The company states that text classification models play a role, in systems like Gmail, YouTube and Google Play.

They help identify content like phishing attacks, comments and scams. However spammers constantly try to outsmart these classifiers by using text manipulations.

This makes it challenging for machine learning models to accurately classify texts. As an example attackers have employed tactics, like homoglyphs, invisible characters and keyword stuffing to bypass Google’s security measures.

How Can RETVec Improve Gmail’s Spam Filters?

Over the years Google has extensively utilized RETVec to evaluate its effectiveness. Has observed significant benefits in terms of security and anti abuse measures.

As part of this effort the company replaced Gmails text vectorizer with RETVec leading to a 38% improvement in spam detection and a reduction of false positives, by 19.4%.

Furthermore when using RETVec the models power consumption was significantly reduced by 83%.

An important advantage is that RETVec doesn’t require any text preprocessing and can work seamlessly with all languages and UTF 8 characters.

This makes it an ideal choice, for scenarios like on device usage, online applications and extensive text classification tasks.

Google states that models trained with RETVec exhibit inference speeds due to its representation.

These smaller models not reduce costs but also decrease latency, which is crucial for large scale applications and on device models.

Additionally the RETVec trained models can be easily converted to TFLite format for utilization, on devices and edge computing platforms. The open source model can be found on Github.
