An Empirical Evaluation of Deep Learning on Highway Driving
Numerous groups have applied a variety of deep learning techniques to
computer vision problems in highway perception scenarios. In this paper, we
presented a number of empirical evaluations of recent deep learning advances.
Computer vision, combined with deep learning, has the potential to bring about
a relatively inexpensive, robust solution to autonomous driving. To prepare
deep learning for industry uptake and practical applications, neural networks
will require large data sets that represent all possible driving environments
and scenarios. We collect a large data set of highway data and apply deep
learning and computer vision algorithms to problems such as car and lane
detection. We show how existing convolutional neural networks (CNNs) can be
used to perform lane and vehicle detection while running at frame rates
required for a real-time system. Our results lend credence to the hypothesis
that deep learning holds promise for autonomous driving.Comment: Added a video for lane detectio
MultiNet: Multi-Modal Multi-Task Learning for Autonomous Driving
Autonomous driving requires operation in different behavioral modes ranging
from lane following and intersection crossing to turning and stopping. However,
most existing deep learning approaches to autonomous driving do not consider
the behavioral mode in the training strategy. This paper describes a technique
for learning multiple distinct behavioral modes in a single deep neural network
through the use of multi-modal multi-task learning. We study the effectiveness
of this approach, denoted MultiNet, using self-driving model cars for driving
in unstructured environments such as sidewalks and unpaved roads. Using labeled
data from over one hundred hours of driving our fleet of 1/10th scale model
cars, we trained different neural networks to predict the steering angle and
driving speed of the vehicle in different behavioral modes. We show that in
each case, MultiNet networks outperform networks trained on individual modes
while using a fraction of the total number of parameters.Comment: Published in IEEE WACV 201
