Working with Time Series Data in MATLAB
 
53:29
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. About the Presenter: Abhaya is an Application Engineer at MathWorks Australia where he applies methods from the fields of mathematical and physical modelling, optimisation, signal processing, statistics and data analysis across a range of industries. Abhaya holds a Ph.D. and a B.E. (Software Engineering) both from the University of Sydney, Australia. In his research he focused on array signal processing for audio and acoustics and he designed, developed and built a dual concentric spherical microphone array for broadband sound field recording and beam forming.

fasster: Forecasting multiple seasonality with state switching
 
20:13
Forecasting time-series which contain multiple seasonal patterns requires flexible modelling approaches, and the need for continuously updating models emphasises the importance of fast model estimation. In response to shortcomings in current models, a new model is proposed which brings the desirable qualities of speed, flexibility and support for exogenous regressors into a state space model. This proposed model also introduces state switching, which captures groups of irregular multiple seasonality by switching between states. The functionality of the proposed model extends beyond forecasting, by allowing for model based time-series decomposition, imputation of missing values, and support for streaming data.This model is available as an R package (mitchelloharawild/fasster), which provides formula based model specification, and uses tidy data structures (tsibble) and APIs which will later become familiar in forecast's next iteration: tidyforecast.

Interpretable forecasting of financial time series with deep learning
 
01:44:35
Topic: Interpretable forecasting of financial time series with deep learning Abstract: In this talk I will present our deep learning approach to forecasting financial multivariate time series which indicate the market sentiment towards a financial asset. The interpretable deep neural network reveals the essential dependence between the time series’ variables, and in contrast to the widely used vector autoregressive model, the deep learning model dynamically adapts the dependence coefficients to the ever-changing market conditions. Thus, the proposed method permits the study of the inter-variable relationships which yields a better understanding of the asset’s future price movements and consequently increases the profitability of the asset’s trading activities. I will conclude the talk with dependence analysis and forecasting performance for financial assets from different sectors and with vastly different market capitalisation. Speaker: Ilija is a machine learning researcher building holistic models of unstructured data from multiple modalities. His diverse, six-year experience as a machine learning researcher includes projects on combining satellite images and census data for complex city models, utilizing movie metadata and watch statistics for recommender systems, and fusing image and text data representations for visual question answering. Currently Ilija is working on developing a unified model of financial data coming from multiple sources applied to portfolio optimization.

Time Series Forecasting Using Recurrent Neural Network and Vector Autoregressive Model: When and How
 
32:05
The General Data Protection Regulation (GDPR), which came into effect on May 25, 2018, establishes strict guidelines for managing personal and sensitive data, backed by stiff penalties. GDPR's requirements have forced some companies to shut down services and others to flee the EU market altogether. GDPR's goal to give consumers control over their data and, thus, increase consumer trust in the digital ecosystem is laudable. However, there is a growing feeling that GDPR has dampened innovation in machine learning & AI applied to personal and/or sensitive data. After all, ML & AI are hungry for rich, detailed data and sanitizing data to improve privacy typically involves redacting or fuzzing inputs, which multiple studies have shown can seriously affect model quality and predictive power. While this is technically true for some privacy-safe modeling techniques, it's not true in general. The root cause of the problem is two-fold. First, most data scientists have never learned how to produce great models with great privacy. Second, most companies lack the systems to make privacy-safe machine learning & AI easy. This talk will challenge the implicit assumption that more privacy means worse predictions. Using practical examples from production environments involving personal and sensitive data, the speakers will introduce a wide range of techniques--from simple hashing to advanced embeddings--for high-accuracy, privacy-safe model development. Key topics include pseudonymous ID generation, semantic scrubbing, structure-preserving data fuzzing, task-specific vs. task-independent sanitization and ensuring downstream privacy in multi-party collaborations. Special attention will be given to Spark-based production environments. Talk by Jeffrey Yau.

Case Study in Travel Business - Time Series Analysis with Seasonal Data - Cheuk Ting Ho
 
25:15
PyData Amsterdam 2018 For time series analysis, everyone's talking about ARIMA or Holt-Winters. But there's other models which could also break down a seasonal series into trend, seasonality and noise. We will use an open source Python library called Seasonal to analyse B2B worldwide travel data. Slides: https://www.slideshare.net/CheukTingHo/pydata-amsterdam-2018-time-series-analysis-with-seasonal-data-99093353 -- www.pydata.org PyData is an educational program of NumFOCUS, a 501(c)3 non-profit organization in the United States.

Rearchitecting a SQL Database for Time-Series Data | DataEngConf NYC '17
 
37:16
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.
