What it does

Free online RSD Calculator instantly calculate Relative Standard Deviation, coefficient of variation, variance, and mean with full step-by-step working.

Paste a data set or enter a known standard deviation and mean — get relative standard deviation, variance and step-by-step working in milliseconds. Runs in your browser, nothing to install. Your RSD, standard deviation, mean, and full breakdown will appear here. Relative Standard Deviation (RSD) is the standard deviation expressed as a percentage of the mean. The formula is RSD = (s / x̄) × 100%. RSD is also called the Coefficient of Variation (CV) when written as a decimal, so the two terms describe the same quantity in different units. RSD is dimensionless. That property lets analysts compare variability across datasets that use different units, scales, or magnitudes concentration in…from rsdcalculator.com

  Needle: We Distilled Gemini Tool Calling into a 26M Model▲776

  Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
