📌 Model Performance Tracking Summary
Model performance tracking is the process of monitoring how well a machine learning or statistical model is working over time. It involves collecting and analysing data about the model’s predictions compared to real outcomes. This helps teams understand if the model is accurate, needs updates, or is drifting from its original performance.
🙋🏻♂️ Explain Model Performance Tracking Simply
Imagine you are keeping a scorecard for your favourite football player to see how well they play each game. Model performance tracking is like that scorecard, but for a computer model, helping you see if it keeps making good predictions or if its skills are slipping. By checking its scores regularly, you know when it is time to practise or change tactics.
📅 How Can it be used?
Model performance tracking can ensure an automated spam filter continues to correctly identify unwanted emails as new types of spam appear.
🗺️ Real World Examples
An online retailer uses a product recommendation model to suggest items to shoppers. By tracking the model’s performance, the retailer notices a drop in click-through rates and discovers that customer preferences have shifted, prompting a model update to improve recommendations.
A hospital deploys a machine learning model to predict patient readmissions. By monitoring the model’s performance, the hospital identifies a gradual decrease in accuracy, which leads to retraining the model with more recent patient data to maintain reliable predictions.
✅ FAQ
Why is it important to keep track of how well a model is working?
Keeping an eye on a models performance helps you spot problems early. If a model starts making more mistakes or drifts away from how it worked before, you can catch it before it causes bigger issues. This means better results and more trust in what the model is doing.
What are some signs that a model might need an update?
If you notice the models predictions are not matching real outcomes as closely as before, or if it starts to make mistakes in new situations, these are signs it might need a refresh. Sometimes changes in the data or the world mean the model needs to be retrained or adjusted.
How often should you check a models performance?
It is a good idea to check your models performance regularly, not just when something goes wrong. How often depends on how important the model is and how quickly things can change in your data. For some models, weekly or monthly checks are enough, while others might need daily monitoring.

Data Literacy Programs
Data literacy programmes are organised efforts that teach people how to understand, interpret and use data effectively. These programmes focus on building skills such as reading charts, recognising patterns, and drawing meaningful conclusions from information. They can be delivered through workshops, online courses, or ongoing training in workplaces or schools. Having data literacy helps individuals make informed decisions and communicate more clearly using facts and figures.
Deep Residual Learning
Deep Residual Learning is a technique used to train very deep neural networks by allowing the model to learn the difference between the input and the output, rather than the full transformation. This is done by adding shortcut connections that skip one or more layers, making it easier for the network to learn and avoid problems like vanishing gradients. As a result, much deeper networks can be trained effectively, leading to improved performance in tasks such as image recognition.
Target Operating Model
A Target Operating Model (TOM) is a detailed description of how an organisation wants to run its operations in the future. It outlines the structure, processes, technology, people, and information needed to achieve strategic goals. The TOM serves as a blueprint for change, helping guide decisions and investments as an organisation moves from its current state to its desired future state.
Edge AI Deployment
Edge AI deployment means running artificial intelligence models directly on devices like smartphones, cameras or sensors, instead of sending data to remote servers for processing. This approach allows decisions to be made quickly on the device, which can be important for tasks that need fast response times or for situations where there is limited internet connectivity. It also helps keep sensitive data local, which can improve privacy and security.
Transformer Decoders
Transformer decoders are a component of the transformer neural network architecture, designed to generate sequences one step at a time. They work by taking in previously generated data and context information to predict the next item in a sequence, such as the next word in a sentence. Transformer decoders are often used in tasks that require generating text, like language translation or text summarisation.
