Driver2vec: Driver Identification from Automotive Data

no code implementations10 Feb 2021 Jingbo Yang, Ruge Zhao, Meixian Zhu, David Hallac, Jaka Sodnik, Jure Leskovec

In this paper, we develop a deep learning architecture (Driver2vec) to map a short interval of driving data into an embedding space that represents the driver's behavior to assist in driver identification.

MASA: Motif-Aware State Assignment in Noisy Time Series Data

1 code implementation6 Sep 2018 Saachi Jain, David Hallac, Rok Sosic, Jure Leskovec

Such data can be interpreted as a sequence of states, where each state represents a prototype of system behavior.

Drive2Vec: Multiscale State-Space Embedding of Vehicular Sensor Data

no code implementations12 Jun 2018 David Hallac, Suvrat Bhooshan, Michael Chen, Kacem Abida, Rok Sosic, Jure Leskovec

With automobiles becoming increasingly reliant on sensors to perform various driving tasks, it is important to encode the relevant CAN bus sensor data in a way that captures the general state of the vehicle in a compact form.

Spectral Graph Wavelets for Structural Role Similarity in Networks

no code implementations ICLR 2018 Claire Donnat, Marinka Zitnik, David Hallac, Jure Leskovec

Nodes residing in different parts of a graph can have similar structural roles within their local network topology.

Learning Structural Node Embeddings Via Diffusion Wavelets

1 code implementation KDD 2018 Claire Donnat, Marinka Zitnik, David Hallac, Jure Leskovec

Nodes residing in different parts of a graph can have similar structural roles within their local network topology.

Data-Driven Model Predictive Control of Autonomous Mobility-on-Demand Systems

no code implementations20 Sep 2017 Ramon Iglesias, Federico Rossi, Kevin Wang, David Hallac, Jure Leskovec, Marco Pavone

The goal of this paper is to present an end-to-end, data-driven framework to control Autonomous Mobility-on-Demand systems (AMoD, i. e. fleets of self-driving vehicles).

Toeplitz Inverse Covariance-Based Clustering of Multivariate Time Series Data

no code implementations10 Jun 2017 David Hallac, Sagar Vare, Stephen Boyd, Jure Leskovec

We derive closed-form solutions to efficiently solve the two resulting subproblems in a scalable way, through dynamic programming and the alternating direction method of multipliers (ADMM), respectively.

Driver Identification Using Automobile Sensor Data from a Single Turn

no code implementations9 Jun 2017 David Hallac, Abhijit Sharang, Rainer Stahlmann, Andreas Lamprecht, Markus Huber, Martin Roehder, Rok Sosic, Jure Leskovec

In this paper, we propose a method to predict, from sensor data collected at a single turn, the identity of a driver out of a given set of individuals.

Network Inference via the Time-Varying Graphical Lasso

1 code implementation6 Mar 2017 David Hallac, Youngsuk Park, Stephen Boyd, Jure Leskovec

Many important problems can be modeled as a system of interconnected entities, where each entity is recording time-dependent observations or measurements.

Greedy Gaussian Segmentation of Multivariate Time Series

1 code implementation24 Oct 2016 David Hallac, Peter Nystrup, Stephen Boyd

We consider the problem of breaking a multivariate (vector) time series into segments over which the data is well explained as independent samples from a Gaussian distribution.
