Meena, the Google chatbot surpasses Siri and Alexa

Google is not far behind in a world where virtual assistants are gaining ground and has launched Meena, its new chatbot, which “talks about … can talk about anything” and arrives to compete with Alexa and Siri.

At present, both Amazon’s and Apple’s virtual assistants are market leaders, but Google is a marginal player in this field because, despite its attempts to enter this world with the arrival of its assistant, it could now have a big advantage over the rest.

Meena, the Google chatbot

According to the source, Meena is a thoroughly trained neural network model that Google has maintained for 30 days with 2,048 tensor processing units, Google’s special AI-specific chip, with over 340 GB of text, or nearly 40 billion words.

In addition, the source mentions that this processing power has given Meena the ability to understand the context of a conversation to the point where she can provide a coherent answer.

How coherent is Meena?

In order to evaluate the behavior offered by Meena, Google has developed a new metric called “Average Sensitivity and Specificity” or SSA that allows the Mountain View company to measure whether a bot’s response is meaningful, i.e., appropriate and more like a human response, and whether that response is specific.

For example, in a conversation like this, where the person says, “I love spy movies,” if the bot were to respond, “Great, tell me more,” that would be a reasonable response, but it’s not specific.

To this exclamation, however, Meena could reply: “Amazing. I like all the spy movies from Mission Impossible. Which one is your favorite?”, a more specific and appropriate answer.

Meena beats the rest

According to Google tests, Meena gave results that are closer to those of humans – how SSA can evaluate humans – this is 86%, i.e. this continuous neural network reached a level closer to humans with 79% SSA, while Mitsuku and Cleverbot reached 56%, DialoGPT 48% and XiaoIce 31%.

Although Meena is already running, Google is keeping this chatbot as a test version, so it will be a long time before Meena is publicly available.
