While effective for basic applications, these models lack long-term coherence. More advanced models include recurrent networks like LSTMs and GRUs, which generate text one word at a time while preserving memory of previous inputs.
However, the real transformation in language generation came with transformer-based models. TensorFlow supports the training and deployment of these models, including GPT-style architectures that generate coherent, grammatically correct, and contextually appropriate text. The attention mechanism in transformers allows the model to consider all previous tokens when generating the next word, significantly improving fluency and consistency. Training language generation models involves defining a sequence-to-sequence structure where the input is a prompt or context, and the output is a generated sequence. The model is optimized using teacher forcing during training and greedy decoding or beam search during inference.
Dialogue systems or chatbots are a specialized application of language generation. These systems must not only generate grammatically correct responses but also maintain context across multiple conversational turns. TensorFlow provides the infrastructure to build rule-based, retrieval-based, and generative dialogue systems. Rule-based systems rely on predefined patterns and templates, while retrieval-based systems choose the best response from a database. Generative models, often powered by sequence-to-sequence or transformer architectures, create responses from scratch and are more flexible but harder to control. TensorFlow enables the integration of reinforcement learning to train dialogue agents that learn from user feedback and improve their conversational abilities over time.
Evaluation of language generation models is another important aspect. Metrics like BLEU, ROUGE, and perplexity are commonly used to assess the quality and relevance of generated text.
