Vector

In data science, a vector is a one-dimensional array or list of numbers that represents a point in space. Vectors are commonly used to represent data in machine learning and statistical analysis. Each element in a vector represents a feature or attribute of the data point. Vectors can be manipulated using mathematical operations such as addition, subtraction, and multiplication. In machine learning, vectors are often used to represent input data for algorithms such as neural networks and support vector machines. They can also be used to represent the weights and biases of these algorithms. Vectors can be transformed using techniques such as normalization and dimensionality reduction to improve the performance of machine learning models.
