Introducing Time Series Data
(Index: https://www.stat.auckland.ac.nz/~wild/wildaboutstatistics/ ) We’ll learn to plot series of data against time and use techniques that ‘pull apart’ our plots to help identify patterns. After you’ve watched this video, you should be able to answer these questions •What is time-series data? •Why are people interested in time-series data? •What is quarterly data? •Why do people plot time-series data with points joined up by lines instead of using normal scatterplots? •What, besides trends, is another form of pattern that is very common in time-series data

Machine Learning for Time Series Data in Python | SciPy 2016 | Brett Naul
The analysis of time series data is a fundamental part of many scientific disciplines, but there are few resources meant to help domain scientists to easily explore time course datasets: traditional statistical models of time series are often too rigid to explain complex time domain behavior, while popular machine learning packages deal almost exclusively with 'fixed-width' datasets containing a uniform number of features. Cesium is a time series analysis framework, consisting of a Python library as well as a web front-end interface, that allows researchers to apply modern machine learning techniques to time series data in a way that is simple, easily reproducible, and extensible.

Data Mining and Prediction Modelling in the Dairy Industry Using Time Series and Sliding Windows
"WHY - As a major livestock producer, the European Union is directly affected by the global need for more sustainable food production. Climate change will undoubtedly impact on farm animal production but the health and welfare of livestock is also of increasing public concern. Due to rapid development of precision livestock farming technologies and availability of high-throughput from milk sensors, large-scale massive data has become available on research farms. The preferred matrix to measure the biomarkers is milk, as it is more accessible than blood and allows low-cost, automated repeat sampling using ‘in-line’ sampling and analytical technologies. WHAT - Certain biomarkers in milk such as N-glycan structures (BM-1), metabolites (BM-2) or mid-infra-red spectra (BM-3) can serve as biomarkers to predict production efficiency and disease. Data mining and machine learning can unlock insights around such biomarkers. As more of the aforementioned types of datasets become available over the near future, scalable data mining and prediction pipelines applied to animals science are needed. TAKEAWAYS -In this session you will learn: The methodology for ranking multiple biomarkers according to their predictive power; Data processing and statistical modelling performed using Spark v2.1.1 with scala API; Infrastructure, configuration, and implementation of the data pipeline using sliding windows with Apache Spark’s MLlib Visualization of of datasets via ElasticSearch-Kibana.

Working with Time Series Data in MATLAB
See what's new in the latest release of MATLAB and Simulink: https://goo.gl/3MdQK1 Download a trial: https://goo.gl/PSa78r A key challenge with the growing volume of measured data in the energy sector is the preparation of the data for analysis. This challenge comes from data being stored in multiple locations, in multiple formats, and with multiple sampling rates. This presentation considers the collection of time-series data sets from multiple sources including Excel files, SQL databases, and data historians. Techniques for preprocessing the data sets are shown, including synchronizing the data sets to a common time reference, assessing data quality, and dealing with bad data. We then show how subsets of the data can be extracted to simplify further analysis.

Toeplitz Inverse Covariance-Based Clustering of Multivariate Time Series Data
Toeplitz Inverse Covariance-Based Clustering of Multivariate Time Series Data David Hallac (Stanford University) Sagar Vare (Stanford University) Stephen Boyd (Stanford University) Jure Leskovec (Stanford University) Subsequence clustering of multivariate time series is a useful tool for discovering repeated patterns in temporal data. Once these patterns have been discovered, seemingly complicated datasets can be interpreted as a temporal sequence of only a small number of states, or clusters. For example, raw sensor data from a fitness-tracking application can be expressed as a timeline of a select few actions (i.e., walking, sitting, running). However, discovering these patterns is challenging because it requires simultaneous segmentation and clustering of the time series. Furthermore, interpreting the resulting clusters is difficult, especially when the data is high-dimensional. Here we propose a new method of model-based clustering, which we call Toeplitz Inverse Covariance-based Clustering (TICC). Each cluster in the TICC method is defined by a correlation network, or Markov random field (MRF), characterizing the interdependencies between different observations in a typical subsequence of that cluster. Based on this graphical representation, TICC simultaneously segments and clusters the time series data. We solve the TICC problem through an expectation maximization (EM) algorithm. We derive closed-form solutions to efficiently solve both the E and M-steps in a scalable way, through dynamic programming and the alternating direction method of multipliers (ADMM), respectively. We validate our approach by comparing TICC to several state-of-the-art baselines in a series of synthetic experiments, and we then demonstrate on an automobile sensor dataset how TICC can be used to learn interpretable clusters in real-world scenarios.

#bbuzz 2015: Andrew Clegg - Signatures, patterns and trends: Timeseries data mining at Etsy
Find more information here: http://berlinbuzzwords.de/session/signatures-patterns-and-trends-timeseries-data-mining-etsy Etsy loves metrics. Everything that happens in our data centres gets recorded, graphed and stored. But with over a million metrics flowing in constantly, it’s hard for any team to keep on top of all that information. Graphing everything doesn’t scale, and traditional alerting methods based on thresholds become very prone to false positives. That’s why we started Kale, an open-source software suite for pattern mining and anomaly detection in operational data streams. These are big topics with decades of research, but many of the methods in the literature are ineffective on terabytes of noisy data with unusual statistical characteristics, and techniques that require extensive manual analysis are unsuitable when your ops teams have service levels to maintain. In this talk I’ll briefly cover the main challenges that traditional statistical methods face in this environment, and introduce some pragmatic alternatives that scale well and are easy to implement (and automate) on Elasticsearch and similar platforms. I’ll talk about the stumbling blocks we encountered with the first release of Kale, and the resulting architectural changes coming in version 2.0. And I’ll go into a little technical detail on the algorithms we use for fingerprinting and searching metrics, and detecting different kinds of unusual activity. These techniques have potential applications in clustering, outlier detection, similarity search and supervised learning, and they are not limited to the data centre but can be applied to any high-volume timeseries data. Kale version 1 is described here: https://codeascraft.com/2013/06/11/introducing-kale/ Version 2 has the same goals but a very different architecture and suite of tools. Come along if you'd like to learn more.
Rearchitecting a SQL Database for Time-Series Data | DataEngConf NYC '17
Don’t miss the next DataEngConf in Barcelona: https://dataeng.co/2O0ZUq7 ABOUT THE TALK: Today everything is instrumented, generating more and more time-series data streams that need to be monitored and analyzed. When it comes to storing this data, many developers start with some well-trusted system like PostgreSQL. But when their data hits a certain scale, they often give up its query power and ecosystem by migrating to some NoSQL or other "modern" time-series architecture. In this talk, I describe why this perceived trade-off isn't necessary, and how we've built an efficient, scalable time-series database engineered up from PostgreSQL. In particular, the nature of time-series workloads one finds in devops, monitoring, IoT, finance, and elsewhere -- inserting new data about recent events -- presents very different demands than general transactional (OLTP) workloads. We've architected our time-series database to take advantage of and embrace these differences. The system architecture automatically partitions data across both time and space, even though it exposes the illusion of a single continuous table -- a hypertable -- across all of your data spread across one or many servers. Its distributed query optimizations both hide the fact that users are interacting with many "chunks" of data, which are right-sized by volume and time constraints, and minimize which and how chunks are accessed to answer queries. In fact, the database supports "full SQL" against this hypertable (e.g., secondary indexes, rich query predicates and group bys, aggregations, windowing functions, upserts, CTEs, JOINs). Through performance benchmarks, I show how the database scales much better than PostgreSQL, even on a single node. In particular, it avoids the "performance cliff" that vanilla PostgreSQL experiences at 10s of millions of rows, while maintaining robust performance past 100B rows. The database is implemented as a PostgreSQL extension, released under the Apache 2 license. ABOUT THE SPEAKER: Michael J. Freedman is a Professor in the Computer Science Department at Princeton University, as well as the co-founder and CTO of Timescale, building an open-source database that scales out SQL for time-series data. His work broadly focuses on distributed systems, networking, and security, and has led to commercial products and deployed systems reaching millions of users daily. Honors include a Presidential Early Career Award (PECASE), SIGCOMM Test of Time Award, Sloan Fellowship, DARPA CSSG membership, and multiple award publications.

On Thursday, March 19, 2015, Oliver Kramer, a juniorprofessor for computational intelligence at the University of Oldenburg in Germany and an ICSI alumnus, gave a talk about his work on data mining and green energy. Dr. Kramer's full abstract and bio are available at https://www.icsi.berkeley.edu/icsi/events/2015/03/kramer-data-mining-framework Abstract: Wind energy is playing an increasingly important part for ecologically friendly power supply. The fast growing infrastructure of wind turbines can be seen as a large sensor system that screens the wind energy at a high temporal and spatial resolution. The resulting databases consist of huge amounts of wind energy time series data that can be used for prediction, controlling, and planning purposes. In this talk, I describe WindML, a Python-based framework for wind energy related machine learning approaches.

Dafne van Kuppevelt | Deep learning for time series made easy
PyData Amsterdam 2017 Deep learning is a state of the art method for many tasks, such as image classification and object detection. For researchers that have time series data, but are not an expert on deep learning, the barrier can be high to start using deep learning. We developed mcfly, an open source python library, to help machine learning novices explore the value of deep learning for time series data. In this talk, we will explore how machine learning novices can be aided in the use of deep learning for time series classification. In a variety of scientific fields researchers face the challenge of time series classification. For example, to classify activity types from wrist-worn accelerometer data or to classify epilepsy from electroencephalogram (EEG) data. For researchers who are new to the field of deep learning, the barrier can be high to start using deep learning. In contrast to computer vision use cases, where there are tools such as caffe that provide pre-defined models to apply on new data, it takes some knowledge to choose an architecture and hyperparameters for the model when working with time series data. We developed mcfly, an open source python library to make time series classification with deep learning easy. It is a wrapper around Keras, a popular python library for deep learning. Mcfly provides a set of suitable architectures to start with, and performs a search over possible hyper-parameters to propose a most suitable model for the classification task provided. We will demonstrate mcfly with excerpts from (multi-channel) time series data from movement sensors that are associated with a class label, namely activity type (sleeping, walking, climbing stairs). In our example, mcfly will be used to train a deep learning model to label new data.
