# Association Rule Learning with Apriori

This repository contains a command-line application written in Dart that

uncovers the association rules within a list of transactions.

## Getting Started

### Install the Application

```

cd ..

```

```

dart pub global activate apriori -s=path

```

### Prepare Input Files

You need to prepare two files:

- A JSON file containing your transactions

- A JSON file containing your settings and preferences

#### Transactions Scheme

```ts

type Transactions = string[][];

```

#### Options Scheme

```ts

type Options = {

  transactionsPath: string;

  rulesPath: string;

  minSupport: number;

  minConfidence: number;

  maxAntecedentsLength: number;

};

```

### Run the Application

You can run the application using the following command:

```

apriori options.json

```

## Example

### `transactions.json`

```json

[

  ["tropical fruit", "yogurt", "coffee"],

  ["whole milk"],

  ["pip fruit", "yogurt", "cream cheese", "meat spreads"]

]

```

### `options.json`

```json

{

  "transactionsPath": "transactions.json",

  "rulesPath": "rules.json",

  "minSupport": 0.006,

  "minConfidence": 0.07

}

```

### Learning the Association Rules

```

apriori options.json

```

You can look at [`example/`](./example/) for more information.

## Performance

This application can extract and learn the association rules within the

transactions at [`example/`](./example/) in ~55 seconds.
