Anomaly Detection and Datamining

Image
Anomaly detection is a data mining technique that identifies data points that deviate from the norm. This can be used to identify fraud, errors, or unusual behavior. To apply anomaly detection in data mining, you can follow these steps: Define your anomalies. What do you consider to be an anomaly in your data? This could be a data point that is outside of a certain range, or a data point that has a different distribution than the rest of the data. Choose an anomaly detection algorithm. There are many different anomaly detection algorithms available. Some of the most popular algorithms include: Train the anomaly detection algorithm. The anomaly detection algorithm needs to be trained on a dataset of normal data points. This will allow the algorithm to learn what constitutes normal behavior. Test the anomaly detection algorithm on a dataset of known anomalies. This will help you to determine how well the algorithm performs at detecting anomalies. Deploy the anomaly detection algorith...

Association Rule Data Mining

Association rule mining is a rule-based machine learning method for discovering interesting relations between variables in large databases. It is intended to identify strong rules discovered in databases using some measures of interestingness. Association rule mining is a type of unsupervised machine learning that discovers interesting relationships between variables in large datasets. It is a rule-based approach that finds association rules, which are if-then statements that describe the relationship between two or more items. An association rule has two parts: The antecedent (the "if" part) is a set of items that must occur together. The consequent (the "then" part) is an item that is likely to occur if the antecedent is present. For example, an association rule for a supermarket might be: If a customer buys diapers, then they are likely to also buy beer. This rule tells us that there is a strong association between the purchase of diapers and beer. This informati...
