Data Mining – Association Rule Mining(ARM) | Apriori Algorithm with a simple example

What Is Association Rule Mining?

What is association rule mining? Simply put, it is the process of analyzing a data set to discover correlations between different items. It has many uses and applications, from medical diagnosis to sales correlations in transactional data. Association rules can be helpful for doctors in diagnosing patients because some diseases share symptoms and can help to make the diagnosis. The results of this research can be used to develop personalized treatment plans for patients. The machine learning models that are used to analyze the data will adjust the rules to reflect the latest information.

what is association rule mining

Association rule mining is one method of analyzing databases to identify the most effective marketing strategies. Using the data from censuses, businesses can better plan public services and businesses. It can also be used to plan the development of new factories, shopping centers, or marketing products. The potential of association rule mining is huge, and it can support sound public policies and an efficient democratic society. If you’re a business owner looking to increase your sales, take a look at these methods.

Example of association

An example of association rule mining is the analysis of web logs. These databases can provide information on stocks, customer market analysis, and medical diagnosis. Fuzzy and Boolean algorithms have been developed to help with this process. The Apriori algorithm, for example, uses the Minimum-Support parameter. This parameter can be used to help define the strength of an association rule. If an association rule has high confidence, it is likely to be valid.

Used Of Association rule mining

Association rule mining is used to identify relationships between different items in a dataset. For example, a fast food chain learned that customers are likely to purchase a Coke after eating their meals. This led to the creation of combo meals. These meals were created to maximize the number of purchases and increase revenue. It is important to consider how associations and correlations are discovered in any dataset. This data can help you develop strategies to boost your sales.

The association rule mining method uses a meta-rule to detect multiple-level associations in a database. It is a rule-based machine learning method that is used to find patterns in a large database. The method can be applied to media recommendations and webpage analysis. It is a two-step process that utilizes a shopping cart item as the key factor. Then, it can be adapted to any scenario.

Techopedia explains Association Rule Mining

Assocation rule mining is data mining that identifies the rules that govern causal objects and associations between items.

It will then attempt to determine the rules for buying multiple items together in a transaction. Peanut butter and jelly, for example, are often purchased together as a result of the popularity of peanut butter and jelly in PB&J sandwiches.

Not surprisingly, diapers can be bought together as the dads often have to shop while the moms take care of the baby.

These are the main uses of association rule mining

  • Basket data analysis – This is the process of analysing the relationship between purchased items and a basket, or purchase as in the above examples.
  • Cross marketing is when you work with businesses that complement yours, and not with competitors. Cross marketing is a common strategy used by vehicle manufacturers and dealers to market their products and services to oil and gas companies.
  • Catalog design is the art of selecting items that complement each other in a business’ catalogue. This allows customers to buy one item and then purchase another. These items can often be complemented or very closely related.

FP-Tree are both algorithms that use the Apriori algorithm to find frequent items in a database. In a logical database, an association rule is a pattern between two items that tend to occur together. Hence, a PB&J is an example of an association rule. Similarly, beer and a diaper are examples of frequent items in a dataset.

An association rule is a pattern between two or more items. In the case of a supermarket, this rule will be useful for predicting the behavior of customers. It is used in many areas, including customer analytics. It can be used in catalogs and store layout. The algorithm will also be useful for other applications. Ultimately, this method is meant to improve efficiency in artificial intelligence programs. If the system can predict a consumer’s preferences, it will be more profitable for the business.

The Apriori algorithm has many limitations. First, it produces very dull rules, which is not very useful for a variety of applications. It has high-dimensional data, and it is unable to recognize associations between items. It has an infinite number of potential combinations, and it is used to detect novel patterns in large data sets. The Apriori algorithm is the most popular algorithm for association rule mining. It is simple and accurate.

Apriori is the most common type of association rule mining algorithm. It uses the prior knowledge of frequent itemsets to identify those that are unlikely to be associated. It uses candidate itemsets to explore (k+1)-itemsets. Apriori algorithm requires repeated database scans to identify associations. It is not known for its skewed results, but it does show associations between things. Its outputs are usually referred to as “association rules”.
