📌 Model Monitoring Summary
Model monitoring is the process of regularly checking how a machine learning or statistical model is performing after it has been put into use. It involves tracking key metrics, such as accuracy or error rates, to ensure the model continues to make reliable predictions. If problems are found, such as a drop in performance or changes in the data, actions can be taken to fix or update the model.
🙋🏻♂️ Explain Model Monitoring Simply
Imagine you have a robot that sorts fruit and you want to make sure it keeps doing a good job. Model monitoring is like watching the robot as it works to spot mistakes or changes so you can fix them before they become big problems. It is a way to keep an eye on your machine learning system to make sure it does not start making silly errors.
📅 How Can it be used?
Model monitoring can alert a team when a fraud detection system starts missing suspicious transactions due to changes in customer behaviour.
🗺️ Real World Examples
A bank uses a machine learning model to approve loan applications. Over time, as the economy shifts and customer profiles change, the model might start making less accurate decisions. By monitoring the model, the bank can spot when its performance drops and retrain it with more recent data to ensure fair and accurate loan approvals.
An online retailer uses a recommendation engine to suggest products to customers. If the system notices that fewer people are clicking on suggested items, model monitoring can identify this trend, prompting the team to investigate and improve the recommendations to better match customer interests.
✅ FAQ
Why is it important to keep an eye on how a model is performing after it has been put to use?
Models can behave differently once they start making decisions in the real world. Things like changes in customer preferences or new types of data can affect how well a model works. Regular monitoring helps spot these shifts early, so you can fix issues before they turn into bigger problems.
What are some signs that a model might not be working as well as it should?
Common signs include a drop in accuracy, more mistakes in predictions, or patterns in the data changing over time. If the results start to look less reliable or do not match what you expect, it is a good clue that the model needs attention.
What can you do if you notice your model is not performing as expected?
If a model is not doing its job properly, you can retrain it with newer data, adjust its settings, or even build a new version. The key is to act quickly, so the model stays helpful and trustworthy.

Bias Mitigation in Business Data
Bias mitigation in business data refers to the methods and processes used to identify, reduce or remove unfair influences in data that can affect decision-making. This is important because biased data can lead to unfair outcomes, such as favouring one group over another or making inaccurate predictions. Businesses use various strategies like data cleaning, balancing datasets, and adjusting algorithms to help ensure fairer and more accurate results.
Customer Journey Analytics
Customer Journey Analytics is the process of collecting and analysing data from every interaction a customer has with a business, across different channels and touchpoints. It helps companies understand how customers move through stages such as awareness, consideration, purchase, and after-sales support. By studying this journey, businesses can identify patterns, remove obstacles, and improve the overall customer experience.
Quote Manager
A Quote Manager is a tool or software feature that helps collect, organise, and manage quotations from various sources. It allows users to save, categorise, and retrieve quotes for reference, presentations, or projects. This can include famous sayings, book excerpts, customer testimonials, or price quotes used in business transactions.
Blockchain Network Bootstrapping
Blockchain network bootstrapping is the process of setting up and launching a new blockchain network from scratch. This includes configuring the initial nodes, defining the rules and parameters, and ensuring there are enough participants to make the network functional. Bootstrapping is crucial to ensure the network starts securely and operates as intended from the beginning.
AI for Astronomy
AI for Astronomy refers to the use of artificial intelligence methods to help astronomers analyse data, detect patterns, and make discoveries. Modern telescopes and space missions produce vast amounts of data that are too large for humans to examine without assistance. AI tools can quickly sort through images and signals, identify interesting objects like new planets or galaxies, and even predict cosmic events.
