Definition of Prior Distribution A prior distribution is a probability distribution that is used to assign a probability to each outcome in a problem before any data is observed. This distribution is usually chosen based on experience or intuition.
Definition of Principal Component Analysis Principal component analysis (PCA) is a technique used to reduce the dimensionality of data. It does this by identifying the principal components of the data, which are the dimensions that account for the most variation in the data. PCA can be used to improve the performance of machine learning algorithms,…
Definition of Predictive Analytics Predictive analytics is the practice of using data mining and machine learning techniques to make predictions about future events. Predictive analytics can be used to predict things such as how likely a customer is to churn, or what the probability is that a particular disease will occur in a population.
Definition of Poisson Distribution The Poisson distribution is a discrete probability distribution that models the number of events that occur in a given time interval. The Poisson distribution is often used to model the number of clicks on a website, the number of phone calls received, or the number of emails sent in a given…
Definition of Pivot Table A pivot table is a data analysis tool that allows you to reorganize and analyze your data in a new way. With pivot tables, you can group and summarize data by column, or calculate new values based on existing data.
Definition of Perceptron A perceptron is a type of artificial neural network that can be used to learn and classify patterns. It is composed of a number of interconnected processing nodes, or neurons, that can be adjusted based on input data. The perceptron can be used to recognize patterns in data and make decisions accordingly.
