Anomaly detection refers to the task of finding unusual instances that stand out from the normal data. In several applications, these outliers or anomalous instances are of greater interest compared to the normal ones. Specifically in the case of industrial optical inspection and infrastructure asset ...
AutoEncoder是深度学习的一个重要内容,并且非常有意思,神经网络通过大量数据集,进行end-to-end的训练,不断提高其准确率,而AutoEncoder通过设计encode和decode过程使输入和输出越来越接近,是一种无监督学习过程,可以被应用于降维(dimensionality reduction)和异常值检测(anomaly detection),包含卷积层构筑的自编码器可被应用...
for i in range(len(results)): if results[i] == 1: print("Sample", i, "is an anomaly.") else: print("Sample", i, "is normal.") 这个示例代码使用了TensorFlow库来实现稀疏自编码器进行异常检测。首先,定义了稀疏自编码器的网络结构,包括输入层和隐藏层的神经元个数。然后,定义了稀疏自编码器...
First, we set up aTensorFlow estimator object(estimator) for SageMaker hosted training. The key parameters for the estimator include the following: Hyperparameters– The hyperparameters for training the model entry_point– The path to the local Python source file, ...
More specifically, autoencoders have been used on industry for anomaly detection on railways [14]. However, in this approach the authors obtain the different stages of the problem by dividing the timestamp of opening and closing the doors in 5 equal bins (using time as the divisor element)....
