day, a case for understandingOpenAI released 722 math papers in one day, and mathematicians called for a boycott. I think AI should help us understand math instead, so I am starting a series that explains research in plain language.
