![]() In the paper presented in this article, we experimented with deep learning models on tabular data by introducing a simple baseline and comparing it with existing methods. In general, FT-Transformer requires more time for training, which is especially noticeable on datasets with a large number of features (YA) the large computational cost of FT-Transformer is an important issue to be improved in the future. The comparison of each method in this synthesis task is as follows.Īs shown in the figure, the performance of ResNet deteriorates significantly in GBDT-oriented settings, while FT-Transformer shows generally good results, revealing the universality of FT-Transformer.įinally, a comparison of the learning time between ResNet and FT-Transformer is shown below. This synthetic task is considered to be more suitable for GBDT when $\alpha$ is large, and more suitable for deep learning methods when $\alpha$ is small. ![]() The Feature Tokenizer module converts the input $x$ into an embedding $T \in R^(x)$ Then, the prediction is made based on the representation corresponding to the last token. The whole process is as follows: first, the input $x$ is converted into an embedding $T$ by the Feature Tokenizer, and then $T0$, to which a token is added, is passed through the Transformer. The rough structure is shown in the following figure. Next, we introduce the FT-Transformer (Feature Tokenizer Transformer), which is a modification of the Transformer architecture that has been used successfully for various tasks including natural language processing, for tabular data. ResNetBlock introduces a skip connection similar to the existing ResNet. $Prediction(x) = Linear (ReLU (BatchNorm (x)))$ $ResNetBlock(x) = x + Dropout(Linear(Dropout(ReLU(Linear(BatchNorm(x))))))$ This is represented by the following equation Next, we introduce a simple baseline based on ResNet, which is mainly used in computer vision tasks and other applications. $MLPBlock(x) = Dropout(ReLU(Linear(x)))$ ResNet MLP(Multi Layer Perceptron) is expressed by the following equation. A Model for Tabular Data Problemsįirst, we introduce our model for conducting performance comparison experiments on tabular data problems. In the paper presented in this article, we have introduced a simple baseline method for tabular data and a diverse set of tasks to provide a detailed examination of deep learning methods on tabular data. Hence, questions such as the effectiveness of deep learning methods on tabular data and which method is better than GBDT or deep learning methods remain unclear. However, in the domain of tabular data, existing deep learning methods have not been sufficiently compared, partly because there are no established benchmarks (such as ImageNet for image recognition or GLUE for natural language processing). Gradient Boosting Decision Trees (GBDTs) are well known as effective methods for tabular data, but there is also a lot of research on using deep learning for tabular data. ![]() The images used in this article are from the paper, the introductory slides, or were created based on them.
