dl stands for "deep learning," a subset of machine learning that focuses on algorithms inspired by the structure and function of the brain, known as neural networks. It enables computers to learn from large amounts of data, improving their performance on tasks such as image recognition, natural language processing, and speech recognition. Deep learning models require significant computational power and large datasets to train effectively. They are widely used in various applications, including self-driving cars, virtual assistants, and medical diagnosis, making them a crucial technology in today's digital landscape.
