📌 Model Calibration Metrics Summary
Model calibration metrics are tools used to measure how well a machine learning model’s predicted probabilities reflect actual outcomes. They help determine if the model’s confidence in its predictions matches real-world results. Good calibration means when a model predicts something with 80 percent certainty, it actually happens about 80 percent of the time.
🙋🏻♂️ Explain Model Calibration Metrics Simply
Think of a weather app that says there is a 70 percent chance of rain. If it is well-calibrated, it should rain on 7 out of 10 such days. Model calibration metrics check if predictions like these match what really happens, making sure the model is trustworthy.
📅 How Can it be used?
Model calibration metrics can be used to improve the reliability of risk predictions in a healthcare decision support tool.
🗺️ Real World Examples
In credit scoring, banks use model calibration metrics to ensure that when their model predicts a 10 percent chance of loan default, about 10 percent of those customers actually default. This helps the bank make fair and accurate lending decisions.
In weather forecasting, meteorologists use calibration metrics to check if a model’s predicted probabilities for rain or storms match the observed frequencies, helping them provide more reliable forecasts to the public.

Latent Prompt Injection
Latent prompt injection is a security issue affecting artificial intelligence systems that use language models. It occurs when hidden instructions or prompts are placed inside data, such as text or code, which the AI system later processes. These hidden prompts can make the AI system behave in unexpected or potentially harmful ways, without the user or developers realising it.
Model Compression Pipelines
Model compression pipelines are a series of steps used to make machine learning models smaller and faster without losing much accuracy. These steps can include removing unnecessary parts of the model, reducing the precision of calculations, or combining similar parts. The goal is to make models easier to use on devices with limited memory or processing power, such as smartphones or embedded systems. By using a pipeline, developers can apply multiple techniques in sequence to achieve the best balance between size, speed, and performance.
Network Protocol Hardening
Network protocol hardening is the process of making communication protocols more secure by reducing vulnerabilities. It involves configuring settings, disabling unnecessary features, and ensuring only secure versions of protocols are used. This helps protect data as it travels between devices and reduces the risk of cyber attacks exploiting weak points in the network.
State Channels
State channels are a technique used in blockchain systems to allow two or more parties to carry out multiple transactions without needing to record each one on the blockchain. Instead, the parties communicate directly and only add the final result to the blockchain. This reduces costs and avoids delays caused by waiting for blockchain confirmations. State channels help improve scalability by taking frequent or repetitive transactions off the main blockchain, making them faster and cheaper for users.
Business-led QA Strategy
A business-led QA strategy is an approach to quality assurance where the needs and goals of the business are placed at the centre of all testing and quality processes. Instead of focusing only on technical requirements, this strategy ensures that testing aligns with what delivers value to customers and meets business objectives. It encourages collaboration between technical teams and business stakeholders to prioritise the most important features and risks.
