Description
This book aims to provide an introduction to machine learning and deep learning concepts and algorithms applied to a diverse set of behavior analysis problems.
The book covers topics and practical aspects within the entire data analysis pipeline—from data collection, visualization, preprocessing, and encoding to model training and evaluation. No prior knowledge in machine learning is assumed. The book covers How To:
- Build supervised machine learning models to predict indoor locations based on Wi-Fi signals, recognize physical activities from smartphone sensors and 3D skeleton data, detect hand gestures from accelerometer signals, and much more.
- Apply some of the most common techniques to explore, visualize, encode, and preprocess behavioral data.
- Use unsupervised learning algorithms to discover criminal behavioral patterns.
- Program your own ensemble learning methods and use multi-view stacking to fuse signals from heterogeneous data sources.
- Encode your data using different representations, such as feature vectors, time series, images, bags of words, graphs, and so on.
- Train deep learning models with Keras and TensorFlow, including neural networks to classify muscle activity from electromyography signals and convolutional neural networks to detect smiles in images.
- Evaluate the performance of your models in traditional and multi-user settings.
- Train anomaly detection models such as Isolation Forests and autoencoders to detect abnormal fish trajectories.
- And much more!
