Show HN: FeyNoBg – Automatic background removal model and training library Hey HN, I’m Shreyash from Feyn. We help companies build custom models from their data.<p>Today, we’re releasing FeyNoBg, an automatic background removal model. Alongside it, we&#x27;re open-sourcing NoBg, the Python library we built to train and run it.<p>Try the model here: <a href="https:&#x2F;&#x2F;huggingface.co&#x2F;spaces&#x2F;feyninc&#x2F;feynobg" rel="nofollow">https:&#x2F;&#x2F;huggingface.co&#x2F;spaces&#x2F;feyninc&#x2F;feynobg</a>.

We&#x27;ve all tried it at some point. Often it is to reuse the subject in a different artifact. Nowadays, it is common to make chat stickers out of it. It is one of the most common but under-appreciated uses of AI. It is also surprisingly complex. Models can be easily confused by camouflage, motion blur, or fine structures like hair.<p>The task requires two skills. First, a model has to identify the foreground. Second, it has to trace the foreground’s boundary and estimate an opacity value for each pixel. Generally, these skills are taught with different datasets. That creates a failure point. A poor training mix can improve one skill at the expense of the other. We saw this in our controlled evaluation. A training run with just the MaskFactory dataset improved on the CAMO benchmark but regressed on DIS5K.<p>For FeyNoBg, we took an interpretability-first approach to training. We first studied how BiRefNet’s stages contribute to finding the foreground and reconstructing its boundary. We discovered that the third stage of it&#x27;s feature extractor holds a lot of information. Both localization and boundary reconstruction depend heavily on the feature map produced here.<p>This led us to expand this stage from 18 to 24 blocks while preserving the pre-trained weights. We then trained FeyNoBg on 26.1K diverse examples assembled from 10 datasets. The goal was to improve foreground identification and boundary precision without sacrificing either one.<p>Across eight benchmarks, FeyNoBg achieves the best published score on four and comes within 2% of the leader on the rest.<p>Building FeyNoBg also exposed a tooling problem. Image matting models are usually released as isolated repositories with incompatible preprocessing, training, and evaluation code. We built NoBg to solve this. NoBg puts these workflows behind one Python interface. It supports BiRefNet today, with more architectures coming. We hope you build something exciting with it!<p>Happy to answer any questions!

Show HN: Dozenal – A Game of Spatial Arithmetic Hello HN! We&#x27;re Rory and Chris, and we&#x27;ve made a game called Dozenal[0], a grid-based number puzzle game where the objective is to use all the tiles on the board to create totals of 12 (hence the name).<p>We think the mechanic is quite unique, although keen to hear if people know of similar games! You essentially drag tiles across the board, and the distance between two numbers decides the arithmetic operation when they connect to each other: zero spaces is addition, one space is subtraction, two spaces is multiplication: e.g.<p>5 → 4 = 9<p>5 → _ → 4 = 1<p>5 → _ → _ → 4 = 20<p>We&#x27;ve spent the past month getting people to test the game. The two biggest points of feedback are: 1. People generally find the learning curve a little too steep -- we are open to any feedback on how to make the rules clearer or easier -- but we&#x27;ve found that almost everyone that sticks with it for more than a couple of days can solve the puzzles. 2. People find that &quot;mixing&quot; arithmetic is confusing -- you can combine up to two arithmetic operations (e.g. addition and multiplication) in a single chain to reach a &quot;12 total&quot;, but there&#x27;s a catch in that you can only do this for one move.<p>We release a new puzzle every day (all of them are set by Chris), and our aim is to make something that people enjoy coming back to and that strikes the right balance between a time-killer and a bit of a challenge.<p>A bit of backstory: Chris and I came up with the idea over a decade ago while we were students. We were always tinkering with prototypes but never released anything. AI coding assistants made it a lot easier to work on the game in the past couple of months (it&#x27;s a mixture of human and AI development, not fully vibe-coded).<p>Give it a try and let us know what you think!<p>[0] - <a href="https:&#x2F;&#x2F;dozenal.game" rel="nofollow">https:&#x2F;&#x2F;dozenal.game</a>

Show HN: Watch 14-Byte AI "brains" attempt to solve a 2D maze (Its hard) Hey HackerNews,<p>I built this project over the last few weeks as a palette cleanser from a failed game launch.<p>I wanted to learn a bit about AI&#x2F;Neural-Networks and naively thought I could build a tiny maze-solving AI in a weekend with a 100% solve rate.<p>Well - I couldn&#x27;t, but I got pretty close. 14 Bytes total model size, and a 96.5% solve rate on unseen mazes. Trained across 46 phases experimenting with different ideas to improve the model (better performance, smaller size).<p>Its quite fun to watch the model attempt to solve the maze, when they fail its usually due to getting stuck in a loop. The models have no access to coordinates, map-data, or external memory scratches - they must navigate using only immediate local neighbourhood observations.<p>There is a model dropdown and you can see how the model has progressed over each phase, constantly getting smaller and increasing its solve rate. Total trained models number in the thousands - I just expose the winning models from each phase.<p>Overall a fun experiment, with much implementation help from AI agents to scaffold and implement the code (I&#x27;m a lazy software dev).
