Recently in baidu, taobao app, such as a whim to send this post, to welcome you all to evaluate or ridicule,

His vomit first for fast:

Baidu and taobao recommend basically is recommended by users to access records related items recently, several Indian news on baidu search, the App on the news is full of India, make I am speechless, on taobao buy a dehumidifier, the results open the taobao, seventeen are dehumidifier, ask again after a user to buy the dehumidifier will buy a probability of large? !!!!!!!!!

Personal think each big long recommendation system are obviously fitting for a certain type of information, and for the relevant category information, reverse category information and reasoning information all have no good extensibility, such as a user to purchase a dehumidifier, can also be recommended to the desiccant, absorbent cloth, vacuum compressed bags and other products, rather than blindly to recommend dehumidifier,
