深度学习往往被视为数学博士和大型科技公司的专属领域。但正如这本实践指南所展示的那样，熟练使用Python的程序员只需很少的数学背景、少量的数据和最少的代码，就可以在深度学习方面取得令人印象深刻的成果。怎么样才能做到？使用fastai，这是首个为最常用的深度学习应用提供一致接口的库。
本书作者Jeremy Howard和Sylvain Gugger是fastai的创建者，他们向你展示了如何使用fastai和PyTorch在各种任务上训练一个模型。你还将逐步深入了解深度学习理论，以便充分理解幕后的算法。
在计算机视觉、自然语言处理、表格型数据和协同过滤中训练模型；
学习在实践中至关重要的最新深度学习技术；
通过了解深度学习模型的工作原理，提高准确性、速度和可靠性；
了解如何将你的模型转化为Web应用；
从头开始实现深度学习算法；
考虑你的工作所带来的道德影响；
从PyTorch联合创始人Soumith Chintala的前言中获得启示。
