🧠 Why MindsDB?

We chose MindsDB as it was a requirement for the hackathon organized by Hashnode in collaboration with MindsDB. While it might seem a bit challenging initially, once you get comfortable with MindsDB, you'll love its features. MindsDB offers a wide range of data sources, AI engines, and integration handlers that allow you to build your own AI applications. You can create your own models by training them with large datasets tailored to your specific needs. MindsDB also supports popular AI engines like OpenAI and Hugging Face.

A cool aspect of MindsDB is that it's an open-source project, meaning anyone can contribute by adding their data sources, handlers, or AI engines to the official MindsDB repository. This flexibility allows users to easily customize and create their AI applications.

πŸ€– How We Used MindsDB:

We use MindsDB for various tasks, such as extracting YouTube comments and optimizing OpenAI models for specific purposes. Initially, we perform all the necessary tasks and testing using MindsDB's GUI editor through SQL commands. The models trained and optimized in the GUI editor are then accessed and utilized in our web application through MindsDB's JavaScript SDK. This SDK acts as a connection system to link the models with our back-end server. Here are some of the secret codes we used to make all this happen:

  1. For Fetching Youtube Comment's

-- Creating Datasource of youtube
CREATE DATABASE mindsdb_youtube
WITH ENGINE = 'youtube',
  "youtube_api_token": '-Your Youtube Developer Api key-'  

-- For fetching the youtube comments of respective channel
SELECT * FROM mindsdb_youtube.comments
WHERE video_id = "Video ID";
  1. For Creating the ML engine of OpenAi

-- This engine is used throughout of your application
CREATE ML_ENGINE openai_engine
FROM openai
   api_key = 'Your OpenAi API key';
  1. For comment Analysis

-- This model is used to extract sentiment of 5 comments per request
CREATE MODEL mindsdb.comment_analyzer
PREDICT sentiment
  engine = 'openai_engine',
  model_name = 'gpt-4',
  prompt_template = 'Evaluate the sentiment of the following comment segments enclosed by {} and separated by &. Provide only one sentiment for each comment, strictly choosing one out of these sentiments: Appreciation, Hate, Neutral, Spam. Avoid offering any explanations. If {comment1}& {comment2}& is passed, the response should be sentiment1, sentiment2. If {comment1}& {comment2}& {comment3}& {comment4}& {comment5}$ is passed, the response should be sentiment1, sentiment2, sentiment3, sentiment4, sentiment5. Ensure that this format remains consistent for all comments, and the maximum number of comments to be passed is up to 5 - {{comment}}';
  1. For extracting summary of blog and youtube

-- This model is used to extract the summary of youtube video through transcript
CREATE MODEL mindsdb.text_summary
PREDICT summary
  engine = 'openai_engine',
  model_name = 'gpt-4',
  prompt_template = 'Summarize the content of the YouTube video using transcript in short and strictly donot give incomplete summary - transcript: {{transcript}}';

-- This model is used to extract summary of blog through markdown
CREATE MODEL mindsdb.blog_summary
PREDICT summary
  engine = 'openai_engine',
  model_name = 'gpt-4',
  prompt_template = 'Summarize the content of the blog using markdown in short and strictly donot give incomplete summary - markdown: {{markdown}}';

βž• Add on:

Knowledge Base: It is a repository of learned representations or embeddings, usually created by training an embedding model on relevant data. This knowledge can be used by the agent to understand and respond to user inputs.

Skills: These are specific capabilities or tasks associated with the AI agent. Skills define how the agent can use its knowledge to perform various tasks, and they are often linked to models or knowledge bases.

CREATE KNOWLEDGE BASE command is used to create a knowledge base from an embedding model, and the CREATE SKILL command is used to define specific skills that utilize knowledge bases or other resources for tasks like sentiment analysis or text summarization. The agent is then configured with these skills to enable it to respond intelligently to user input.

-- Create an ML Engine for OpenAI
    CREATE ML_ENGINE openai_engine
    FROM openai
        api_key = 'sk-.................';

-- Create an embedding model for the knowledge base
    CREATE MODEL mindsdb.embedding_model
    PREDICT embeddings
       engine = 'openai_engine',
       question_column = 'content';

-- Create a knowledge base using the embedding model
    CREATE KNOWLEDGE BASE my_knowledge_base
       model = mindsdb.embedding_model;

-- Insert data into the knowledge base
    INSERT INTO my_knowledge_base (content)
    VALUES ("I really enjoyed reading about your experiences and lessons learned as a developer. It's clear that you have a passion for this field and a dedication to constantly improving your skills. Keep on coding!");

--  Create a skill for sentiment analysis using the knowledge base
    CREATE SKILL sentiment_analysis_skill
        type = 'knowledge_base',
        source = 'my_knowledge_base',
        description = 'Sentiment Analysis';

Above code structure introduces a knowledge base (my_knowledge_base) and a skill (sentiment_analysis_skill) that utilizes the knowledge base. The sentiment analysis model (comment_analyzer) is then associated with the skill in an agent (my_agent).

πŸ›  How We Tackled Challenges:

let's simplify the challenges and how we tackled them:

1. Installation Challenge :

Our first challenge was installing MindsDB because the cloud version was down. Docker and pip install didn't work well due to slow internet and low specs. Seeking help in the MindsDB community Discord, we got instant support. Though initial suggestions didn't work, a community member advised installing MindsDB through source by cloning the repo. This method worked for both Linux and Windows systems, overcoming the installation challenge.

This picture captures the moment when Tarun, a helpful community member, assisted us in solving the installation challenge. Although we couldn't capture our direct Zoom meeting with him, this image symbolizes the support and guidance he and other community member provided during the troubleshooting process.

This is the screenshot of slack which shows how tarun(one of the community member if Mindsdb) helps us)

2. Using GraphQL hashnode API :

MindsDB supported YouTube comments but not Hashnode. While exploring contributing to MindsDB for Hashnode integration, we decided to use Hashnode's GraphQL API due to time constraints. The GraphQL API was new to us, so we sought help in the Hashnode Discord channel. They provided us with a GraphQL query to fetch data, resolving our issue with using the Hashnode GraphQL API.

In this Picture, Community member of Hashnode is helping us to use GraphQL hashnode Api

3. Processing comments in batch

Initially, processing comments one by one was time-consuming, leading to timeouts with the GPT-3.5 turbo model. We requested and received access to the GPT-4 model, but the problem persisted. To enhance efficiency, we decided to process comments in batches of 5. Designing the perfect prompt was crucial, and after testing in the MindsDB GUI editor, we created an effective prompt. This reduced processing time significantly, allowing us to analyze 100 to 200 comments in just 5-6 seconds.

πŸŽ₯ Video Crafting and Presentation:

After a month of hard work on our app Apexa, we decided to push our limit and create an awesome video presentation. My friend and I didn't have powerful laptops, but luckily, our friends did, and also had great video editing skills. He even suggested a cool idea for the first part of the video, which you can check out on our YouTube channel.

We borrowed a tripod and a good mobile phone for video recording. Planning our presentation, we created simple scripts for the video. Since my friend and I lived in the same city, we met up at his house to record. It wasn't all smooth sailing; we had to do several re-shoots because our screen recorder crashed and didn't capture high-quality footage. After searching for another recorder, we finally got it right. It took us two days to record the video, and then we sent the clips to our friend Bishesh, who worked his magic to edit the video into a simple and creative masterpiece. πŸš€

Now, the awesome video is ready for everyone to watch!

Let's view the some snapshot's during our video making:

This picture captures us during a late-night reshoot for our video. Behind those smiles, there's a bit of sadness due to the frustration caused by a crash.

πŸŽ‰ Conclusion:

Overall the hackathon was a great experience for learning. We got to learn about Minds-db, generating models, training models, got a kick start on handling GraphQL API and learned some better ways to google. And most important of all, we developed a new skill of being patient when our code doesn't work and we don't get any solutions at all. Taking help from the community on discord, Slack and shaping the app. The whole experience was great, and if you haven't tried a hackathon yet, give it a shot now!
