Normal Distribution
Definition of Normal Distribution A normal distribution is a type of bell-shaped distribution in which the majority of the data falls around the mean. This distribution is often used in statistics to model real-world data.
Naive Bayes Classifier
Definition of Naive Bayes Classifier A naive Bayes classifier is a machine learning algorithm that relies on the assumption that the features of a given object are independent of each other. This algorithm is often used for text classification tasks, such as sorting email into spam and non-spam folders.
N-gram
Definition of N-gram An n-gram is a contiguous sequence of n items from a given text or speech. N-grams are used to study linguistic patterns and to generate text samples.
Moving Average
Definition of Moving Average A moving average (MA) is a statistical measure that calculates the average value of a given set of data points over a designated amount of time. The MA is typically used to smooth out irregularities or fluctuations in the data and to help identify trends. The most common type of MA…
Monte Carlo method
Definition of Monte Carlo method The Monte Carlo method is a mathematical technique used to calculate the probability of an event by simulating many possible outcomes. How is the Monte Carlo method used? The Monte Carlo method is a numerical approach in which problems are solved by performing random sampling. It is used to solve…
Model
Definition of Model A model is a representation of something in order to understand it or predict its behavior. In machine learning, a model is a mathematical function that is used to predict the value of a target variable, given a set of input variables. How is a Model used? A Model is a mathematical…
Mean Squared Error
Definition of Mean Squared Error Mean Squared Error is a statistic used to measure the accuracy of predictions made by a machine learning model. It is calculated by taking the sum of the squared differences between the predicted values and the actual values for each data point, and dividing by the number of data points….
Mean Absolute Error
Definition of Mean Absolute Error Mean Absolute Error (MAE) is a measure of the accuracy of predictions made by a model. It is computed by taking the average of the absolute differences between the predicted values and the actual values for each observation. How is Mean Absolute Error used? Mean Absolute Error (MAE) is a…
MATLAB
Definition of MATLAB MATLAB is a software suite for high-performance numerical computation, visualization, and programming. It integrates mathematical computing, simulation, and graphical output into a single software environment. MATLAB is used extensively in engineering and scientific fields. How is MATLAB used? MATLAB is a high-level programming language developed by MathWorks for numerical computing and data…
Markov Chain
Definition of Markov Chain A Markov chain is a mathematical model for sequences of random events, where the probability of any event depends only on the immediately preceding event. How is Markov Chain used? Markov Chain is a type of machine learning algorithm that uses probability to model complex systems. It is based on the…
