昨天工作：

1. mv-dssm效果改善：mv-dssm重新设计商品图片和title信息融合获取融合特征的attention结构，当前新的网络的训练效果：acc = 0.767 auc = 0.767 precision = 0.859。
2. inference数据生成：图片特征提取完成。今天可以得到inference结果。

今天计划：

1. 对mv-dssm网络进行inference并进行结果分析。

2. 改善mv-dssm网络效果。

3. inference数据

drop table hs_tmp_363;
yes
create table graph_embedding.hs_tmp_363 as
select title, graph_embedding:return_concat_pic_feature_4(pic_ws) as pic_emb from graph_embedding.hs_tmp_pic_inf_1 group by title;

create table graph_embedding.hs_tmp_362 as select b.item_id, a.title, a.pic_emb from graph_embedding.hs_tmp_363 a join graph_embedding.hs_dssm_dic_title_inf_10 b on a.title=b.title;

create table hs_tmp_364 as select a.*, b.pic_emb as pic_ws from hs_tmp_267 a join hs_tmp_362 b on a.video_id = b.item_id;

2. inference

3. train

3. 添加multi_inf_attention测试
