TabDPT: Scaling Tabular Foundation Models

Installation

To run TabDPT, install the following packages:

• pytorch
• numpy
• scikit-learn
• faiss

You need to also download the weights below.

Example Usage 1

from sklearn.metrics import accuracy_score
from sklearn.datasets import load_breast_cancer
from sklearn.model_selection import train_test_split
from tabdpt import TabDPTClassifier

X, y = load_breast_cancer(return_X_y=True)
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.33, random_state=42)

model = TabDPTClassifier(path='checkpoints/tabdpt_76M.ckpt')
model.fit(X_train, y_train)
y_pred = model.predict(X_test, temperature=0.8, context_size=1024)
print(accuracy_score(y_test, y_pred))

Example Usage 2

from sklearn.metrics import accuracy_score
from sklearn.datasets import fetch_california_housing
from sklearn.model_selection import train_test_split
from sklearn.metrics import r2_score
from tabdpt import TabDPTRegressor

X, y = fetch_california_housing(return_X_y=True)
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.33, random_state=42)

model = TabDPTRegressor(path='checkpoints/tabdpt_76M.ckpt')
model.fit(X_train, y_train)
y_pred = model.predict(X_test, context_size=1024)
print(r2_score(y_test, y_pred))
