In fact, up to two-thirds of the time taken in the data analytics process is spent cleaning what’s known as “dirty” data: data that needs to be edited, worked on, or otherwise manipulated before it’s suitable for analysis. During the cleaning phase, a data analyst may find outliers...
An outlier, in mathematics, statistics and information technology, is a specific data point that falls outside the range of probability for a data set. In other words, the outlier is distinct from other surrounding data points in a particular way. Outlier analysis is extremely useful in various...
A common misconception is that predictive analytics and machine learning are the same thing. Some may define predictive analytics as being the umbrella discipline and machine learning as being an extension. While bothdata sciencetechnologies aid in drawing meaningful conclusions from large datasets, each...

Sumo Logic is pleased to announce a new rule type for Cloud SIEM Enterprise (CSE): Outlier Rules. This new rule type further enhances CSE’s User and Entity Behavioral Analytics (UEBA) capabilities. With these rules, CSE can detect events that deviate from the usual behavior of an Entity, ...
insights for business decision-making. The data often is enriched and optimized to make it more informative and useful -- for example, by blending internal and external data sets, creating new data fields, eliminating outlier values and addressing imbalanced data sets that could skew analytics ...
Local Outlier Factor (LOF): Measures the local density of instances to identify outliers. Isolation Forest: Isolates anomalies by randomly partitioning the data into trees. Become a Professional Data Scientist Learn with our Comprehensive Certification Program ...
Anomaly detection,sometimes called outlier analysis, aims to identify rare or unusual data instances that deviate significantly from the expected patterns. It is useful in detecting fraudulent transactions, network intrusions, manufacturing defects, or any other abnormal behavior. ...
aggregate refers to the process of combining multiple elements into a single entity or summarizing data from various sources. it is commonly used in technology, computing, programming, and communications to analyze and present information in a meaningful way. how does aggregate work in data analysis...
To perform data filtering effectively, follow these steps: 1. Define Analysis Criteria Clearly articulate the specific criteria you aim to analyze. For instance, if the goal is to assess revenue by customer, determine the relevant time period and the specific customers to include in the analysis....
