Data governance
Data governance is the set of rules, processes, roles and technologies put in place to ensure the effective management, quality, security and compliance of data in an organisation.
GPU
A GPU (Graphics Processing Unit), or graphics processor, is a specialised hardware component originally designed to accelerate graphics rendering in games and 3D applications.
In the field of AI, GPUs are essential for their ability to perform massive parallel calculations, optimising the training and execution of deep learning models and neural networks.
Hallucination
A hallucination in AI refers to a phenomenon where a generative AI model (such as LLM) produces incorrect, incoherent or totally invented information, while presenting it as factual.
These errors stem from the very nature of LLMs, which are designed to predict statistically plausible rather than verified responses.
