📌 Sharpness-Aware Minimisation Summary

Sharpness-Aware Minimisation is a technique used during the training of machine learning models to help them generalise better to new data. It works by adjusting the training process so that the model does not just fit the training data well, but also finds solutions that are less sensitive to small changes in the input or model parameters. This helps reduce overfitting and improves the model’s performance on unseen data.

🙋🏻‍♂️ Explain Sharpness-Aware Minimisation Simply

Imagine you are trying to balance a marble on a surface. If the surface is very sharp and pointy, the marble can fall off easily with a tiny nudge. If the surface is flatter and more stable, the marble stays put even if you bump the table. Sharpness-Aware Minimisation helps machine learning models find these flatter, more stable spots, so they do not make wildly different predictions if things change a little.

📅 How Can it be used?

Sharpness-Aware Minimisation can be used to train more robust image classifiers that perform well even with noisy or slightly altered input images.

🗺️ Real World Examples

A team building a handwriting recognition system for postal addresses uses Sharpness-Aware Minimisation to train their model. This makes the system more reliable when reading addresses written in different styles and with varying levels of clarity, improving accuracy and reducing errors in mail sorting.

A company developing a medical diagnosis tool for analysing X-rays applies Sharpness-Aware Minimisation during training. This helps ensure the model gives consistent results even when X-ray images vary in brightness or have minor artefacts, making it safer for clinical use.

✅ FAQ

Sharpness-Aware Minimisation is about training a machine learning model so it does not just do well on the training data but also stays reliable when faced with new or slightly different data. It encourages the model to find solutions that are less sensitive to small changes, making it more stable and trustworthy when used in real-world situations.

By looking for solutions that are not overly tuned to the quirks of the training data, Sharpness-Aware Minimisation helps the model avoid becoming too specialised. This means the model will be less likely to make mistakes when it sees new data, as it has learned to handle a wider range of possibilities rather than just memorising the training examples.

Generalisation is important because we want our models to perform well not only on the data they were trained on but also on new data they have never seen. Sharpness-Aware Minimisation supports this by guiding the model to solutions that are robust, so even small changes in the input or the model itself will not cause big drops in performance.

Dynamic Prompt Tuning

Dynamic prompt tuning is a technique used to improve the responses of artificial intelligence language models by adjusting the instructions or prompts given to them. Instead of using a fixed prompt, the system can automatically modify or optimise the prompt based on context, user feedback, or previous interactions. This helps the AI generate more accurate and relevant answers without needing to retrain the entire model.

Secure Data Federation

Secure data federation is a way of combining information from different sources without moving or copying the data. It lets users access and analyse data from multiple places as if it were all in one location, while keeping each source protected. Security measures ensure that only authorised people can view or use the data, and sensitive information stays safe during the process.

Privileged Access Management

Privileged Access Management, or PAM, is a set of tools and processes used to control and monitor access to important systems and data. It ensures that only authorised people can use special accounts with higher levels of access, such as system administrators. By limiting and tracking who can use these accounts, organisations reduce the risk of unauthorised actions or security breaches.

Supply Chain Attack

A supply chain attack is when a cybercriminal targets a business by exploiting weaknesses in its suppliers or service providers. Instead of attacking the business directly, the attacker compromises software, hardware, or services that the business relies on. This type of attack can have wide-reaching effects, as it may impact many organisations using the same supplier.

OAuth 2.1 Enhancements

OAuth 2.1 is an update to the OAuth 2.0 protocol, designed to make online authentication and authorisation safer and easier to implement. It simplifies how apps and services securely grant users access to resources without sharing passwords, by clarifying and consolidating security best practices. OAuth 2.1 removes outdated features, mandates the use of secure flows, and requires stronger protections against common attacks, making it less error-prone for developers.
