Study Notes
Vectors and Matrices
- A vector is a mathematical object used to represent quantities with both magnitude and direction.
Mathematical Notation
- The symbol ∑ (sigma) represents the summation of a sequence of numbers in mathematics.
Matrix Dimensions
- 'n x m' denotes the dimensions of a matrix, where 'n' is the number of rows and 'm' is the number of columns.
Probability
- Bayesian probability is based on personal beliefs and subjective probabilities, using prior knowledge to update probabilities as new data arises.
- Frequentist probability is based on the frequency of occurrence of events, using long-run relative frequencies to estimate probabilities.
Matrices
- A square matrix is a matrix with the same number of rows and columns (n x n).
