This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The increased availability of time series data has led to a burgeoning interest in data-driven modeling and time series analysis. The ability to model temporal data can not only enable us to discover patterns inherent in a set of collected measurements, but also predict future trends. However, collected temporal measurements are oftentimes artifacted with noise, making it difficult to discern the actual signal. This presence of noise can greatly bias models, resulting in inaccurate forecasts with high uncertainty. In this thesis,I demonstrate how data-driven methods can be applied to a wide array of artifacted data while circumventing noise-induced bias.I first show the application of various data-driven methods and signal processing techniques on labeled time series data. Specifically, I apply supervised machine learning and signal processing techniques on corrupted electrocardiograms (ECGs) in order to classify pulse status in patients undergoing cardiac arrest. I then introduce a data-driven method that leverages statistical bagging and optimized Dynamic Mode Decomposition (optDMD) in order to produce accurate long-term forecasting and spatial and temporal uncertainty quantification for unlabeled, non-stationary time series. I then highlight the robustness of this method by applying it to corrupted flu transmission data in order to predict future flu trends as well as gain insight into temporal cycles of modes.

Download or read book A Data Driven Based Comparison Study of Statistical and Deep Learning Based Time Series Forecasting Methods for Infectious Disease Modeling and Financial Data written by Vinay Kumar Reddy Chimmula and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In regard to human history, it isn't that long since forecasting transitioned from the spiritual and mythical components into the scientific domain. In recent years, forecasting has become an integral part of the mathematical analysis. It has a wide range of significance in various domains and is critical in some life-saving applications. The crucial element in determining the suitable forecasting model is its accuracy. Most of the existing approaches are either based on the statistical or random analysis. One of the limitations of such models is the failure to capture the nonlinearities that are present in the data. Given the inadequacy of classical models in processing hidden non-linear sequences, deep learning models have been showing better results in time series forecasting applications. We addressed this issue by proposing a deep learning-based LSTM model to solve various time series problems. In order to justify our claims, the proposed LSTM models are tested on various datasets including retail, financial and epidemiological data. Forecasting results of different models show that statistical models outperformed deep learning models on small datasets. Meanwhile, deep learning models performed well on large nonstationary data sets. Deep learning-based time series forecasting models are being used in largescale real-world applications over the last few years. After winning the recent M4 competition, the popularity of Deep Learning based models is not only confirmed to academia but also being used for industrial applications. In addition to that, in this novel research, we modeled the current COVID-19 pandemic using deep learning-based time series modeling. This thesis aims at time series modeling and forecasting under different circumstances using statistical and deep learning approaches for various unexplored applications. We addressed the limitations of traditional time series forecasting procedures and proposed various deep learning architectures with multi-layer Recurrent Networks (RNN) and how they may be exploited for time series forecasting problems. The new abilities of neural networks in generating complex mapping functions, feature extraction tools and support for sequential are provided by Recurrent Neural Networks (RNN) and Long Short-Term Memory networks (LSTM). Finally, we outlined the underlying factors behind the success of Deep Learning (DL) methods and given some directions for future applications. keywords: Time Series Forecasting, Infectious.

Download or read book Bayesian Reinforcement Learning written by Mohammad Ghavamzadeh and published by . This book was released on 2015-11-18 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bayesian methods for machine learning have been widely investigated, yielding principled methods for incorporating prior information into inference algorithms. This monograph provides the reader with an in-depth review of the role of Bayesian methods for the reinforcement learning (RL) paradigm. The major incentives for incorporating Bayesian reasoning in RL are that it provides an elegant approach to action-selection (exploration/exploitation) as a function of the uncertainty in learning, and it provides a machinery to incorporate prior knowledge into the algorithms. Bayesian Reinforcement Learning: A Survey first discusses models and methods for Bayesian inference in the simple single-step Bandit model. It then reviews the extensive recent literature on Bayesian methods for model-based RL, where prior information can be expressed on the parameters of the Markov model. It also presents Bayesian methods for model-free RL, where priors are expressed over the value function or policy class. Bayesian Reinforcement Learning: A Survey is a comprehensive reference for students and researchers with an interest in Bayesian RL algorithms and their theoretical and empirical properties.

Available in PDF, EPUB and Kindle. Book excerpt: When you enter the world of time series analysis, you step into a labyrinth of numerical patterns, where each turn you take unveils another layer of complexity. Here, simple mathematical or statistical models struggle to keep pace. Reality is riddled with complex patterns in time series data, which, like cryptic pieces of a jigsaw puzzle, hold the key to unraveling insightful predictions. These complex patterns include non-linearity, non-stationarity, long memory or dependence, asymmetry, and stochasticity. But what creates these intricate patterns? Raghurami Reddy Etukuru, Ph.D., a distinguished and adaptable specialist in data science and artificial intelligence, delves into that question in this groundbreaking book, explaining that the factors are numerous and multifaceted, each adding their own measure of challenge. He doesn't just discuss problems but also addresses the forecasting of time series amidst intricate patterns. Take a deep dive deep into the world of numbers and patterns, so you can unravel complexities and leverage the power of artificial intelligence to enhance predictive capabilities. More than just a theoretical guide, this book is a practical companion in the often-turbulent journey of understanding and predicting complex time series data.

Download or read book Computational Approaches for Time Series Analysis and Prediction written by Yang Lan and published by . This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Time series data mining is one branch of data mining. Time series analysis and prediction have always played an important role in human activities and natural sciences. A Pseudo-Periodical time series has a complex structure, with fluctuations and frequencies of the times series changing over time. Currently, Pseudo-Periodicity of time series brings new properties and challenges to time series analysis and prediction. This thesis proposes two original computational approaches for time series analysis and prediction: Moving Average of nth-order Difference (MANoD) and Series Features Extraction (SFE). Based on data-driven methods, the two original approaches open new insights in time series analysis and prediction contributing with new feature detection techniques. The proposed algorithms can reveal hidden patterns based on the characteristics of time series, and they can be applied for predicting forthcoming events. This thesis also presents the evaluation results of proposed algorithms on various pseudo-periodical time series, and compares the predicting results with classical time series prediction methods. The results of the original approaches applied to real world and synthetic time series are very good and show that the contributions open promising research directions.
