Out-of-Distribution Detection is a technique used to identify when a machine learning model encounters data that is significantly different from the data it was trained on. This helps to prevent the model from making unreliable or incorrect predictions on unfamiliar inputs. Detecting these cases is important for maintaining the safety and reliability of AI systems…

Knowledge Amalgamation
Knowledge amalgamation is the process of combining information, insights, or expertise from different sources to create a more complete understanding of a subject. This approach helps address gaps or inconsistencies in individual pieces of knowledge by bringing them together into a unified whole. It is often used in fields where information is spread across multiple…
Data Augmentation Strategies
Data augmentation strategies are techniques used to increase the amount and variety of data available for training machine learning models. These methods involve creating new, slightly altered versions of existing data, such as flipping, rotating, cropping, or changing the colours in images. The goal is to help models learn better by exposing them to more…
AutoML
AutoML, short for Automated Machine Learning, refers to tools and techniques that automate parts of the machine learning process. It helps users build, train, and tune machine learning models without requiring deep expertise in coding or data science. AutoML systems can handle tasks like selecting the best algorithms, optimising parameters, and evaluating model performance. This…
Ensemble Learning
Ensemble learning is a technique in machine learning where multiple models, often called learners, are combined to solve a problem and improve performance. Instead of relying on a single model, the predictions from several models are merged to get a more accurate and reliable result. This approach helps to reduce errors and increase the robustness…
Gradient Boosting Machines
Gradient Boosting Machines are a type of machine learning model that combines many simple decision trees to create a more accurate and powerful prediction system. Each tree tries to correct the mistakes made by the previous ones, gradually improving the model’s performance. This method is widely used for tasks like predicting numbers or sorting items…
Spectral Clustering
Spectral clustering is a method used to group data points into clusters based on how closely they are connected to each other. It works by representing the data as a graph, where each point is a node and edges show how similar points are. The technique uses mathematics from linear algebra, specifically eigenvalues and eigenvectors,…
Normalizing Flows
Normalising flows are mathematical methods used to transform simple probability distributions into more complex ones. They do this by applying a series of reversible steps, making it possible to model complicated data patterns while still being able to calculate probabilities exactly. This approach is especially useful in machine learning for tasks that require both flexible…
Causal Inference
Causal inference is the process of figuring out whether one thing actually causes another, rather than just being linked or happening together. It helps researchers and decision-makers understand if a change in one factor will lead to a change in another. Unlike simple observation, causal inference tries to rule out other explanations or coincidences, aiming…
Domain Adaptation
Domain adaptation is a technique in machine learning where a model trained on data from one environment or context is adjusted to work well in a different but related environment. This is useful when collecting labelled data for every new situation is difficult or expensive. Domain adaptation methods help models handle changes in data, such…
