Practical Time Series Analysis. Master Time Series Data Processing, Visualization, and Modeling using Python

Avishek Pal, PKS Prakash

Time Series Analysis allows us to analyze data which is generated over a period of time and has sequential interdependencies between the observations. This book describes special mathematical tricks and techniques which are geared towards exploring the internal structures of time series data and generating powerful descriptive and predictive insights. Also, the book is full of real-life examples of time series and their analyses using cutting-edge solutions developed in Python. The book starts with descriptive analysis to create insightful visualizations of internal structures such as trend, seasonality, and autocorrelation. Next, the statistical methods of dealing with autocorrelation and non-stationary time series are described. This is followed by exponential smoothing to produce meaningful insights from noisy time series data. At this point, we shift focus towards predictive analysis and introduce autoregressive models such as ARMA and ARIMA for time series forecasting. Later, powerful deep learning methods are presented, to develop accurate forecasting models for complex time series, and under the availability of little domain knowledge. All the topics are illustrated with real-life problem scenarios and their solutions by best-practice implementations in Python.The book concludes with the Appendix, with a brief discussion of programming and solving data science problems using Python.

Praktyczne uczenie nienadzorowane przy użyciu języka Python

Ankur A. Patel

Wielu ekspertów branżowych uważa uczenie nienadzorowane za kolejną granicę w dziedzinie sztucznej inteligencji, która może stanowić klucz do pełnej sztucznej inteligencji. Ponieważ większość danych na świecie jest nieoznakowana, nie można do nich zastosować konwencjonalnego uczenia nadzorowanego. Z kolei uczenie nienadzorowane może być stosowane wobec nieoznakowanych zbiorów danych w celu odkrycia istotnych wzorców ukrytych głęboko w tych danych, które dla człowieka mogą być niemal niemożliwe do odkrycia. Autor Ankur Patel pokazuje, jak stosować uczenie nienadzorowane przy wykorzystaniu dwóch prostych platform dla języka Python: Scikit-learn oraz TensorFlow (wraz z Keras). Dzięki dołączonemu kodowi i praktycznym przykładom analitycy danych będą mogli identyfikować trudne do znalezienia wzorce w danych i odkrywać dogłębne zależności biznesowe, wykrywać anomalie, przeprowadzać automatyczną selekcję zmiennych i generować syntetyczne zbiory danych. Wystarczy znajomość programowania i nieco doświadczenia w uczeniu maszynowym, aby zająć się: Porównywaniem mocnych i słabych stron różnych podejść do uczenia maszynowego: uczenia nadzorowanego, nienadzorowanego i wzmacnianego. Przygotowywaniem i zarządzaniem projektami uczenia maszynowego. Budowaniem systemu wykrywania anomalii w celu wychwycenia oszustwa dotyczącego kard kredytowych. Rozdzielaniem użytkowników na wydzielone i jednorodne grupy. Przeprowadzaniem uczenia pół-nadzorowanego. Opracowywaniem systemów polecania filmów z użyciem ograniczonych automatów Boltzmanna. Generowaniem syntetycznych obrazów przy użyciu generujących sieci antagonistycznych. Badacze, inżynierowie i studenci docenią tę książkę pełną praktycznych technik uczenia nienadzorowanego, napisaną prostym językiem z nieskomplikowanymi przykładami w języku Python, które można szybko i skutecznie implementować. Sarah Nagy Główny analityk danych w firmie Edison Ankur A. Patel jest wiceprezesem ds. informatyki analitycznej w firmie 7Park Data, wspieranej przez firmę inwestycyjną Vista Equity Partners. W firmie 7Park Data, Ankur i jego zespół analizy danych wykorzystują dane alternatywne do opracowywania produktów związanych z danymi dla funduszy hedgingowych i korporacji oraz rozwijają usługi uczenia maszynowego dla klientów firmowych.
