TensorFlow is an open-source software library for AI and machine learning with deep neuralnetworks. TensorFlow Lite also optimizes the trained model using quantization techniques (discussed later in this article), which consequently reduces the necessary memory usage as well as the computational cost of utilizing neuralnetworks.
As the name suggests, this technique involves transferring the learnings of one trained machine learning model to another, in the form of neuralnetwork weights. But, there are open source models like German-BERT that are already trained on huge data corpora, with many parameters. Book a demo to learn more.
Categorization of LLMs – Source One of the most common examples of an LLM is a virtual voice assistant such as Siri or Alexa. This early research was not about designing a system but exploring the fundamentals of Artificial NeuralNetworks. When you ask, “What is the weather today?”,
