Фрагмент из книги:
The way we interact with technology has undergone a dramatic transformation. Gone are the days of complex interfaces and cryptic commands. Today, we're witnessing the exciting rise of conversational AI, where machines can understand and respond to natural language, paving the way for a more intuitive and engaging human-computer interaction experience.
At the heart of this revolution lie dialogue systems, intelligent programs capable of simulating conversation with humans. These systems are rapidly becoming ubiquitous, finding diverse applications across various industries.




Understanding Seq2seq: The Backbone of Conversational AI.
As we delve deeper into the realm of dialogue systems, we encounter a fundamental building block: sequence-to-sequence (seq2seq) models. These powerful neural networks are specifically designed to process one sequence of data (input) and generate another sequence (output), making them ideal for tasks like machine translation and, crucially for us, dialogue generation.

Imagine having a conversation with a friend who listens attentively to your words and then responds with thoughtful and coherent sentences. Seq2seq models operate similarly, processing the user's utterance (input sequence) and generating a meaningful response (output sequence). Here's how they achieve this remarkable feat:
The Encoder-Decoder Architecture: A Dance of Understanding and Response.
At the heart of a seq2seq model lies the encoder-decoder architecture.
Encoder: This part acts like a comprehension engine. It takes the user's utterance (input sequence) and processes it word by word, capturing the meaning and context of the entire sentence. It typically uses an RNN (Recurrent Neural Network) or a transformer architecture to achieve this.
