- 4. Gradient descent Gradient descent is a first-order iterative optimization algorithm for finding the minimum of a function.
- 6. Gradient descent Gradient descent is a popular method in the field of machine learning because part of the process of machine learning is to find the highest accuracy, or to minimize the error rate, given a set of training data. Gradient descent is used to find the minimum error by minimizing a "cost" function.
- 7. Neuron The artificial neuron receives one or more inputs (representing dendrites) and sums them to produce an output (or activation) (representing a neuron's axon). Usually the sums of each node are weighted, and the sum is passed through a non-linear function known as an activation function.

- 15. Deep Learning Deep learning (also known as deep structured learning or hierarchical learning) is the application of artificial neural networks (ANNs) to learning tasks that contain more than one hidden layer. Deep learning is part of a broader family of machine learning methods based on learning data representations, as opposed to task-specific algorithms. Learning can be supervised, partially supervised or unsupervised.
- 16. AI vs ML vs DL Artificial Intelligence: Computer system(s) that mimics and/or replicates human intelligence. Machine Learning: Allows computers to learn on their own. Deep Learning: Algorithms attempting to model high level abstractions in data to determine a high level meaning.
