Model Overview
Matchmeter is a machine learning model trained to distinguish between two classes of name strings: one provided by the merchant and the other from the end user’s bank record.
Class ‘1’ indicates that the two strings correspond to the same person, while class ‘0’ signifies that they do not match. Additionally, Matchmeter returns a metric on a scale from 0 to 100, expressing the degree of similarity between the strings, where 0 denotes completely different strings and 100 indicates a perfect match.
Model Performance
Recall and precision are metrics used for the evaluation of a machine-learning classifier.
- Recall in simple terms answers the question: Out of all the actual positive (negative) cases, how many did the model successfully detect?
Therefore, recall indicates how effectively the model detects all instances of a given class.
- Precision in simple terms answers the question: “Out of all the cases that the model predicted as positive (negative), how many were actually positive (negative)?
Therefore, precision indicates how accurate the model’s predictions are for a given class.
Our model has been optimised by default to maximise the recall metric for class ‘0’ (no match) We assume that the primary goal of the model is to detect all cases of incorrect registration or attempted fraud
Matching Example
The effectiveness of Matchmeter has been tested using a realistic dataset that preserves the distribution of bank popularity. However, it’s important to note that the results may vary depending on factors such as i.e. the quality of the shopper’s name provided.

| Amelia Grace Montgomery | Amelia Grace Montgomery | 1.0 |
| Amelia Grace Montgomery | Montgomery A G | 0.7634 |
| Amelia Grace Montgomery | Montgomery A | 0.75 |
| Amelia Grace Montgomery | Montgomer A | 0.6216 |
| Amelia Grace Montgomery | Montgom A | 0.2576 |
| Amelia Grace Montgomery | Montgomery | 0.2961 |
| Amelia Grace Montgomery | M Amelia Grace | 0.3544 |
