<human>:  Describe the various technologies that use artificial intelligence.
<bot>: Artificial intelligence (AI) technologies include machine learning, natural language processing (NLP), computer vision, facial recognition, robotic processes automation (RPA), neural networks and deep learning. Machine learning is used in a variety of applications such as predictive analytics, recommendation systems, image recognition and autonomous systems. Natural language processing (NLP) is used to handle voice recognition, text analysis and audio and video analysis. Computer vision is used for tasks such as object identification, facial recognition, and autonomous navigation. Facial recognition is being used for facial recognition in security, video surveillance, and access control. Robotic processes automation (RPA) is used for automating repetitive tasks, freeing up manual labor and eliminating errors. Neural networks and deep learning allows machines to process data in complex ways and identify patterns over a large dataset.
