Reprinted from Quantum Bit Xiao Xiao from Aofeisi Quantum Bit Report | WeChat Official Account QbitAI What are the differences between Longformer, a model capable of efficiently processing long texts, and BigBird, which is considered an “upgraded version” of the Transformer model? What do the various other variants of the Transformer model (X-former) look like, … Read more
Follow the public account to discover the beauty of CV technology This article is reprinted from Machine Heart, edited by Panda W. Transformers are powerful but not perfect, especially when dealing with long sequences. State Space Models (SSMs) perform quite well on long sequences. Researchers proposed last year that SSMs could replace Transformers, as seen … Read more

Multivariate time series classification (MTSC) has attracted extensive research attention due to its diverse real-world applications. Recently, utilizing Transformers for MTSC has achieved state-of-the-art performance. However, existing … Read more
The Transformer has shown strong capabilities in time series forecasting, capable of describing pairwise dependencies and extracting multi-level representations from sequences. However, researchers have also questioned the effectiveness of Transformer-based predictors. These predictors often embed multiple variables at the same timestamp into indistinguishable channels and attend to these time tokens to capture temporal dependencies. Considering … Read more
Madio.net Mathematics China ///Editor: Only Tulips’ Garden The essence of the Transformer is an Encoder-Decoder structure, as shown in the figure: Before the advent of transformers, most sequence-to-sequence models (Encoder-Decoder) were based on CNNs and RNNs. In this article, we have already introduced the Attention and Self-attention mechanisms, and the Transformer is based on the … Read more
Transformers have brought tremendous advancements to various natural language tasks and have recently begun to penetrate the field of computer vision, starting to show potential in tasks previously dominated by CNNs. A recent study from the University of California, San Diego, and Google Research proposed using visual Transformers to train GANs. To effectively apply this … Read more
Step 1 — Define the Dataset For demonstration purposes, the dataset here contains only three English sentences, using a very small dataset to intuitively perform numerical calculations. In real applications, larger datasets are used to train neural network models, such as ChatGPT, which was trained on data amounting to 570 GB. Our entire dataset contains … Read more
