Single-Turn Turing Test
The Turing Test has been an incredibly famous metric to evaluate and get a glimpse of how an AI actually would look like, but as we move closer to the horizon and with how effective Large Language Models can actually be in real life scenarios, we go back again to the 1950s where the Turing Tests states:
The test is designed to determine whether a machine can imitate human responses well enough that a human judge cannot reliably distinguish between the machine and another human based solely on the content of their responses.
A variant of this test, known as the Single-Turn Conversation Turing Test, has emerged to evaluate machine performance in a more concise and focused manner. The main catch here is that the conversation between the machine and human are present in a single isolated dialogue exchange. In this test, a human judge interacts via text with both a machine and another human participant without knowledge of which is which. As the name suggests, the judge (human) exchanges only once with the machine and the respondent and the response is evaluated. Looks simple, right? It is!
Benefits
Simplicity : No research text required, no book. I could explain it in one line and that’s it! It provides a very simple way to evaluate chat based model performance. I believe there are limitations to this but let’s wait for the fun to end 😝
Practical: In cases where the chatbot just needs to mimic humans and are standard business use cases like service, insurance, warranty etc. These do not require state of the art capabilities. So probably take a smaller more useful for the scenario model?
Limitations
Only Superficial : With the great LLMs we have right now, It is safe to say that all those text based interacting models are already this test compliant. So more robust evaluation methods are applicable to these models/
Performance v/s Understanding: Does it really understand my problem or is just very polite like a human but does not answer my question? This test fails to explain the fine intricacies of the response.
What’s Next?
Some other more standard evaluation metrics are:
- BLEU Score
- Perplexity
One cool read could be : The inverted Turing test
