LSTM to Transformers
Transformer models has become the go-to model in most of the NLP tasks. Many transformer-based models like BERT, ROBERTa, GPT series, etc are considered as the state-of-the-art models in NLP. While NLP is overwhelming with all these models, Transformers are gaining popularity in Computer vision also. Transformers are now used for recognizing and constructing images, […]
Transformer Based Models
Transformer models have achieved a significant milestone in the field of NLP. Not only in the field of NLP, but also in Computer Vision, we can see Transformer models outperforming all the so-called state-of-the-art models. Transformers have been proven to improve long-term dependencies and can be used to leverage the technique called Transfer learning, which […]
