📌 Zero-Shot Learning Summary
Zero-Shot Learning is a method in machine learning where a model can correctly recognise or classify objects, actions, or data it has never seen before. Instead of relying only on examples from training data, the model uses descriptions or relationships to generalise to new categories. This approach is useful when it is impossible or expensive to collect data for every possible category.
🙋🏻♂️ Explain Zero-Shot Learning Simply
Imagine you are told about a new animal that you have never seen, like a platypus, and someone describes its features to you. Later, if you see a picture of a platypus, you could recognise it using the description, even though you have never seen one before. Zero-Shot Learning works in a similar way, letting computers identify things they have only learned about through descriptions, not direct examples.
📅 How Can it be used?
Zero-Shot Learning can be used in an image recognition system to identify rare or new species without needing images of every species for training.
🗺️ Real World Examples
A language translation app can use Zero-Shot Learning to translate between languages it was not directly trained on by relying on shared features and relationships between known languages. This allows the app to support new language pairs without needing huge datasets for each possible combination.
In medical diagnosis, Zero-Shot Learning helps AI systems suggest potential diseases that were not in their training data by linking symptoms and medical knowledge, aiding doctors in recognising rare conditions.
✅ FAQ
What is zero-shot learning and why is it useful?
Zero-shot learning is a clever way for computers to recognise things they have never seen before by using descriptions or relationships instead of just examples. This is especially useful when it is difficult or expensive to collect data for every possible object or action, so the computer can still make sense of new things based on what it already knows.
How does zero-shot learning work if the model has never seen some categories?
Zero-shot learning works by teaching the model about the features or descriptions of different categories, rather than just showing it lots of examples. When the model comes across something new, it uses these descriptions or relationships to figure out what it might be, even if it has never seen it before.
Where might zero-shot learning be helpful in real life?
Zero-shot learning can help in situations like recognising rare animals in wildlife photos, understanding new words in language processing, or identifying products in online shops that have just been added. By not needing lots of new data for every possible case, it makes technology more flexible and efficient.

Enterprise Service Bus
An Enterprise Service Bus (ESB) is a software system that helps different computer programmes within a company communicate and share data. It acts as a central hub, allowing various applications to connect without needing to know the technical details of each other. By using an ESB, businesses can integrate their systems more easily, making it simpler to update or replace individual parts without disrupting the whole network.
Quantum Error Calibration
Quantum error calibration is the process of identifying, measuring, and adjusting for errors that can occur in quantum computers. Because quantum bits, or qubits, are extremely sensitive to their environment, they can easily be disturbed and give incorrect results. Calibration helps to keep the system running accurately by fine-tuning the hardware and software so that errors are minimised and accounted for during calculations.
Enterprise Digital Platforms
Enterprise digital platforms are large-scale software systems that help businesses run their operations more efficiently. They provide a central place for employees, customers, and partners to access tools, share information, and manage workflows. These platforms often connect different business functions like sales, finance, HR, and customer service so that data and processes flow smoothly across the organisation.
Ethical Usage Monitor
An Ethical Usage Monitor is a tool or system designed to track, review, and ensure that technology and data are being used in ways that align with ethical guidelines and standards. It observes user actions, data processing, or system outputs to detect behaviour that could be considered harmful, unfair, or non-compliant with ethical policies. By providing oversight, it helps organisations maintain trust, avoid misuse, and act responsibly when using technology or data.
Process Optimization Metrics
Process optimisation metrics are measurements used to evaluate how effectively a process is working. These metrics help identify areas where improvements can be made to increase efficiency, reduce waste or improve output quality. By tracking these numbers over time, organisations can make informed decisions to streamline operations and achieve better results.
