How AI Training Data Centers Work
AI training data centers are a critical component in the development of AI models. They require densely connected, network-rich data centers that serve as a funnel between endpoints and AI-workloads.
To train AI models, data needs to be uncorrupted, trusted, voluminous, and, depending on the use case, real-time. This is because AI models are being trained with unstructured data collected from all types of endpoints, and all that data will be very useful in the future.
The process of training AI models involves three phases: data preparation, AI training, and AI inference. During the AI training phase, the AI model learns patterns and relationships within the training data to develop virtual synapses to mimic intelligence.
