    - 如何组网？答：paddle封装了大量的深度学习OP，用户可以根据需求设计自己的网络结构。
    - 训练数据如何组织？答：tdm的训练数据主要为：`user/query emb` 加 `item`的正样本，`item`需要映射到树的某个叶子节点。用户只需准备符合该构成的数据即可。负样本的生成，会基于用户提供的树结构，以及paddle提供的`tdm-sampler op`完成高效的负采样，并自动添加相应的label，参与tdm中深度学习模型的训练。
    - 大规模的数据与模型训练如何实现？答：基于paddle优秀的大规模参数服务器分布式能力，可以实现高效的分布式训练。基于paddle-fleet api，学习门槛极低，且可以灵活的支持增量训练，流式训练等业务需求。
