Last Updated on August 5, 2019 Machine learning and deep learning methods are often reported to be the key solution to all predictive modeling problems. An important recent study evaluated and compared the performance of many classical and modern machine learning and deep learning methods on a large and diverse set of more than 1,000 univariate time series forecasting problems. The results of this study suggest that simple classical methods, such as linear methods and exponential smoothing, outperform complex and […]

Last Updated on August 5, 2019 Time series forecasting with LSTMs directly has shown little success. This is surprising as neural networks are known to be able to learn complex non-linear relationships and the LSTM is perhaps the most successful type of recurrent neural network that is capable of directly supporting multivariate sequence prediction problems. A recent study performed at Uber AI Labs demonstrates how both the automatic feature learning capabilities of LSTMs and their ability to handle input sequences […]

Last Updated on August 28, 2020 Time series data must be transformed into a structure of samples with input and output components before it can be used to fit a supervised learning model. This can be challenging if you have to perform this transformation manually. The Keras deep learning library provides the TimeseriesGenerator to automatically transform both univariate and multivariate time series data into samples, ready to train deep learning models. In this tutorial, you will discover how to use […]

Last Updated on August 28, 2020 Multilayer Perceptrons, or MLPs for short, can be applied to time series forecasting. A challenge with using MLPs for time series forecasting is in the preparation of the data. Specifically, lag observations must be flattened into feature vectors. In this tutorial, you will discover how to develop a suite of MLP models for a range of standard time series forecasting problems. The objective of this tutorial is to provide standalone examples of each model […]

Last Updated on August 28, 2020 Grid searching is generally not an operation that we can perform with deep learning methods. This is because deep learning methods often require large amounts of data and large models, together resulting in models that take hours, days, or weeks to train. In those cases where the datasets are smaller, such as univariate time series, it may be possible to use a grid search to tune the hyperparameters of a deep learning model. In […]
