📌 Self-Labeling in Semi-Supervised Learning Summary

Self-labelling in semi-supervised learning is a method where a machine learning model uses its own predictions to assign labels to unlabelled data. The model is initially trained on a small set of labelled examples and then predicts labels for the unlabelled data. These predicted labels are treated as if they are correct, and the model is retrained using both the original labelled data and the newly labelled data. This approach helps make use of large amounts of unlabelled data when collecting labelled data is difficult or expensive.

🙋🏻‍♂️ Explain Self-Labeling in Semi-Supervised Learning Simply

Imagine you are learning to sort fruit into apples and oranges, but you only have a few labelled examples. Once you get the hang of it, you start labelling the rest yourself and use those new labels to get even better at sorting. It is like practising with your own guesses to improve your skills, even if you started with only a little help.

📅 How Can it be used?

Self-labelling can help improve image recognition in a photo app by making use of many unlabelled pictures.

🗺️ Real World Examples

In medical image analysis, self-labelling can be used to train an AI to detect diseases from X-rays. With only a limited number of images labelled by doctors, the system predicts labels for thousands of unlabelled scans, then uses these predictions to further refine its accuracy and assist radiologists.

An e-commerce site uses self-labelling to improve its product categorisation system. Initially, only a small set of products are manually categorised, but the AI model predicts categories for the rest and retrains itself, leading to better product search and recommendations.

✅ FAQ

Self-labelling is a clever way for a machine learning model to teach itself. It starts off learning from a small set of examples where the answers are already known. Then, it tries to guess the answers for lots of new, unlabelled data. These guesses are treated like real answers, and the model uses them to get better. People use this approach because collecting labelled data can be time-consuming or expensive, and self-labelling helps make use of all the unlabelled data that is already available.

Yes, there can be risks. If the model makes mistakes when labelling new data, it could end up learning from its own errors. This can reinforce incorrect patterns and reduce accuracy. To help with this, researchers often use ways to check how confident the model is in its predictions and only keep the labels it is most sure about.

Using only labelled data can limit a model, especially when there is not much of it available. Self-labelling makes it possible to use a much larger pool of unlabelled data, which can help improve the model’s ability to learn. However, it is important to balance this with care so that mistakes do not creep in and affect the overall quality.

Risk Assessment Framework

A Risk Assessment Framework is a structured approach used to identify, analyse, and manage risks within an organisation or a project. It provides a set of processes and guidelines for evaluating potential threats and vulnerabilities, estimating their impact, and deciding how to address them. This framework helps organisations make informed decisions to minimise negative outcomes and protect their assets, people, and reputation.

Cloud Cost Optimization

Cloud cost optimisation is the process of reducing spending on cloud services while maintaining performance and reliability. It involves monitoring usage, identifying unnecessary resources, and adjusting configurations to avoid waste. The goal is to pay only for what is needed, making cloud spending more efficient and predictable.

Sales Companion

A Sales Companion is a digital tool or platform that helps salespeople during their interactions with customers. It provides information, resources, and guidance to support sales discussions and decision-making. Sales Companions can offer product details, pricing, sales scripts, or customer data to make meetings more effective and efficient.

Differentiable Neural Computers

Differentiable Neural Computers (DNCs) are a type of artificial intelligence model that combines neural networks with an external memory system, allowing them to store and retrieve complex information more effectively. Unlike standard neural networks, which process information in a fixed way, DNCs can learn how to read from and write to memory, making them better at tasks that require remembering sequences or handling structured data. This design helps DNCs solve problems that traditional models struggle with, such as learning algorithms or reasoning over long sequences.

Email Marketing Automation

Email marketing automation is the use of software to send emails to people automatically based on specific actions, schedules, or rules. This allows businesses to communicate with their audience without having to manually write and send each message. It helps save time and ensures that emails reach the right people at the right moment, such as welcoming new subscribers or reminding customers about abandoned shopping baskets.
