Google Sparrow Vs. Bard: Similarities And Differences

New advances in AI chatbots are happening quickly and are often being reported in the news.

Google Bard and Sparrow are two AI chatbots that are powered by different versions of Google’s Language Model for Dialogue Applications (LaMDA), a large language model (LLM) that can generate natural and fluent responses to any kind of prompt.

They have some similarities in their features and goals but also some differences.

What Is Google Sparrow?

Sparrow is an AI chatbot developed by Google subsidiary DeepMind that uses advanced Natural Language Processing(NLP) techniques.

It is based on the GPT-3 model designed to analyze the received text from the users and generate the responses.

Sparrow was introduced in September 2022 in a paper; regardless, it is in the research phase and has not been released publicly.

DeepMind CEO Demis Hassabis says a private beta version of Sparrow will be released in 2023.

Moreover, it can learn and draw information from Google searches. Besides, this model pays attention to accuracy, safety and practicality.

Unlike other chatbots that have gained popularity, Sparrow hasn’t been able to generate as much buzz due to the absence of a public API with it.

It is a research project to showcase the potential of an advanced language model for chatbots.

How Does Google Sparrow Work?

Sparrow is designed to talk with users, answer queries and search for information using Google.

The training model in Sparrow is similar to that of ChatGPT.

Meanwhile, it follows RLHF (Reinforcement learning from Human Feedback) protocols and large language models.

The working model of Google Sparrow is described below;

1. Pre-Training Language Models

RLHF is based on people’s feedback which is used to train Sparrow.

Deepmind has set rules for Sparrow, such as not making threatening statements and hateful comments to make the model safe.

Additionally, Sparrow is trained with a rule model to indicate when it breaks the rules. This is done by asking participants to try and trick Sparrow.

This model shows answers with or without evidence retrieved from the internet and also determines when the answer should be supported with the evidence.

Sparrow presents four possible answers without supporting evidence when prompted with a query and initiates two Google search queries that could potentially yield two relevant results.

2. Reward Model Training

For each search, these results are conditionally sampled.

All results are scored by a Preference Reward and Rule Reward models, and the highest-scored result is shown to the users.

According to the participants, Sparrow’s answers are credible and support 78% of the evidence of the time.

Despite its capabilities, Sparrow is not immune to being fooled or tricked by participants, indicating that there is still room for improvement in its design and functionality.

What Is Google Bard?

Google Bard is a conversational AI service powered by LaMDA (Language Model for Dialogue Applications) that aims to build advanced analytics to produce information.

Its main goal is to retrieve information simply, like a digital assistant.

Moreover, it provides human-like conversational responses and generates and edits text.

Bard can access Google’s search engine. It is more likely to compete with Microsoft’s new AI Bing Chat, which can access the entire web.

However, you cannot see the citations footnote with the information links.

How Does Google Bard Work?

Google Bard can only handle U.S. English language. Bard’s response addresses NORA questions which means No One Right Answer.

Here is how the Google Bard model works;

1. Flow Of Information

Bard provides the Knowledge Graph Card in the search when making queries that have simple answers, such as word definitions or overviews about a person or place.

Moreover, you can help the Bard chatbot by using the thumbs-up or thumbs-down buttons.

You can even regenerate the answers, just like in ChatGPT. Alternatively, you can click the Google It button for a regular search.

Bard chatbot also have a drafts option that allows you to select from the different answer in bullet format. A Reset chat button exists to terminate and start a new chat session.

Further, you can access the Bard Activity, which allows seeing the history of your searches.

There is not much documentation about how Google has refined the technology for use in Bard; however, you can find documentation on how large language model works.

2. Training Data Set

Bard first uses the LaMDA language model to understand the queries and then draws the information it finds across the web to form a conversational reply.

It uses a type of neural network called a Transformer to understand and generate human-like language.

Training data works by enabling LaMDA to learn from a large amount of data enabling it to achieve objectives, quality and safety.

3. Pre-Training

In the pre-training process, LaMDA is trained on a large dataset of 1.56 trillion words from public dialog data and public web documents.

This dataset covers a wide range of topics and domains. It also helps LaMDA learn general knowledge and skills.

4. Fine Training

LaMDA is trained to perform generative and classification tasks in the fine-tuning process.

Generative tasks produce natural language responses to give contexts, while classification tasks predict each response’s safety and quality.

In this way, LaMDA learns how to generate responses and avoid inappropriate responses.
