A field-programmable gate array (FPGA) is an integrated circuit that can be programmed to perform complex digital logic functions. Unlike microcontrollers, which have fixed functionality, FPGAs can be reconfigured to perform different tasks. They are used in applications such as digital signal processing, image processing, and networking. Read on Machine learning is a field of study that focuses on the development of algorithms that can learn from data and make predictions or decisions based on that data. Machine learning is used in many applications, such as image and speech recognition, natural language processing, and autonomous vehicles. Popular machine learning frameworks include TensorFlow, PyTorch, and scikit-learn.
