BERT, which stands for Bidirectional Encoder Representations from Transformers, is a state-of-the-art natural language processing model in the field of deep learning. It's based on the Transformer architecture and is pre-trained on a large corpus of text data, enabling it to understand context and semantics in a bidirectional manner, which means it considers both the left and right context of a word when processing text. BERT has significantly improved the performance of various NLP tasks, such as text classification, question-answering, and sentiment analysis, and has become a foundational model for many NLP applications. Researchers and developers often fine-tune BERT for specific language understanding tasks, making it a versatile tool for a wide range of natural language processing challenges.- PaLI-3 Vision Language Models Smaller, Faster, Stronger (15 Oct 2023)
This is reading note for PaLI-3 Vision Language Models: Smaller, Faster, Stronger. This paper proposes to use image-text-matching to replace contrast loss. The experiment indicates this method is especially effective in relatively small models.
- Align before Fuse Vision and Language Representation Learning with Momentum Distillation (11 Oct 2023)
This is my reading note for Align before Fuse: Vision and Language Representation Learning with Momentum Distillation. The paper proposes a multi modality model which is trained base on contrast loss, mask language modeling and image-text match. To handle noisy pairs of text and image, it track moving average of model and distill to the final model.
- RoBERTa A Robustly Optimized BERT Pretraining Approach (07 Oct 2023)
This is my reading note for RoBERTa: A Robustly Optimized BERT Pretraining Approach. This paper revisits the design choice of BERT. It provides that 1) adding more data; 2) using larger batch size; 3) training for more iterations could significantly improves the performance. In addition, using longer sentence/context could also improve performance and next sentence prediction is no longer useful.
- MaMMUT A Simple Architecture for Joint Learning for MultiModal Tasks (24 Sep 2023)
This is my reading note for MaMMUT: A Simple Architecture for Joint Learning for MultiModal Tasks. The paper proposes an efficient multi modality model. it proposes to unify generative loss (masked language modeling) and contrast loss via a two pass training process. One pass is for generate loss which utilizes casual attention model in text decoder and the other pass is bidirectional text decoding. The order of two passes are shuffled during the training.

- CoCa Contrastive Captioners are Image-Text Foundation Models (31 Jul 2023)
This is my reading note for CoCa: Contrastive Captioners are Image-Text Foundation Models. The paper proposes a multi modality model, especially it models the problem as image caption as well as text alignment problem. The model contains three component: a vision encoder, a text decoder (which generates text embedding ) and a multi modality decoder , which generate caption given image and text embedding.
- FLAVA A Foundational Language And Vision Alignment Model (30 Jul 2023)
This is my reading note for FLAVA: A Foundational Language And Vision Alignment Model. This paper proposes a multi modality model. Especially, the model not only work across modality, but also on each modality and joint modality. To do that, it contains loss functions for both within modality but also across modality. It also proposes to use the same architecture for vision encoder, Text encoder as well as multi -modality encoder.
