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.

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.

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.

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.
