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.

Time-Series Forecast in the Energy Sector with Automated Machine Learning Stefano Casasso, Data Scientist at Predictive Layer SwissAI Machine Learning Meetup 2018.10.15 1. What is Time Series Analysis? 2. What are the common mistakes in time series analysis? 3. How to treat features in time series analysis? 4. Application example from the energy sector Abstract: Time series forecasting using machine learning (ML) presents additional challenges compared to other "static" ML tasks. From data cleaning to feature engineering, from model building to model validation: in each of these steps the time component has to be handled with care in order to avoid overfitting and bias. In this presentation, all these tasks are discussed using "real world" examples taken from the energy sector, namely electricity consumption/production. Predictive Layer (PL) is a company based in Rolle (Switzerland) which has built its business model around times series forecasting. PL is currently active in the sector of energy, finance, retail, transport and supply chain optimization. http://www.predictivelayer.com Bio: Stefano Casasso studied experimental particle physics in Turin, Italy, where he obtained his Ph.D. with a thesis on the newly observed Higgs boson at the Large Hadron Collider at CERN, Geneva. He spent 3 more years at CERN as a research associate for the Imperial College, London analyzing the data of the CMS particle detector in search of production of so-called "supersymmetric particles". Since 2 years he turned into data science in the private sector. After a short period in Zürich, working in the IoT sector, he joined Predictive Layer where he is specializing in the analysis of time series data and predictive modeling. In particular, he is responsible for the projects in the energy sector, where he applies his skills to forecast energy demand, renewable energy production, and electricity price. https://www.linkedin.com/in/stefano-casasso/ ## Organizers ## SwissAI Machine Learning Meetup is one of the larges AI meetups in Switzerland, with regular meetings, great speakers invited from academia and industry and over 1200 members from Lake Geneva Area.

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.

It was originally proposed in 1978 by Sakoe and Chiba for speech recognition, and it has been used up to today for time series analysis. DTW is one of the most used measure of the similarity between two time series, and computes the optimal global alignment between two time series, exploiting temporal distortions between them.

Authors: Mohammad Shokoohi-Yekta, Yanping Chen, Bilson Campana, Bing Hu, Jesin Zakaria, Eamonn Keogh Abstract: The ability to make predictions about future events is at the heart of much of science; so, it is not surprising that prediction has been a topic of great interest in the data mining community for the last decade. Most of the previous work has attempted to predict the future based on the current value of a stream. However, for many problems the actual values are irrelevant, whereas the shape of the current time series pattern may foretell the future. The handful of research efforts that consider this variant of the problem have met with limited success. In particular, it is now understood that most of these efforts allow the discovery of spurious rules. We believe the reason why rule discovery in real-valued time series has failed thus far is because most efforts have more or less indiscriminately applied the ideas of symbolic stream rule discovery to real-valued rule discovery. In this work, we show why these ideas are not directly suitable for rule discovery in time series. Beyond our novel definitions/representations, which allow for meaningful and extendable specifications of rules, we further show novel algorithms that allow us to quickly discover high quality rules in very large datasets that accurately predict the occurrence of future events.

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.

"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.

PyData London 2016 This talk will present best-practices and most commonly used methods for dealing with irregular time series. Though we'd all like data to come at regular and reliable intervals, the reality is that most time series data doesn't come this way. Fortunately, there is a long-standing theoretical framework for knowing what does and doesn't make sense for corralling this irregular data. Irregular time series and how to whip them History of irregular time series Statisticians have long grappled with what to do in the case of missing data, and missing data in a time series is a special, but very common, case of the general problem of missing data. Luckily, irregular time series offer more information and more promising techniques than simple guesswork and rules of thumb. Your best options I'll discuss best-practices for irregular time series, emphasizing in particular early-stage decision making driven by data and the purpose of a particular analysis. I'll also highlight best-Python practices and state of the art frameworks that correspond to statistical best practices. In particular I'll cover the following topics: Visualizing irregular time series Drawing inferences from patterns of missing data Correlation techniques for irregular time series Causal analysis for irregular time series Slides available here: https://speakerdeck.com/aileenanielsen/irregular-time-series-and-how-to-whip-them

Any process that varies over time is a time-series process provided the interval is fixed. If you are talking about monthly data and one month is the interval between two time points, then you should have one value of the variable every month for it to be defined as a time-series process. Time-series data is a sequence of records collected from a process with equally spaced intervals in time. In simple terms, any metric that is measured over time is a time-series process, given that the time interval is the same between any two consecutive points. In the following text, you will consider some time-series plots as examples. The session is an initiative by Shashi Online Classes and it is conducted taken by Ankit Shaw.

A Framework for Periodic Outlier Pattern Detection in Time-Series Sequences: Abstract: Periodic pattern detection in time-ordered sequences is an important data mining task, which discovers in the time series all patterns that exhibit temporal regularities. Periodic pattern mining has a large number of applications in real life; it helps understanding the regular trend of the data along time, and enables the forecast and prediction of future events. An interesting related and vital problem that has not received enough attention is to discover outlier periodic patterns in a time series.Outlier patterns are defined as those which are different from the rest of the patterns; outliers are not noise. While noise does not belong to the data and it is mostly eliminated by preprocessing, outliers are actual instances in the data but have exceptional characteristics compared with the majority of the other instances. Outliers are unusual patterns that rarely occur, and, thus, have lesser support (frequency of appearance) in the data. Outlier patterns may hint toward discrepancy in the data such as fraudulent transactions, network intrusion, change in customer behavior, recession in the economy, epidemic and disease biomarkers, severe weather conditions like tornados, etc. We argue that detecting the periodicity of outlier patterns might be more important in many sequences than the periodicity of regular, more frequent patterns. In this paper, we present a robust and time efficient suffix tree-based algorithm capable of detecting the periodicity of outlier patterns in a time series by giving more significance to less frequent yet periodic patterns. Several experiments have been conducted using both real and synthetic data; all aspects of the proposed approach are comparedwith the existing algorithm InfoMiner; the reported results demonstrate the effectiveness and applicability of the proposed approach.

What is DATA STREAM MINING? What does V mean? DATA STREAM MINING meaning - DATA STREAM MINING definition - DATA STREAM MINING explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ Data Stream Mining is the process of extracting knowledge structures from continuous, rapid data records. A data stream is an ordered sequence of instances that in many applications of data stream mining can be read only once or a small number of times using limited computing and storage capabilities. In many data stream mining applications, the goal is to predict the class or value of new instances in the data stream given some knowledge about the class membership or values of previous instances in the data stream. Machine learning techniques can be used to learn this prediction task from labeled examples in an automated fashion. Often, concepts from the field of incremental learning are applied to cope with structural changes, on-line learning and real-time demands. In many applications, especially operating within non-stationary environments, the distribution underlying the instances or the rules underlying their labeling may change over time, i.e. the goal of the prediction, the class to be predicted or the target value to be predicted, may change over time. This problem is referred to as concept drift. Examples of data streams include computer network traffic, phone conversations, ATM transactions, web searches, and sensor data. Data stream mining can be considered a subfield of data mining, machine learning, and knowledge discovery.
