That being said, let us run a quick dimensional analysis to estimate the complexity of our problem. Oftentimes the nature of a problem is determined by the data itself in our case, the way one chooses to process and classify a time series depends highly on the length and statistics of the data. After all, training and tuning a neural network can be very time-consuming so it is always a good practice to test the performance of other ML models and then seek for any potential shortcomings. It is always important to remind ourselves that DL is nothing but a set of tools for solving problems, and although DL can be very powerful, that doesn’t mean that we should blindly apply DL techniques to every single problem out there. A dataset S is a set of n such training instances: S=. More formally, let (X, y) be a training instance with T observations (X¹, … ,Xᵀ)≡ X (the time series) and a discrete class variable y which takes k possible values (the labels). the historical data of a financial asset), it outputs labels (e.g. To be more concrete, we are interested in training an ML model which when fed with a series of data points indexed in time order (e.g. TSC is the area of ML interested in learning how to assign labels to time series. Machine Learning for Time Series Classification In this article, I discuss the (very) recent discoveries on Time Series Classification (TSC) with Deep Learning, by following a series of publications from the authors of. It is therefore of great interest to understand the role and potentials of Machine Learning (ML) in this rising field. In the last couple of years, several key players in cloud services, such as Apache Kafka and Apache Spark, have released new products for processing time series data. ![]() Time series data have always been of major interest to financial services, and now with the rise of real-time applications, other areas such as retail and programmatic advertising are turning their attention to time-series data driven applications.
