人工智能(Artificial Intelligence, AI)领域经历了从符号主义(Symbolism)到机器学习(Machine Learning)的变革。近年来,深度学习(Deep Learning)和强化学习(Reinforcement Learning)的结合为AI带来了性的突破。这种结合不仅提升了AI系统的表现,还扩展了其应用范围,影响了从图像识别到自然语言处理等多个领域。 1. 深度学习的...
Deep learning本身算是machine learning的一个分支,简单可以理解为neural network的发展。大约二三十年前,neural network曾经是ML领域特别火热的一个方向,但是后来确慢慢淡出了,原因包括以下几个方面: 1)比较容易过拟合,参数比较难tune,而且需要不少trick; 2)训练速度比较慢,在层次比较少(小于等于3)的情况下效果并不...
AI is the overarching system. Machine learning is a subset of AI. Deep learning is a subfield of machine learning, and neural networks make up the backbone of deep learning algorithms. It’s the number of node layers, or depth, of neural networks that distinguishes a single neural network f...
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...

深度学习 Deep Learning:超过三层的神经网络。其中最核心的部分是根据loss调整w和b,具体可以用的算法例如梯度下降法gradient descent,这是对loss函数中的w跟b分别求偏导,使w跟b沿着loss函数下降最快的方向进行迭代。 w_{n+1}=w_n-\alpha\cdot\frac{\partial L}{\partial w_n} ...
Before exploring how to train a deep neural network (DNN) machine learning model, let's consider what we're trying to achieve. Machine learning is concerned with predicting alabelbased on somefeaturesof a particular observation. In simple terms, a machine learning model is a function that ca...
