ehsanaghaei / SecureBERT_Plus

SecureBERT+

This model represents an improved version of the SecureBERT model, trained on a corpus eight times larger than its predecessor, leveraging the computational power of 8xA100 GPUs. This version, known as SecureBERT+, brings forth an average improvment of 9% in the performance of the Masked Language Model (MLM) task. This advancement signifies a substantial stride towards achieving heightened proficiency in language understanding and representation learning within the cybersecurity domain.

SecureBERT is a domain-specific language model based on RoBERTa which is trained on a huge amount of cybersecurity data and fine-tuned/tweaked to understand/represent cybersecurity textual data.
