NeoAgDT: optimization of personal neoantigen vaccine composition by digital twin simulation of a cancer cell population
Anja Moesch, Filippo Grazioli, Pierre Machart, Brandon Malone
Bioinformatics, 2024
paper  /  code

NeoAgDT is a framework for optimizing personalized neoantigen-based cancer vaccines. It is a two-step approach consisting of: (i) simulating individual cancer cells to create a digital twin of the patient’s tumor cell population and (ii) optimizing the vaccine composition by integer linear programming based on this digital twin.

Are you a robot? Detecting Autonomous Vehicles from Behavior Analysis

Can we detect autonomous vehicles from their behaviors in scenarios in which they share the road with human-driven ones? For this work, we created the NexusStreet dataset and made it publicly available.

paper  /  bibtex

The interaction between T cell receptors (TCRs) and peptide antigens is critical for human immune responses. Designing antigen-specific TCRs represents an important step in adoptive immunotherapy. We propose a disentangled autoencoder, which can act as generative model for optimized TCR sequences. Optimized TCR sequences present enhanced binding affinity to a given peptide and preserve the backbone of a template TCR.

paper  /  bibtex  /  code

A multi-sequence variational method for binding prediction between T-cell receptors (TCRs) and peptides presented on cells. We present a multi-sequence generalization of Variational Information Bottleneck (VIB) (Alemi et al., 2016) and call it Attentive Variational Information Bottleneck (AVIB). AVIB leverages multi-head self-attention (Vaswani et al., 2017) to implicitly approximate a posterior distribution over latent encodings conditioned on multiple input sequences.

On TCR binding predictors failing to generalize to unseen peptides

Frontiers in Immunology, 2022
paper  /  bibtex  /  code  /  dataset

Here, we investigate the generalization capabilities of current deep-learning-based TCR binding predictors, i.e. models that predict the interaction of T cell receptors (TCRs) and peptide-MHC complexes presented on cells. We create a dataset, named TChard, including samples from IEDB, VDJdb, McPAS-TCR, and the MIRA set, as well as negative samples from both randomization and 10X Genomics assays. Our results show that modern deep learning methods fail to generalize to unseen peptides.

paper  /  bibtex  /  code

A multimodal learning model derived from the theory of the information bottleneck. By looking at a patient's gut microbiome, we predict if they are affected by a certain disease.

Face Verification from Depth using Privileged Information

paper  /  bibtex  /  video

A deep Siamese architecture for depth-based face verification. Leveraging privileged information learning, the model relies only on depth images, hallucinating the color information.

A model of control distribution between users and the automated systems. Objective driving data and eye-tracking parameters are used to estimate the model’s accuracy.

Simulation Framework for Executing Component and Connector Models of Self-Driving Vehicles
Filippo Grazioli, Evgeny Kusmenko, Alexander Roth, Bernhard Rumpe, Michael von Wenckstern
International Conference on Model Driven Engineering Languages and Systems (MODELS), 2017
paper  /  bibtex  /  video

A simulator that combines the benefits of both high-level and low-level simulators to execute component and connector models. The simulator allows to include new sensors, actuators and control systems.
