Weight
Definition of Weight Weight: In machine learning, weight is a factor that is assigned to a particular input in order to influence the strength of the associated output.
Waterfall Chart
Definition of Waterfall Chart Waterfall chart: A waterfall chart is a type of data visualization that shows how a starting value (in the y-axis) changes over time (in the x-axis) through a series of intermediary values. It’s often used to illustrate how different factors contribute to a final outcome.
Walking
Definition of Walking Walking: This is a term used in data science to describe the process of moving data from one location to another. It is often used when transferring data from a local machine to a remote server.
Vowel Removal
Definition of Vowel Removal Vowel Removal: Vowel removal is a data preprocessing technique used to remove vowels from text. This can be helpful for improving the accuracy of text-based machine learning models, as well as reducing the size of the training dataset.
Vector
Definition of Vector Vector: A vector is a mathematical object consisting of a set of points in a given space, each identified by a unique coordinate.
Vector Space Model
Definition of Vector Space Model Vector Space Model: A vector space model is a mathematical model used in statistics, data mining, and machine learning to describe a set of objects in terms of their attributes and relationships between them.
Variance
Definition of Variance Variance: Variance is a measure of how spread out a set of data points are. It is calculated by taking the difference between each data point and the mean, then squaring the results. This gives you a value that can be compared across different sets of data.
Variable
Definition of Variable Variable: A variable is a named entity that can take on different values. In data science, variables are often used to represent the attributes of objects in a dataset. For example, the age of a person might be represented by a variable called “age”.
Upstream
Definition of Upstream Upstream: Upstream and Downstream are terms used in data science to describe the flow of data or what order events occur. Data is processed and becomes more refined as it moves through the various processes. Upstream is closer to the source. When discussing a specific process step, Downstream is a term that…
UPF
Definition of UPF UPF: UPF stands for Uniform Probability Function. It is a mathematical function that assigns a probability to each outcome in a given set of outcomes.
