「Code China」是独立第三方的开源内容托管平台,其上有很多的开源项目,若单凭搜索等手段去查找优质的项目是低效的,开源爱好者善于精准高效的获取自己想要的信息,基于此,Code China 从产品层面做了很多的实用功能,其中「最多 Star」 和「热门」项目榜单两大功能,分别把长期以来 star 数最多的项目和一段时间内最热门的项目以更直观的方式呈现给每个开源爱好者。
当前互联网上 IT 技术资料繁杂,进入某个领域学习某项技术,可能根本就不缺对应的资料,但是对于职业发展这块儿,相信很多初学者或者刚入门的人,对于自己今后的发展路线不甚清晰。CSDN 作为全球最大的中文开发者社区,同时在国内也有最大的开发者用户群体,为了更好的服务开发者,CSDN 联合阿里、字节跳动等企业以及技术专家打造了 IT 技术人才路线图,并在 Code China 上开源,希望吸引更多的专家和企业加入,对已有领域的图谱进行完善,或对未有的领域贡献图谱。图谱根据程序员职业发展规划,分为前端、后端、DevOps、测试、安全、云原生、AI、音视频、区块链等。
The Keras Tuner is a library that helps you pick the optimal set of hyperparameters for your TensorFlow program. The process of selecting the right set of hyperparameters for your machine learning (ML) application is called hyperparameter tuning or hypertuning.
This notebook classifies movie reviews as positive or negative using the text of the review. This is an example of binary—or two-class—classification, an important and widely applicable kind of machine learning problem.
TensorFlow is an end-to-end open source platform for machine learning
TensorFlow makes it easy for beginners and experts to create machine learning models. See the sections below to get started.
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 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.
One of the great advantages of using a deep learning framework to build recommender models is the freedom to build rich, flexible feature representations.
In this tutorial, we build a simple matrix factorization model using the MovieLens 100K dataset with TFRS. We can use this model to recommend movies for a given user.
This tutorial shows how to load and preprocess an image dataset in three ways. First, you will use high-level Keras preprocessing utilities and layers to read a directory of images on disk. Next, you will write your own input pipeline from scratch using tf.data. Finally, you will download a dataset
Real-world recommender systems are often composed of two stages:
1. The retrieval stage is responsible for selecting an initial set of hundreds of candidates from all possible candidates. The main objective of this model is to efficiently weed out all candidates that the user is not interested in.
This short introduction uses Keras to:
1. Build a neural network that classifies images.
2. Train this neural network.
3. And, finally, evaluate the accuracy of the model.
