Python
Definition of Python Python is a high-level programming language with strong support for data science and machine learning. It has a wide variety of libraries for data analysis, machine learning, and scientific computing.
Prior Distribution
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.
Principal Component Analysis
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,…
Predictive Analytics
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.
Poisson Distribution
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…
Pivot Table
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.
Perl
Definition of Perl Perl is a programming language that is used for text processing, system administration, and web development. It is known for its powerful regular expression capabilities.
Perceptron
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.
Pandas
Definition of Pandas Pandas is a software library written for the Python programming language that enables data analysis. It provides high-performance, easy-to-use data structures and data analysis tools for the Python programming language. Pandas is free software released under the 3-clause BSD license.
PageRank
Definition of PageRank PageRank is a link analysis algorithm created by Google co-founder Larry Page. It assigns a numerical weight to each page in order to determine its importance within the web. The algorithm is based on the idea that important pages will be linked to by other important pages.
