NLP随笔(四)
70 年代以后随着互联网的高速发展,语料库越来越丰富以及硬件更新完善,自然语言处理思潮由理性主义向经验主义过渡,基于统计的方法逐渐代替了基于规则的方法。

Building deep retrieval models
In the featurization tutorial we incorporated multiple features into our models, but the models consist of only an embedding layer. We can add more dense layers to our models to increase their expressive power. In general, deeper models are capable of learning more complex patterns than shallower models. For example, our user model incorporates user ids and timestamps to model user preferences at a point in time. A shallow model (say, a single embedding layer) may only be able to learn the simplest relationships between those features and movies: a given movie is most popular around the time of its release, and a given user generally prefers horror movies to comedies. To capture more complex relationships, such as user preferences evolving over time, we may need a deeper model with multiple stacked dense layers.

Taking advantage of context features
In the featurization tutorial we incorporated multiple features beyond just user and movie identifiers into our models, but we haven't explored whether those features improve model accuracy.

Using side features: feature preprocessing
One of the great advantages of using a deep learning framework to build recommender models is the freedom to build rich, flexible feature representations.
