Program (detailed contents):
This course is dedicated to deep learning methods for processing complex data such as signals, images or sequential data (time series or textual data). It also covers methods for anomaly detection, especially in functional data.
* Convolutional neural networks: convolutional layer, pooling, dropout, architecture of convolutional networks (ResNet, Inception), transfer learning, applications to signal and image classification and object detection.
* Encoder-decoder, variational auto-encoder, generative adversarial networks.
* Functional decomposition on Spline, Fourier, wavelet or functional PCA bases: cubic splines, penalized least squares criterion, Fourier bases, wavelet bases, application in non-parametric regression, linear and non-linear estimators by thresholding, links with the LASSO method.
* Anomaly detection, Main algorithms: One Class SVM, Random Forest, Isolation Forest, Local Outlier Factor. Applications to anomaly detection for functional data.
* Recurrent networks (RNN, LSTM) for the analysis of sequential data.
