Experience
Automatic Description Generation From Images
The apartment photo database includes the price of the apartment, floor, latitude, longitude, nearby places, and whether it has parking. First, we had to eliminate duplicate photos from one apartment, so we would not detect items repeatedly. In the second step, the photos are then classified into room types. In the third step, count the number of bedrooms, baths, and other rooms, as well as detect the amenities. The fourth step is to create a dataset for description generation, and last but not least, to generate the description from the transformer model.
ChatGPT Powered Voice-based Customer Support
The system's functionality enables customers to call a business's Twilio phone number and ask a query, which ChatGPT then processes to provide personalized responses based on the customer's input. The ChatGPT model has been trained to understand and respond to a wide range of customer queries.
