The hardest part of building an LLM scoring tool isn't the model — it's the rubric. HackerRank open-sourced theirs. I read it, ran it, and faked a few resumes to test it.
Hey r/robotics ! After months of design and testing, I finally have a working 5-axis robot arm fully printable in PLA or PETG — no CNC, no laser cutter, just your printer. Here's what makes it different: - 5 axes (shoulder, elbow, wrist, gripper + base stepper motor) - ESP32 brain — totally open-source firmware - Electronics BOM under $100 sourcing parts yourself - Full wiring diagrams, assembly guide, and source code included The V1 is already fully operational and tested. I just launched a Kickstarter pre-launch page to fund the V2 (better rigidity, internal cable routing, improved gripper). Happy to answer any questions about the design choices, print settings, or the electronics. AMA! https://www.kickstarter.com/projects/pancoarmmk01/panco-arm-mk-01 submitted by /u/ConferenceFew7697 [link] [Kommentare]
I am studying the LoRA paper and have trouble understanding this figure. The function essentially measures how much of the subspace spanned by the top i vectors is contained in the subspace spanned by the top j vectors in the higher rank matrix. Therefore, j can not be lower than i. So when they say the 3rd and 4th figure zoom in on the lower-left triangle of the 2 left-most figures, how are there values for j=1 and i equals 2 to 8? I dont understand what kind of y-axis the 2 right figures are supposed to be using. Thanks in advance! submitted by /u/BelzebubReincarnated [link] [Kommentare]
