Complete Idea
LaMDA is a language model. In natural language processing, a language model analyzes the use of language.Fundamentally, it’s a mathematical function (or a statistical tool) that describes a possible outcome related to predicting what the next words are in a sequence.It can also predict the next word occurrence, and even what the following sequence of paragraphs might be.OpenAI’s GPT-3 language generator is an example of a language model.With GPT-3, you can input the topic and instructions to write in the style of a particular author, and it will generate a short story or essay, for instance.LaMDA is different from other language models because it was trained on dialogue, not text.As GPT-3 is focused on generating language text, LaMDA is focused on generating dialogue.
Platform Breakthrough
What makes LaMDA a notable breakthrough is that it can generate conversation in a freeform manner that the parameters of task-based responses don’t constrain.A conversational language model must understand things like Multimodal user intent, reinforcement learning, and recommendations so that the conversation can jump around between unrelated topics.
Technology on which it is built
Similar to other language models (like MUM and GPT-3), LaMDA is built on top of the Transformer neural network architecture for language understanding.
Understanding Conversation
BERT is a model that is trained to understand what vague phrases mean.LaMDA is a model trained to understand the context of the dialogue.This quality of understanding the context allows LaMDA to keep up with the flow of conversation and provide the feeling that it’s listening and responding precisely to what is being said.
How it impersonates Human Dialogue ?
The engineer who claimed that LaMDA is sentient has stated in a tweet that he cannot support those claims, and that his statements about personhood and sentience are based on religious beliefs.In other words: These claims aren’t supported by any proof. The proof we do have is stated plainly in the research paper, which explicitly states that impersonation skill is so high that people may anthropomorphize it.The researchers also write that bad actors could use this system to impersonate an actual human and deceive someone into thinking they are speaking to a specific individual.
