2022年8月17日 · 本示例演示了如何使用 Bryan Lim 等人在 Temporal Fusion Transformers (TFT) for Interpretable Multi-horizon Time Series Forecasting 中提出的门控残差网络（GRN）和变量选择网络（VSN）进行结构化数据分类。GRN 为模型提供了灵活性，只在需要时才进行非线性处理。

This example demonstrates the use of Gated Residual Networks (GRN) and Variable Selection Networks (VSN), proposed by Bryan Lim et al. in Temporal Fusion Transformers (TFT) for Interpretable Multi-horizon Time Series Forecasting, for structured data classification. GRNs give the flexibility to the model to apply non-linear processing only where ...

2021年2月10日 · 变量选择网络 (VSN) 的工作原理如下. 对每个特征单独应用 GRN。 对所有特征的串联应用 GRN，然后使用 softmax 生成特征权重。 生成各个 GRN 输出的加权和。 请注意，VSN 的输出是 [batch_size, encoding_size]，与输入特征的数量无关。

2021年2月10日 · 此範例示範如何使用 Bryan Lim 等人於 Temporal Fusion Transformers (TFT) for Interpretable Multi-horizon Time Series Forecasting 中提出的門控殘差網路 (Gated Residual Networks, GRN) 和變數選擇網路 (Variable Selection Networks, VSN) 進行結構化資料分類。GRN 使模型能夠靈活地僅在需要時應用非線性 ...

2022年4月11日 · 网上的方法包括permutation importance, null importance, 随机对特征进行mask等方法，本文要介绍的是牛津大学和谷歌提出的基于Gated Residual Networks (GRN) and Variable Selection Networks (VSN)的特征重要性计算方法。

GRNs give the flexibility to the model to apply non-linear processing only where needed. VSNs allow the model to softly remove any unnecessary noisy inputs which could negatively impact performance. Together, those techniques help improving the learning capacity of deep neural network models.

2023年7月14日 · 文章介绍了GRM，一种基于AdaptiveTokenDivision的广义关系建模方法，用于Transformer跟踪。 它改进了OSTrack，通过动态地将搜索令牌划分为目标、背景和模板类别，以优化模板与搜索区域的交互，同时使用Gumbel-Softmax解决不可微问题。

**Variable Selection Networks (VSN)**: help in carefully selecting the most important features from the input and getting rid of any unnecessary noisy inputs which could harm the model's performance. - First, it applies a Gated Residual Network (GRN) to each feature individually.

Gated Residual Networks (GRN): consists of skip connections and gating layers that facilitate information flow efficiently. They have the flexibility to apply non-linear processing only where needed. GRNs make use of Gated Linear Units (or GLUs) to suppress the input that are not relevant for a given task.
