后来无奈只能含泪停下课程,先去苦读这本动物神书。 前前后后看了我三个月,总算全部好好的过了几遍,再回头看课程问题就觉得真心小儿科,这里就先把'Applied-Data-Science-with-Python/Introduction-to-Data-Science-in-Python'第三周课后代码发出来,供各位跟我一样还在PYTHON学习道路上奔跑的小伙伴们参考,一起努力!

这门课的Assignment前俩周还是使用Python+numpy来自己实现regularization, gradient checking和optimization. 第三周简单介绍了一下TensorFlow,并且使用TensorFlow来快速搭建一个Neural Network. 好像记得有个视频最后有比较长时间的空白,不过这个问题应该会很快解决掉,无伤大雅。评分依旧5颗星~~~撒花 第三门课是case stud...
make.power(3)生成了一个x^3的函数,而make.power(2)生成了一个x^2的函数。这里的n只会在函数定义的范围里去查找值,不会越过函数再继续查找。内置函数的Parent environment就是定义这个函数本身的函数。 据老师说,这样子的词法作用域,同时适用于python等较新潮的函数。或将成为未来编程界的主流。(compared with ...

吴恩达深度学习2-Week3课后作业-Tensorflow 一、deeplearning-assignment 到目前为止,我们一直使用numpy来建立神经网络。这次作业将深入学习框架,可以更容易地建立神经网络。 TensorFlow,PaddlePaddle,Torch,Caffe,Keras等机器学习框架可以显著地加速机器学习开发。这些框架有很多文档,可以随意阅读。在本次任务中,将学习如何在...
which we use to determine dependencies between input variables and outputs. We finalize with a collection of metrics to measure model accuracy, and continue with the introduction to the Python programming language. Please note, there is no formal assignment this week, and we hope that everyone par...
Here atClass Central, we get asked all the time whetherCourseracourses are really free. The Coursera user interface (UI) is designed to push learners towards Coursera’s paid offerings, and it may confuse new learners regarding what’s free on the platform and how to sign up for it. So ...
Students are able to absorb the information offered in lectures more attentively if they have been provided with a problem or an assignment to complete prior to the lecture. Students retain more information through the process of active learning instead of learning through listening to lectures. ...
Coursera-Introduction to Data Science in Python-week 3-Assignment 3 自己在边做这个作业的同时偶然发现自己百度了一波居然找不到大家有分享答案和讨论的地方,于是决定自己做好后发出来共享一下,同时大家可以讨论一下。 这个作业只是勉强通过了80分的及格线,因为时间紧(自己算错了时间导致申请下一个课程的助学金已...
