Scientists, engineers and the like are a strange lot. Unperturbed by societal norms,
they direct their energies to finding better alternatives to existing theories and concocting
solutions to unsolved problems. Driven by an insatiable curiosity, they record
their observations and crunch the numbers. This tome is about the science of crunching.
It’s about digging out something of value from the detritus that others tend to
leave behind. The described approaches involve constructing models to process the
We present a pointwise approach to Japanese morphological analysis (MA) that ignores structure information during learning and tagging. Despite the lack of structure, it is able to outperform the current state-of-the-art structured approach for Japanese MA, and achieves accuracy similar to that of structured predictors using the same feature set. We also ﬁnd that the method is both robust to outof-domain data, and can be easily adapted through the use of a combination of partial annotation and active learning. ...
This work presents an agenda-based approach to improve the robustness of the dialog manager by using dialog examples and n-best recognition hypotheses. This approach supports n-best hypotheses in the dialog manager and keeps track of the dialog state using a discourse interpretation algorithm with the agenda graph and focus stack. Given the agenda graph and n-best hypotheses, the system can predict the next system actions to maximize multi-level score functions. To evaluate the proposed method, a spoken dialog system for a building guidance robot was developed.
be used for efficiency by providing a best-first search heuristic to order the parsing agenda. This paper proposes an agenda-based probabilistic chart parsing algorithm which is both robust and efficient. The algorithm, 7)icky 1, is considered robust because it will potentially generate all constituents produced by a pure bottom-up parser and rank these constituents by likelihood. The efficiency of the algorithm is achieved through a technique called probabilistic prediction, which helps the algorithm avoid worst-case behavior. ...
Bioinformatics is at a crossroads. We work in a field that is changing
every day, increasingly moving from specific solutions created by single
researchers working alone or in small groups to larger, often
geographically dispersed programs enabled by collaborative computing
and open software. This book represents an important development, giving
the reader an opportunity to discover how the use of open and reusable
Java code can solve large bioinformatics problems in a software
engineered and robust way.
We choose the kinesins to illustrate similarities and
diﬀerences between protein family databases. Kinesin
and its relatives are motor proteins that utilize ATP
hydrolysis to move along microtubules in eukaryotic cells.
The motor portion of a kinesin is structurally very similar
to that of the myosin motor, which moves along actin
ﬁlaments, although no sequence similarity is evident
between them. This is an example of likely divergence
from an ancestral fold that is beyond current sequence-
based comparison methods to detect.
Furniture is a
ubiquitous object, i.e., it can be found everywhere at home or the office, and it can
integrate and hide the sensors of a network. This work addresses the lack of an exhaustive
study of the effect of furniture on signal losses. In addition an easy-to-use tool for
estimating the robustness of the communication channel among the sensor nodes and
gateways is proposed. Specifically, the losses in a sensor network signal due to the
materials found within the communication link are evaluated.
United Nations agencies and global funding initiatives (such as the
Global Fund and PEPFAR) have fundamental responsibility for realizing
the potential of comprehensive services to prevent vertical transmission
of HIV. These entities must be funders, coordinators, technical advisors
and global champions. The research in the six countries covered in this
report suggests that although several global entities have made important
contributions to delivery of comprehensive services, their individual
impacts have been constrained by insufficient linkages and collaboration.
'Accessible' means that not all the available resource
can be used because of physical constraints (a
large part of the aquifers, flood water greater than
needed for reservoirs replenishment), inappropriate
location or timeliness, inappropriate quality, and
because part of the annual service flow has to be left
to the ecosystem for its own needs.
It is promising, however, that a a majority of male and female respondents perceive social media as an enabler for women’s
empowerment. This is coupled with the robust growth of social media usage among youth in the Arab region. If lessons are
to be drawn from youth utilization of social media during the recent popular movements in the Arab world, then in light of
the growing sense of empowerment today, the strong positive perceptions shown in our survey suggest that social media
can continue to play an important role in empowering Arab women in the future. However, this will only...
To my knowledge, this paper is the first to find evidence that news media
content can predict movements in broad indicators of stock market activity.
Using principal components analysis, I construct a simple measure of media
pessimismfromthe content of theWSJ column. I then estimate the intertempo-
ral links between this measure of media pessimism and the stock market using
basic vector autoregressions (VARs). First and foremost, I find that high lev-
els of media pessimism robustly predict downward pressure on market prices,
followed by a reversion to fundamentals.
This volume brings about the contemporary results in the field of discrete-time systems. It covers papers written on the topics of robust control, nonlinear systems and recent applications. Although the technical views are different, they all geared towards focusing on the up-to-date knowledge gain by the researchers and providing effective developments along the systems and control arena. Each topic has a detailed discussions and suggestions for future perusal by interested investigators.
Consider the family of sensor routing protocols where each sensor communicates either directly or indirectly
with a base station. In turn the base station correlates and aggregates information from each sensor. Accordingly,
the base station will need to verify the authenticity of the sensor, the integrity of the communication and ascertain
that it is not a replay of an earlier communication. Recall the assumption that the base station is computationally
robust and secure. In our protocol each sensor j shares a unique 64 bit Key Key , with the base station.

mpulsive noise consists of relatively short duration “on/off” noise pulses, caused by a variety of sources, such as switching noise, adverse channel environments in a communication system, dropouts or surface degradation of audio recordings, clicks from computer keyboards, etc.
The goal of Defensive Programming is to produce resilient code that responds gracefully to the unexpected. To the SQL Server programmer, this means T-SQL code that behaves consistently and predictably in cases of unexpected usage, doesn't break under concurrent loads, and survives predictable changes to database schemas and settings. Inside this book, you will find dozens of practical, defensive programming techniques that will improve the quality of your T-SQL code and increase its resilience and robustness. ...
An estimated 3 to 4 million Californians are predicted
to remain uninsured in 2019. Of those, slightly more
than 1 million will not be eligible for coverage options
under the ACA due to immigration status. Another
800,000 to 1.2 million will be eligible for Medi-Cal or
Healthy Families. If and when they seek care, they will
have the ability to enroll in coverage. Robust outreach
and education can also decrease the number of uninsured
who are not aware of coverage opportunities and
are therefore less likely to seek care or receive preventive
We pose the development of cognitively plausible models of human language processing as a challenge for computational linguistics. Existing models can only deal with isolated phenomena (e.g., garden paths) on small, speciﬁcally selected data sets. The challenge is to build models that integrate multiple aspects of human language processing at the syntactic, semantic, and discourse level. Like human language processing, these models should be incremental, predictive, broad coverage, and robust to noise. ...
In this paper we discuss the use of discourse context in spoken dialogue systems and argue that the knowledge of the domain, modelled with the help of dialogue topics is important in maintaining robustness of the system and improving recognition accuracy of spoken utterances. We propose a topic model which consists of a domain model, structured into a topic tree, and the Predict-Support algorithm which assigns topics to utterances on the basis of the topic transitions described in the topic tree and the words recognized in the input utterance. ...
