The R-sequence is another type of low-discrepancy sequence based on specially chosen irrational numbers[10]. It is similar to interleaved gradient noise but is simpler to compute and possibly more effective as a dither, particularly when augmented with a triangle wave function as demonstrated:
第二是事件聚类去重。对所有内容做 Embedding 向量嵌入（用的 text-embedding-3-small，非常便宜），计算相关性，剔除针对同一个主题、不同信息源的重复内容。这里有一套三级通知降噪机制：相似度低于 0.85 的视为全新事件，完整推送；0.85 到 0.97 之间的视为增量更新，只推送新增信息；超过 0.97 且实体高度重合的，直接静默。一个事件簇如果连续 7 天没有更新，会自动归档。
