Unverified衡量嵌入空间各向异性的指标包括平均余弦相似度（理想各向同性空间中应趋近于0）、有效维度/谱分析，以及IsoScore（给出[0,1]区间得分）68% similarVerifiedNumerical gradient checking approximates gradients using the central difference formula (f(θ+ε) - f(θ-ε)) / (2ε) and compares them with analytical gradients; a relative error below 1e-5 is considered correct, while an error above 1e-3 almost certainly indicates a bug.62% similarUnverifiedFP8 has two variants: E4M3 (4-bit exponent + 3-bit mantissa), which has higher precision and is suited for forward inference, and E5M2 (5-bit exponent + 2-bit mantissa), which has a larger dynamic range and is suited for gradient computation.56% similarUnverified一致性比率的衡量方法包括精确一致率、相邻一致率（允许±1分偏差）、Cohen's Kappa 系数，连续分数还可使用 Pearson 相关系数或 Spearman 等级相关56% similarUnverifiedFor double-precision floating-point numbers, one ULP near the value 1.0 is approximately 2^-52 ≈ 2.22×10^-16.55% similar
