AI-Powered Features in Lefty: A Brief Timeline

At the Beginning: Computer Vision for Visual Analysis

Lefty began its AI journey by using Convolutional Neural Networks (CNNs) to analyze influencer photos. This enabled accurate detection of:

Categories — Recognizing relevant themes and topics.

Gender and Age — Identifying demographics for both influencers and their audiences.

2017: Statistical Models for Audience Quality & Engagement

In 2017, our AI models evolved to estimate key performance metrics & audience insights of influencers:

Detecting bots, fake accounts, and inactive followers.

Assessing audience quality and improving targeting accuracy.

Predicting post performance to optimize campaign outcomes.

With the integration of BERT (Bidirectional Encoder Representations from Transformers), we expanded our capabilities to text-based analysis:

Enhancing detection of interests and categories.

Identifying geolocation for both influencers and their followers.

2022: Large Language Models (LLMs) for Advanced Classification

LLMs brought a new level of precision to Lefty’s AI, giving us the ability to:

Detect sensitive topics in influencer content to ensure brand safety.

Refine influencer classification for client-defined custom categories.
