第一周:深度学习的实践层面(Practical aspects of Deep Learning) 1.1 训练,验证,测试集(Train / Dev / Test sets) 1)应用型机器学习是一个高度迭代的过程. 2)划分 3)注意 问题系列之一 1.2 偏差,方差(Bias /Variance) 1)区别 2)判断 3)注意 1.3 机器学习基础(Basic Recipe for Machine Learning) 1)流...
Deep Learning的优势不明显,这也是Deep Learning的模型在图像,声音等领域应用效果好的原因,因为这些领域原始特征数据基本含义是一致的,原始特征经过多层抽象后的高层特征是容易理解的,比如,从像素,到边缘,到形状,到类别特征,到物体的概貌,这种逐层抽象的“深度”特征抽象是可以理解,也就是可以“人工地”去设计这种深层...

Review training samples Manage image chips When the image chips are created, they are available for the deep learning training process in the Train model step. If the trained model does not meet the expectations for the analysis, this substep can be revisited. You can modify or collect addition...
Hence, if there are high-quality data for supervised learning, it is possible to classify the driver’s emotional state with only the DNN model through the deep learning training process. The DNN model consists of N and maximum M units of hidden layers. We set the number of final layer ...
Inference is where capabilities learned during deep learning training are put to work. Inference can’t happen without training. Makes sense. That’s how we gain and use our own knowledge for the most part. And just as we don’t haul around all our teachers, a few overloaded bookshelves an...
其先是通过公开代码与技术报告揭示前沿大模型关键技术细节,随后启动“开源周”进一步开源了专门为Hopper 高性能 AI 芯片设计的先进技术 FlashMLA(https://github.com/deepseek-ai/FlashMLA)、 用于 MoE 模型训练和推理的 EP 通信库 DeepEP(https://github.com/deepseek-ai/DeepEP)以及 DualPipe、EPLB、profile-...
因此要做的就是用梯度下降法,使这里的损失最小化。 在有Softmax 输出层时如何实现梯度下降法,关键方程是这个表达式dz[l]=^y−y𝑑𝑧[𝑙]=𝑦^−y具体推导: softmax交叉熵损失函数求导 3.10 深度学习框架(Deep Learning frameworks) 3.11 TensorFlow tensorflow 基础使用,教程网上很多,自查。
无监督学习近年来很热,先后应用于computer vision, audio classification和 NLP等问题,通过机器进行无监督学习feature得到的结果,其accuracy大多明显优于其他方法进行training。本文将主要针对Andrew的unsupervised learning,结合他的视频:unsupervised feature learning by Andrew Ng做出导论性讲解。
