A user says Sheridan's attention-bundle OV technique is closely related to the Jacobian lens, describing a linear relation decomposed along one causal axis.
AI
A user credits Sheridan Feucht with pioneering a technique that summarizes attention-head-bundle OV transforms. The user says it gave much better readouts than a logit lens in a vision-language model.
AI
A researcher sharing a new preprint says they used the heads to create a simple logit lens for image tokens after finding they were responsible for OCR in vision-language models.

One post argues it’s a great time to pursue an AI PhD. Another says it’s an excellent time for many people to research advanced AI’s societal impacts, but is less certain the traditional PhD format suits many today.
AI
One post argues that most universities are missing AI’s implications, predicting wider access to experience-based knowledge and a renaissance for teamwork, communication and leadership.

One post recommends taking classes to a student center after lectures for a large peer homework group, saying, “We did this; it was glorious!”
AI
A user argues that mathematics’ biggest impact will come from proofs for software, not the millennium problems, and sees automated research loops as a way to tackle verification at a billion-line scale.
