text: "We consider an extension of the contextual multi-armed bandit problem, in\r\nwhich,
instead of selecting a single alternative (arm), a learner is supposed\r\nto make
a preselection in the form of a subset of alternatives. More\r\nspecifically,
in each iteration, the learner is presented a set of arms and a\r\ncontext, both
described in terms of feature vectors. The task of the learner is\r\nto preselect
$k$ of these arms, among which a final choice is made in a second\r\nstep. In
our setup, we assume that each arm has a latent (context-dependent)\r\nutility,
and that feedback on a preselection is produced according to a\r\nPlackett-Luce
model. We propose the CPPL algorithm, which is inspired by the\r\nwell-known UCB
algorithm, and evaluate this algorithm on synthetic and real\r\ndata. In particular,
we consider an online algorithm selection scenario, which\r\nserved as a main
motivation of our problem setting. Here, an instance (which\r\ndefines the context)
from a certain problem class (such as SAT) can be solved\r\nby different algorithms
(the arms), but only $k$ of these algorithms can\r\nactually be run."

text: "Algorithm selection (AS) deals with the automatic selection of an algorithm\r\nfrom
a fixed set of candidate algorithms most suitable for a specific instance\r\nof
an algorithmic problem class, where \"suitability\" often refers to an\r\nalgorithm's
runtime. Due to possibly extremely long runtimes of candidate\r\nalgorithms, training
data for algorithm selection models is usually generated\r\nunder time constraints
in the sense that not all algorithms are run to\r\ncompletion on all instances.
Thus, training data usually comprises censored\r\ninformation, as the true runtime
of algorithms timed out remains unknown.\r\nHowever, many standard AS approaches
are not able to handle such information in\r\na proper way. On the other side,
survival analysis (SA) naturally supports\r\ncensored data and offers appropriate
ways to use such data for learning\r\ndistributional models of algorithm runtime,
as we demonstrate in this work. We\r\nleverage such models as a basis of a sophisticated
decision-theoretic approach\r\nto algorithm selection, which we dub Run2Survive.
Moreover, taking advantage of\r\na framework of this kind, we advocate a risk-averse
approach to algorithm\r\nselection, in which the avoidance of a timeout is given
high priority. In an\r\nextensive experimental study with the standard benchmark
ASlib, our approach is\r\nshown to be highly competitive and in many cases even
superior to\r\nstate-of-the-art AS approaches."

text: 'AbstractThe C-type lectin receptor langerin
plays a vital role in the mammalian defense against invading pathogens. Its function
hinges on the affinity to its co-factor Ca2+ which in turn
is regulated by the pH. We studied the structural consequences of pro-tonating
the allosteric pH-sensor histidine H294 by molecular dynamics simulations (total
simulation time: about 120 μs) and Markov models. We discovered a mechanism in
which the signal that the pH has dropped is transferred to the Ca2+-binding
site without transferring the initial proton. Instead, protonation of H294 unlocks
a conformation in which a protonated lysine side-chain forms a hydrogen bond with
a Ca2+-coordinating aspartic acid. This destabilizes Ca2+
in the binding pocket, which we probed by steered molecular dynamics. After Ca2+-release,
the proton is likely transferred to the aspartic acid and stabilized by a dyad
with a nearby glutamic acid, triggering a conformational transition and thus preventing
Ca2+-rebinding.'

text: The three-dimensional (3D) crystal structures of the GAF3 domain of
cyanobacteriochrome Slr1393 (Synechocystis PCC6803)
carrying a phycocyanobilin chromophore could be solved in both 15-Z
dark-adapted state, Pr, λmax = 649 nm, and 15-E
photoproduct, Pg, λmax = 536 nm (resolution, 1.6 and 1.86
Å, respectively). The structural data allowed identifying the large spectral shift
of the Pr-to-Pg conversion as resulting from an out-of-plane rotation of the chromophore’s
peripheral rings and an outward movement of a short helix formed from a formerly
unstructured loop. In addition, a third structure (2.1-Å resolution) starting
from the photoproduct crystals allowed identification of elements that regulate
the absorption maxima. In this peculiar form, generated during X-ray exposition,
protein and chromophore conformation still resemble the photoproduct state, except
for the D-ring already in 15-Z configuration and tilted
out of plane akin the dark state. Due to its formation from the photoproduct,
it might be considered an early conformational change initiating the parental
state-recovering photocycle. The high quality and the distinct features of the
three forms allowed for applying quantum-chemical calculations in the framework
of multiscale modeling to rationalize the absorption maxima changes. A systematic
analysis of the PCB chromophore in the presence and absence of the protein environment
showed that the direct electrostatic effect is negligible on the spectral tuning.
However, the protein forces the outer pyrrole rings of the chromophore to deviate
from coplanarity, which is identified as the dominating factor for the color regulation.

text: In multi-label classification (MLC), each instance is associated with a set
of class labels, in contrast to standard classification where an instance is assigned
a single label. Binary relevance (BR) learning, which reduces a multi-label to
a set of binary classification problems, one per label, is arguably the most straight-forward
approach to MLC. In spite of its simplicity, BR proved to be competitive to more
sophisticated MLC methods, and still achieves state-of-the-art performance for
many loss functions. Somewhat surprisingly, the optimal choice of the base learner
for tackling the binary classification problems has received very little attention
so far. Taking advantage of the label independence assumption inherent to BR,
we propose a label-wise base learner selection method optimizing label-wise macro
averaged performance measures. In an extensive experimental evaluation, we find
that or approach, called LiBRe, can significantly improve generalization performance.

text: In software engineering, the imprecise requirements of a user are transformed
to a formal requirements specification during the requirements elicitation process.
This process is usually guided by requirements engineers interviewing the user.
We want to partially automate this first step of the software engineering process
in order to enable users to specify a desired software system on their own. With
our approach, users are only asked to provide exemplary behavioral descriptions.
The problem of synthesizing a requirements specification from examples can partially
be reduced to the problem of grammatical inference, to which we apply an active
coevolutionary learning approach. However, this approach would usually require
many feedback queries to be sent to the user. In this work, we extend and generalize
our active learning approach to receive knowledge from multiple oracles, also
known as proactive learning. The ‘user oracle’ represents input received from
the user and the ‘knowledge oracle’ represents available, formalized domain knowledge.
We call our two-oracle approach the ‘first apply knowledge then query’ (FAKT/Q)
algorithm. We compare FAKT/Q to the active learning approach and provide an extensive
benchmark evaluation. As result we find that the number of required user queries
is reduced and the inference process is sped up significantly. Finally, with so-called
On-The-Fly Markets, we present a motivation and an application of our approach
where such knowledge is available.

text: The control of complex systems is of critical importance in many branches
of science, engineering, and industry, many of which are governed by nonlinear
partial differential equations. Controlling an unsteady fluid flow is particularly
important, as flow control is a key enabler for technologies in energy (e.g.,
wind, tidal, and combustion), transportation (e.g., planes, trains, and automobiles),
security (e.g., tracking airborne contamination), and health (e.g., artificial
hearts and artificial respiration). However, the high-dimensional, nonlinear,
and multi-scale dynamics make real-time feedback control infeasible. Fortunately,
these high- dimensional systems exhibit dominant, low-dimensional patterns of
activity that can be exploited for effective control in the sense that knowledge
of the entire state of a system is not required. Advances in machine learning
have the potential to revolutionize flow control given its ability to extract
principled, low-rank feature spaces characterizing such complex systems.We present
a novel deep learning modelpredictive control framework that exploits low-rank
features of the flow in order to achieve considerable improvements to control
performance. Instead of predicting the entire fluid state, we use a recurrent
neural network (RNN) to accurately predict the control relevant quantities of
the system, which are then embedded into an MPC framework to construct a feedback
loop. In order to lower the data requirements and to improve the prediction accuracy
and thus the control performance, incoming sensor data are used to update the
RNN online. The results are validated using varying fluid flow examples of increasing
complexity.

text: "We consider a resource-aware variant of the classical multi-armed bandit\r\nproblem:
In each round, the learner selects an arm and determines a resource\r\nlimit.
It then observes a corresponding (random) reward, provided the (random)\r\namount
of consumed resources remains below the limit. Otherwise, the\r\nobservation is
censored, i.e., no reward is obtained. For this problem setting,\r\nwe introduce
a measure of regret, which incorporates the actual amount of\r\nallocated resources
of each learning round as well as the optimality of\r\nrealizable rewards. Thus,
to minimize regret, the learner needs to set a\r\nresource limit and choose an
arm in such a way that the chance to realize a\r\nhigh reward within the predefined
resource limit is high, while the resource\r\nlimit itself should be kept as low
as possible. We derive the theoretical lower\r\nbound on the cumulative regret
and propose a learning algorithm having a regret\r\nupper bound that matches the
lower bound. In a simulation study, we show that\r\nour learning algorithm outperforms
straightforward extensions of standard\r\nmulti-armed bandit algorithms."

text: The defect-electronic properties of {112} microfaceted surfaces of epitaxially
grown CuInSe2 thin films are investigated by scanning tunneling spectroscopy and
photoelectron spectroscopy techniques after various surface treatments. The intrinsic
CuInSe2 surface is found to be largely passivated in terms of electronic defect
levels in the band-gap region. However, surface oxidation leads to an overall
high density of defect levels in conjunction with a considerable net surface dipole,
which persists even after oxide removal. Yet, a subsequent annealing under vacuum
restores the initial condition. Such oxidation/reduction cycles are reversible
for many times providing robust control of the surface and interface properties
in these materials. Based on ab initio simulations, a mechanism where oxygen dissociatively
adsorbs and subsequently diffuses to a subsurface site is proposed as the initial
step of the observed dipole formation. Our results emphasize the relevance of
oxidation-induced dipole effects at the thin film surface and provide a comprehensive
understanding toward passivation strategies of these surfaces.
