We developed an AI Document Navigator (AIDN) to help a client efficiently retrieve information from large sets of PDFs and JSON files. Our goal was to enhance document access, making it faster and more accurate with advanced AI technologies. A key challenge was handling large documents without slowing down. We optimized document splitting and retrieval processes for quick responses. We also created a context-aware retriever for more relevant information. We used OpenAI's GPT-4 for language processing, FAISS for vector storage, and implemented recursive text splitting for document chunking. We also employed robust security measures to manage environment variables.

To calculate the Customer Lifetime Value (LTV) for a U.S. firm, we first analyzed historical data to determine the Average Purchase Value (APV). This involved dividing the firm's total revenue over a specific period by the number of purchases in that period. Next, we calculated the Average Purchase Frequency Rate (APFR) by dividing the total number of purchases by the number of unique customers. Multiplying APV with APFR gave us the Customer Value. Then, we estimated the Average Customer Lifespan (ACL) by analyzing the duration of customer relationships. The LTV was calculated by multiplying Customer Value with ACL. This process provided insight into how much revenue a customer would bring over their relationship with the firm. By understanding LTV, the company can make informed decisions on customer acquisition and retention strategies.

We analyzed automotive sales data spanning from April 2007 to May 2023 across GCC countries such as Saudi Arabia, Kuwait, the United Arab Emirates, Qatar, Bahrain, and Oman. Through extensive visualization, we delved into the sales performance of various manufacturers and car segments. Our findings uncovered compelling trends and patterns in the GCC automotive industry over sixteen years. Notably, certain manufacturers consistently dominated the market, while others experienced sales fluctuations. These insights offer valuable guidance for industry stakeholders and policymakers, aiding in informed decision-making and strategic planning for the future of the automotive market in the GCC region.
