Questions & Answers

Q: What is the definition of artificial intelligence?

Artificial intelligence refers to a machine's ability to perform cognitive functions associated with human minds, including learning, problem-solving, and decision-making.

Q: How does machine learning work?

Machine learning involves using data points, computing power, and mathematical formulas to optimize models. Through iterations, the model can approximate patterns and make predictions based on the input data.

Q: What is deep learning and how is it different from machine learning?

Deep learning is a subset of machine learning that focuses on neural networks. Neural networks are inspired by the human brain and have hidden layers, making them "deep." Deep learning utilizes these complex networks to process data and improve AI capabilities.

Q: What are embeddings in natural language processing (NLP)?

Embeddings refer to the process of transforming numbers into representations of natural language or vice versa. It allows computers, which work with numbers, to process and understand human languages.
