我们再回顾一下 scikit-learn 机器学习地图, 在分类演算的区域第一个看到的是线性 SVC, 让我们对 digits 资料使用这个演算法试试看, 直接点选 Run 观察结果: 在这段程式中我们手动设定了gamma 参数, 但其实透过网格搜索(Grid search)或交叉验证(Cross validation)都可以自动找出合适的参数设定, 但这些方法并不是...

particularly for not very experienced developers. Scikit-learn has a much higher level of abstraction than TensorFlow, making the former a more user-friendly library for beginners. TensorFlow can be partly abstracted thanks to its popular Keras API, but still, it requires heavier coding and a more...
