+# RoboAdvisor
+
+## What it does and how it works
+1) User gives a stock ticker symbol
+2) The bot queries the Finnhub API and searches for articles, news, Tweets, etc about this company over the last 7 days and downloads them
+3) It then converts the documents into smaller chunks, and uses LLM vector embeddings to convert the documents into a vector index DB, for easy querying
+4) When the user asks (prompts) a question, a vector embedding of the query/prompt is calculated, and a similarity search of this prompt vector is performed against the vector index DB
+5) The top 'k' chunks are retrieved according to the vector similarity search (in this particular case, I am using the FAISS algorithm to perform the similarity search)
+6) The bot then queries the OpenAI GPT-3.5-Turbo API to query on those retrieved chunks, and returns a response.
+
+In short, given a stock ticker symbol, this app uses GPT-3.5 to give investment outlook about it by reading articles, tweets and news about that company

+## Steps to install Ta-Lib in Linux
+
+```
+wget http://prdownloads.sourceforge.net/ta-lib/ta-lib-0.4.0-src.tar.gz
+tar -xzf ta-lib-0.4.0-src.tar.gz
+cd ta-lib/
+./configure --prefix=/usr
+make
+sudo make install
+pip install ta-lib
+```

+
+## Steps for Kuberenetes deplolyment is GCP
+
+1. docker build -t robo_advisor .
+2. docker tag robo_advisor gcr.io/asom-barta-qna-bot/robo_advisor
+3. docker push gcr.io/asom-barta-qna-bot/robo_advisor
+4. Go to "container registry" and verify that the docker image is present
+5. Go to 'Kubernetes Engine' in the Google Cloud Console and create a new Kubernetes cluster in Autopilot mode. Select a location in Asia. Wait for the k8s cluster to be created.
+6. Once the cluster is created, create a deployment. Select the docker image from container registry, give a suitable name to the deployment.
+7. Click on "Expose deployment as a new service", and set the port as 7860 (since the default port used by the Gradio app is 7860), and deploy.
+
+It may appear like this at first:

+
+But it just needs some time to allocate the resources. Check back after 10-15 mins, it should be all green and ready.
