ALBERT (A Lite BERT) is a lighter and more efficient version of BERT designed to reduce computational complexity and memory usage while maintaining performance.
ALBERT addresses BERT's limitations of parameter redundancy and memory limitation by employing factorized embedding parameterization, cross-layer parameter sharing, and introducing the Sentence Order Prediction (SOP) loss.
ALBERT achieves comparable or superior results to BERT on NLP benchmarks while using significantly fewer parameters, making it suitable for research and real-world applications with memory and computational constraints.
Practical applications of ALBERT include sentiment analysis, question answering (QA), and named entity recognition (NER), benefiting from its speed and memory efficiency.
