📌 Model Lag Summary
Model lag refers to the delay between when a machine learning model is trained and when it is actually used to make predictions. This gap means the model might not reflect the latest data or trends, which can reduce its accuracy. Model lag is especially important in fast-changing environments where new information quickly becomes available.
🙋🏻♂️ Explain Model Lag Simply
Imagine you study for a test using last year’s textbook, but the teacher has updated the material since then. Your answers might be out of date because you did not have the newest information. Model lag is like using an old textbook when the world has already moved on.
📅 How Can it be used?
Monitor and minimise model lag to keep prediction results relevant and accurate in dynamic data environments.
🗺️ Real World Examples
A retail company uses a model to predict product demand, but if the model is not updated with recent sales data, it may miss new shopping trends, leading to overstock or shortages.
A bank uses a fraud detection model trained on last year’s transaction data, but as scammers change tactics, the model’s effectiveness drops if it is not retrained regularly, allowing more fraudulent transactions to slip through.

Compliance Heatmap
A compliance heatmap is a visual tool that shows how well an organisation is meeting regulatory or internal requirements. It uses colours or shading to highlight areas of strong or weak compliance across different departments, processes, or controls. This helps managers quickly identify problem areas and prioritise actions to reduce risks.
Protocol Fuzzing
Protocol fuzzing is a method used to test the security and reliability of communication protocols by automatically sending large amounts of random or unexpected data to them. This helps uncover hidden bugs, vulnerabilities, or weaknesses that might not be found through regular testing. By exposing how a protocol handles unusual input, developers can fix problems before they are exploited.
Temporal Data Modeling
Temporal data modelling is the process of designing databases or data systems to capture, track and manage changes to information over time. It ensures that historical states of data are preserved, making it possible to see how values or relationships have changed. This approach is essential for systems where it is important to know not just the current state but also the past states of data for auditing, reporting or compliance purposes.
Payment Processing
Payment processing refers to the steps taken to complete a financial transaction when a customer pays for goods or services using a card or digital method. It involves securely transferring payment information from the customer to the merchant, and then to the bank or payment provider. The process ensures that money moves from the customer's account to the merchant's account, confirming that payment is valid and approved.
Private Set Intersection
Private Set Intersection is a cryptographic technique that allows two or more parties to find common elements in their data sets without revealing any other information. Each party keeps their data private and only learns which items are shared. This method is useful when data privacy is important but collaboration is needed to identify overlaps.
