📌 Model Quantization Trade-offs Summary
Model quantisation is a technique that reduces the size and computational requirements of machine learning models by using fewer bits to represent numbers. This can make models run faster and use less memory, especially on devices with limited resources. However, it may also lead to a small drop in accuracy, so there is a balance between efficiency and performance.
🙋🏻♂️ Explain Model Quantization Trade-offs Simply
Imagine trying to fit a detailed painting into a small suitcase by folding or compressing it. You save space, but some details might get lost. Model quantisation is similar: you make a model smaller and faster, but might lose a bit of its sharpness or accuracy.
📅 How Can it be used?
Model quantisation can help deploy a voice recognition system on smartphones by reducing model size while maintaining acceptable accuracy.
🗺️ Real World Examples
A company developing a language translation app for mobile phones uses quantisation to shrink their neural network, allowing users to run it offline without draining battery or using much storage.
An autonomous drone manufacturer applies quantisation to their object detection model, so it can process camera feeds in real time using limited onboard hardware.
✅ FAQ
Why would someone use model quantisation in machine learning?
Model quantisation helps make machine learning models smaller and faster, which is especially useful for running them on phones or other devices that do not have a lot of memory or processing power. By using fewer bits to store numbers, models can perform tasks more quickly and use less battery, although there might be a small trade-off in accuracy.
Does model quantisation always make models less accurate?
Quantisation can lead to a slight drop in accuracy, but the loss is often quite small, especially if the model is well-designed. For many everyday uses, the speed and efficiency gained from quantisation outweigh the minor decrease in accuracy.
What should you consider before applying quantisation to a model?
Before quantising a model, it is important to think about what matters most for your application. If you need a lightweight model that runs quickly and uses little memory, quantisation is very useful. However, if you cannot afford any loss in accuracy, you might want to test carefully or use higher precision where it matters most.

Zero Trust Architecture
Zero Trust Architecture is a security approach that assumes no user or device, inside or outside an organisation's network, is automatically trustworthy. Every request to access resources must be verified, regardless of where it comes from. This method uses strict identity checks, continuous monitoring, and limits access to only what is needed for each user or device.
Cutover Planning
Cutover planning is the process of preparing for the transition from an old system or process to a new one. It involves making sure all necessary steps are taken to ensure a smooth switch, including scheduling, communication, risk assessment, and resource allocation. The aim is to minimise disruptions and ensure that the new system is up and running as intended, with all data and functions transferred correctly.
Voice of the Customer (VoC) Analysis
Voice of the Customer (VoC) Analysis is the process of collecting and examining feedback from customers about their experiences, needs, and expectations with a product or service. It involves gathering information from surveys, reviews, support interactions, and social media to understand what customers value and where improvements can be made. The goal is to use these insights to guide decisions that enhance customer satisfaction and loyalty.
Mobile Apps
Mobile apps are software applications designed to run on smartphones and tablets. They are downloaded from app stores like Google Play or the Apple App Store and provide specific functions such as messaging, gaming, or banking. Mobile apps can work online or offline and are built to use the features of mobile devices, like cameras and GPS.
Intelligent Experience Analytics
Intelligent Experience Analytics refers to the use of advanced technologies, such as artificial intelligence and machine learning, to understand and improve how users interact with digital products or services. By automatically collecting and analysing data from user actions, these tools can identify patterns, preferences, and pain points. This helps businesses make decisions that lead to better customer satisfaction and more effective digital experiences.
