In this step-by-step tutorial, you'll build a neural network from scratch as an introduction to the world of artificial intelligence (AI) in Python. You'll learn how to train your neural network and make accurate predictions based on a given dataset.
而在标记图片或者进行图像识别时,我们经常使用卷积神经网络(CNN, convolutional neural network)。在进行语音识别、翻译等序列识别的时候,常用的模型为循环神经网络(RNN, recurrent neural network)。当面对自动驾驶等复杂问题时,我们可能会使用复杂混合网络(complex hybrid neural network architecture.)。 在监督学习中,我...
Deep Learning 就是训练非常庞大的神经网络结构(neural network(NN)), 因此懂得什么是 NN 是非常重要的。 NN 就是由很多的 neuron 叠加组合起来的结构网络。当前层的 neurons 到下一层neurons 可以看做是一种函数映射。其作用就是将输入参数经过特定逻辑处理映射到输出参数。这种映射关系可以是线性的(ex. linear ...

Log (logistic regression, cross entropy error) Squared loss (linear regression) Exponential loss (Boosting) 因为我们做的是分类,所以Log是首选哦。−ylog(y¯)−(1−y)log(1−y¯)视频里讲的很细,我简单来说一下原因,你可以看到log函数的图像,当等于y=1的时候,其实就是−log(y¯),这时...
