    "# 百度2026CTI：生成式推荐广告排序推理性能优化\n",
    "\n",
    "> 报名链接：[https://aistudio.baidu.com/competition/detail/1461](https://aistudio.baidu.com/competition/detail/1461/0/introduction)\n",
    "\n",
    "##  赛道概要背景：\n",
    "\n",
    "传统广告排序模型已难以满足个性化推荐需求，生成式广告排序模型凭借强大的序列建模与语义理解能力成为行业趋势。该类模型依托 Transformer 架构，能深度挖掘用户点击、转化等超长行为序列中的长距离依赖关系，精准捕捉用户兴趣演化规律，从而生成更具吸引力的个性化广告内容，提升广告点击率与用户体验。但在实际应用中，存在很多挑战，如模型参数规模大、注意力计算复杂、存在超长历史序列、量化影响推理精度等。\n",
    "因此，本次赛事聚焦于如何提升生成式广告排序的推理性能，我们期待参赛选手能够从框架优化、算法创新、高性能计算等多个角度出发，提出突破现有技术瓶颈的创新方案。\n",
    "\n",
    "本次任务提供百度商业真实的用户行为数据、广告信息，选手需要在保证模型推理效果的前提下，极致优化推理性能。\n",
    "\n",
    "## 数据集介绍：\n",
    "\n",
    "1. 用户行为数据：包括全局唯一的日志ID和用户ID、广告曝光时间、广告点击时间等信息；\n",
    "2. 广告内容：包括广告的文本描述、图片信息、广告主信息等；\n",
    "3. 上下文信息：包括用户的地理位置、职业、性别、设备类型等；\n",
    "4. 用户统计信息：包括用户的活跃度、兴趣标签、历史点击率等统计数据。\n",
    "\n",
    "数据示例（按行字段，时间戳格式为Unix Timestamp）：\n",

    "\n",
    "## 评估指标\n",
    "\n",
    "1. 推理效率评估：参赛者提交inference脚本后，会通过统计inference脚本的运行时间，来计算在测试集上单条样本的平均推理时间。推理效率打分采用如下公示，如平均推理时间超过定义的时间限制，则本项和最终得分为0：\n",

    "\n",
    "2. 策略效果评估：综合考虑AUC及PCOC指标，PCOC需满足[0.85, 1.15]，AUC需满足[0.65, 1]，方可进入榜单排序，否则本项和最终得分为0，具体规则如下：得分由pcoc和auc组合而成：\n",
