Ananta R. Bhattarai

Hi, I am Ananta. I hold a Master's degree in Computer Science from TU Munich. I did my Master's thesis at the Visual Computing Lab supervised by Prof. Matthias Niessner and Artem Sevastopolsky. Alongside my Master's studies, I was fortunate to work with Dr. Michael Lebacher and Prof. Florian Buettner on Explainable AI at Siemens AG.

Previously, I completed my Bachelor's degree in Computer Science at Jacobs University Bremen. During my Bachelor's, I spent a term abroad at Carnegie Mellon University, where I did independent research under the supervision of Prof. Ruslan Salakhutdinov.

I'm interested in working at the intersection of 3D computer vision, computer graphics, and machine learning. My Master's thesis focused on the 3D GAN inversion for 3D reconstruction and novel view synthesis from a single 2D image.

    TriPlaneNet: An Encoder for EG3D Inversion
    Ananta R. Bhattarai, Matthias Niessner, Artem Sevastopolsky
    WACV, 2024
    project page / video / arXiv

    EG3D is a powerful {z, camera}->image generative model, but inverting EG3D (finding a corresponding z for a given image) is not always trivial. We propose a fully-convolutional encoder for EG3D based on the observation that predicting both z code and tri-planes is beneficial. TriPlaneNet also works for videos and in real time (check out the Live Demo).

    Towards Scenario-based Safety Validation for Autonomous Trains with Deep Generative Models

    SAFECOMP, 2023
    arXiv

    The framework leverages a conditional Generative Adversarial Network (cGAN) to manipulate the style of a specific category within a given image and compares segmentation maps to verify the model's robustness.

    Combining Programmable Potentials and Neural Networks for Materials Problems

    paper

    By using neural networks as encoding functions, the method automatically learns the quantum-level interaction logic of the system from the data to compute and infer macro-level properties of chemical or material systems.
