Practical Time Series Analysis Coursera

@machinelearnbot

About this course: Welcome to Practical Time Series Analysis! Many of us are "accidental" data analysts. We trained in the sciences, business, or engineering and then found ourselves confronted with data for which we have no formal analytic training. This course is designed for people with some technical competencies who would like more than a "cookbook" approach, but who still need to concentrate on the routine sorts of presentation and analysis that deepen the understanding of our professional topics. In practical Time Series Analysis we look at data sets that represent sequential information, such as stock prices, annual rainfall, sunspot activity, the price of agricultural products, and more.


Feature Engineering for Time Series Analysis โ€“ ODSC East 2018

Forecasting is a core part of time series analysis as it tries tries to predict the value of the analysed signal. Forecasting is one of the hardest problems in predictive analytics because it's not always obvious what attributes can explain the future values of the signal and because you often will have less data than you would like to have, for example, if you have monthly data over a 4 year period you will basically have 48 data points. As time series analysis data is temporal, you will often have one data points per timestamp. The motto, "the more data the better," is true only up to a certain point, particularly when running a time series analysis. Adding more data can actually negatively impact your model.

You will learn how to hack and analyze data in a given period or time series to make future predictions. You will learn how to use machine learning algorithms to make predictions of your time series model.


Structured low-rank matrix completion for forecasting in time series analysis

arXiv.org Machine Learning

In this paper we consider the low-rank matrix completion problem with specific application to forecasting in time series analysis. Briefly, the low-rank matrix completion problem is the problem of imputing missing values of a matrix under a rank constraint. We consider a matrix completion problem for Hankel matrices and a convex relaxation based on the nuclear norm. Based on new theoretical results and a number of numerical and real examples, we investigate the cases when the proposed approach can work. Our results highlight the importance of choosing a proper weighting scheme for the known observations.


Time Series Analysis in Python: An Introduction โ€“ Towards Data Science

#artificialintelligence

Time series are one of the most common data types encountered in daily life. Financial prices, weather, home energy usage, and even weight are all examples of data that can be collected at regular intervals. Almost every data scientist will encounter time series in their daily work and learning how to model them is an important skill in the data science toolbox. One powerful yet simple method for analyzing and predicting periodic data is the additive model. The idea is straightforward: represent a time-series as a combination of patterns at different scales such as daily, weekly, seasonally, and yearly, along with an overall trend.


Time Series Analysis and Forecasting: Novel Business Perspectives

@machinelearnbot

Time series forecasting is hardly a new problem in data science and statistics. The term is self-explanatory and has been on business analysts' agenda for decades now: The very first practices of time series analysis and forecasting trace back to the early 1920s.



[D] Potential Research idea: regional CNN for financial time-series analysis โ€ข r/MachineLearning

@machinelearnbot

Recently, I've been trying to figure out new and interesting ways to combine deep learning and finance (totally not for my master thesis or anything like that). I've read that CNN and their variations could be applied to predict financial things like stock prices to somewhat decent extent.
