Uczenie maszynowe

Uczenie maszynowe (ang. machine learning) zajmuje się teorią i praktycznym zastosowaniem algorytmów analizujących dane — stanowi najciekawszą dziedzinę informatyki. Żyjemy w czasach przetwarzania olbrzymiej ilości informacji; za pomocą samouczących się algorytmów będących częścią uczenia maszynowego informacje te są przekształcane w rzeczywistą wiedzę. Dzięki licznym i potężnym bibliotekom o jawnym kodzie źródłowym, które powstały w ostatnich latach, prawdopodobnie teraz jest najlepszy czas, aby zainteresować się uczeniem maszynowym i nauczyć się wykorzystywać potężne algorytmy do wykrywania wzorców w przetwarzanych danych oraz prognozować przyszłe zdarzenia. Przykładami zastosowania Machine Learning są np. mechanizmy wyszukiwarek internetowych, GPS, autokorekta w edytorze tekstu czy boty w komunikatorach. Jedną z dziedzin uczenia maszynowego jest deep learning, podczas którego komputer uczy się procesów naturalnych dla ludzkiego mózgu (tworzy sieci neuronowe). Technologia ta jest wykorzystywana np. przy identyfikacji głosu i obrazów.

Time Series Analysis on AWS. Learn how to build forecasting models and detect anomalies in your time series data

Michaël Hoarau

Being a business analyst and data scientist, you have to use many algorithms and approaches to prepare, process, and build ML-based applications by leveraging time series data, but you face common problems, such as not knowing which algorithm to choose or how to combine and interpret them. Amazon Web Services (AWS) provides numerous services to help you build applications fueled by artificial intelligence (AI) capabilities. This book helps you get to grips with three AWS AI/ML-managed services to enable you to deliver your desired business outcomes.The book begins with Amazon Forecast, where you’ll discover how to use time series forecasting, leveraging sophisticated statistical and machine learning algorithms to deliver business outcomes accurately. You’ll then learn to use Amazon Lookout for Equipment to build multivariate time series anomaly detection models geared toward industrial equipment and understand how it provides valuable insights to reinforce teams focused on predictive maintenance and predictive quality use cases. In the last chapters, you’ll explore Amazon Lookout for Metrics, and automatically detect and diagnose outliers in your business and operational data.By the end of this AWS book, you’ll have understood how to use the three AWS AI services effectively to perform time series analysis.

Time Series with PyTorch. Modern Deep Learning Toolkit for Real-World Forecasting Challenges

Graeme Davidson, Lei Ma

Neural networks are powerful tools for time-series forecasting, but applying them effectively requires both practical experience and a clear understanding of architectures, training strategies, and evaluation methods. This book brings these ideas together in a structured and practical way.Starting with PyTorch fundamentals, you will build neural networks from scratch and progress through recurrent networks, attention mechanisms, and transformers before exploring forecasting architectures such as N-BEATS, N-HiTS, and the Temporal Fusion Transformer. Along the way, you will learn robust hyperparameter tuning, conformal prediction for uncertainty estimation, and reliable evaluation practices.Unlike most forecasting books, this text also explores topics often overlooked or treated separately, including transfer learning across collections of series, synthetic data generation with diffusion models, and self-supervised representation learning. Beyond forecasting, later chapters cover classification, clustering, anomaly detection, and embeddings for large-scale time-series modeling.Throughout, the focus is pragmatic: theory is reinforced through experimentation and implementation so you can apply these methods confidently to real-world time-series problems.
