The client's needs

The client envisioned a recommendation system powered by LLMs to deliver personalized product suggestions based on customer demographics, needs, and global trends. They saw an opportunity to automate business offers in complex environments. Dataforest took this vision from prototype to a fully functional web app with sophisticated recommendation and forecasting tools.

Challenges & solutions

Challenge

Develop a solution capable of handling an inventory scaled to over 100,000 products.

Solution

To address this complexity, we integrated the LLM with a Qdrant vector database and advanced ML models, including classification and clustering, further optimized results, providing precise recommendations at scale.

Challenge

Ensure the solution delivers results with high accuracy.

Solution

To deliver high accuracy for business offers generation, we integrated Qdrant vector DB with an LLM (Claude Sonnet 3) to perform retrieval-augmented generation (RAG), ensuring the system retrieves and contextualizes relevant data points before generating personalized product recommendations.

Engineered prompts tailored to yield highly accurate, contextually relevant recommendations and enhance the reasoning capabilities of the LLM, utilizing state of the art prompting techniques such as Chain-of-Thought (CoT) and Meta prompting.

Challenge

Achieve high efficiency and rapid results in generating new opportunities.

Solution

Our solution harnesses the power of Qdrant vector DB and advanced prompt engineering to deliver swift, precise filtering—driving exceptional speed and efficiency in opportunity generation.

Challenge

Delivering highly personalized, timely recommendations in an intuitive manner. 

Solution

Developed a text2query system that transforms natural language product and customer descriptions into a custom ElasticSearch-like query format, enabling users to intuitively filter products and customer profiles for enhanced interaction flexibility.

Incorporated information on global events via Web Search services, allowing the recommendation engine to adjust suggestions based on relevant and impactful current events.

Leveraged the LLM to dynamically create and populate nodes within a knowledge graph, enabling a structured and interconnected representation of customer preferences, product information, and interactions, further enhancing recommendation quality.
