From the difference with eager execution to graph capture, operator fusion, kernel lowering, static shapes, and memory planning — we walk through it step by step with diagrams and an interactive demo.http://blog.caveduck.io/posts/neural-net-pruning/Mon, 27 Apr 2026 00:00:00 +0000http://blog.caveduck.io/posts/neural-net-pruning/Starting from LeCun’s 1989 Optimal Brain Damage, this is the story of shrinking a model by cutting weights away (pruning). What to cut, how, and how much; the surprise of compression that survives even a 95% cut thanks to retraining; and the point that you only get a real payoff when the hardware (NVIDIA 2:4) backs you up — all with plots we measured ourselves on an MNIST MLP.http://blog.caveduck.io/posts/neural-net-quantization/Mon, 20 Apr 2026 00:00:00 +0000http://blog.caveduck.io/posts/neural-net-quantization/We take the trained 32-bit weights of a neural net and shrink them down to 2–8 bits using two approaches: K-Means (non-uniform) and Linear (uniform, integer arithmetic). From the affine mapping r=S(q−Z) all the way to the compression-ratio vs. accuracy trade-off, with plots measured by actually running the code on an MNIST MLP.http://blog.caveduck.io/posts/deep-learning-data-types/Mon, 13 Apr 2026 00:00:00 +0000http://blog.caveduck.io/posts/deep-learning-data-types/INT8, FP16, BF16, FP8 (E4M3/E5M2), FP4 — what do all these data types flooding deep learning model cards actually mean, and how do bits get interpreted as numbers? We take them apart one by one, with a widget where clicking bits updates the formula and value in real time.http://blog.caveduck.io/posts/welcome/Mon, 06 Apr 2026 00:00:00 +0000http://blog.caveduck.io/posts/welcome/Introducing the official Warpspace Blog - where we share our journey building Caveduck.iohttp://blog.caveduck.io/page/about/Mon, 01 Jan 0001 00:00:00 +0000http://blog.caveduck.io/page/about/About Warpspace Inc. and Caveduck.io
