A practical use case from your great job for the spanish language
Model
In this project, I developed an efficient and fast user intent classification system by leveraging an ensemble of logistic regression, SVM, and k-NN classifiers. The model uses text embeddings from the jinaai/jina-embeddings-v2-base-es model to achieve high accuracy while being significantly more resource-efficient compared to large language models (LLMs).
Motivation
Detecting user intent is crucial for retrieve-augmented generation (RAG) pipelines in conversational AI. These pipelines often require multiple calls to LLMs and sophisticated prompt engineering, which can be both time-consuming and costly. Our approach seeks to drastically reduce the time and number of calls to LLMs, providing a fast and cost-effective solution without compromising accuracy. This model focuses on classifying requests and questions in Spanish, supporting intents like censorship, others, lead, contact, directions, meet, negation, affirmation, and casual chat.
