A Sample-Aware Database Tuning System With Deep Reinforcement Learning
Based on the relationship between client load and overall system performance, the authors propose a sample-aware deep deterministic policy gradient model. Specifically, they improve sample quality by filtering out sample noise...

Efficient Hyperparameter Tuning with Dynamic Accuracy Derivative-Free Optimization
Many machine learning solutions are framed as optimization problems which rely on good hyperparameters. Algorithms for tuning these hyperparameters usually assume access to exact solutions to the underlying learning problem...
Inferring neural circuit structure from datasets of heterogeneous tuning curves.
Tuning curves characterizing the response selectivities of biological neurons can exhibit large degrees of irregularity and diversity across neurons. Theoretical network models that feature heterogeneous cell populations or...

How do we recall vivid details from our past based only on sparse cues? Research suggests that the phenomenological reinstatement of past experiences is accompanied by neural reinstatement of the original percept. This process...
A Comparative Analysis of Deep Learning Approaches for Network Intrusion Detection Systems (N-IDSs)
Recently, due to the advance and impressive results of deep learning techniques in the fields of image recognition, natural language processing and speech recognition for various long-standing artificial intelligence (AI) tasks...

Energetic Tuning in Spirocyclic Conjugated Polymers.
Precise control of the energy levels in a conjugated polymer is the key to allowing their exploitation in optoelectronic devices. The introduction of spirocycles into conjugated polymers has traditionally been used to enhance...
Reversible optical tuning of GeSbTe phase-change metasurface spectral filters for mid-wave infrared imaging.
Tunable narrowband spectral filtering across arbitrary optical wavebands is highly desirable in a plethora of applications, from chemical sensing and hyperspectral imaging to infrared astronomy. Yet, the ability to reconfigure...

Analysis and Implementation of an Ultra-Wide Tuning Range CMOS Ring-VCO With Inductor Peaking
A novel ring voltage controlled oscillator (VCO) topology is proposed which uses monolithic inductors as a peaking load. Four design examples have been fabricated and tested to verify the proposed circuit structure. The highest...
Band Engineering of Carbon Nitride Monolayers by N-Type, P-Type, and Isoelectronic Doping for Photocatalytic Applications
Since hydrogen fuel involves the highest energy density among all fuels, production of this gas through the solar water splitting approach has been suggested as a green remedy for greenhouse environmental issues due to...

The neural basis of hot and cold cognition in depressed patients, unaffected relatives, and low-risk healthy controls
BACKGROUND: Modern cognitive neuropsychological models of depression posit that negatively biased emotional ("hot") processing confers risk for depression, while preserved executive function ("cold") cognition promotes...
Kernel Parameter Tuning to Tweak the Performance of Classifiers for Identification of Heart Diseases
Medical data analysis is being recognized as a field of enormous research possibilities due to the fact there is a huge amount of data available and prediction in initial stage may save patient lives with timely intervention....

Strategies for active tuning of Wave Energy Converter hydraulic power take-off mechanisms
This paper presents a study of practically implementable active tuning methods
for a Wave Energy Converter (WEC) power take-off (PTO). It is distinguished from other simulation studies by the level of detail and realism in...

Non-Lorentzian SU(1, n) Spacetime Symmetry In Various Dimensions
We discuss non-Lorentzian Lagrangian field theories in $2n-1$ dimensions that
admit an $SU(1,n)$ spacetime symmetry which includes a scaling transformation.
These can be obtained by a conformal compactification of a...
Fine-tuning of ferrocene redox potentials towards multiplex DNA detection
Electron-withdrawing or -donating groups are known to directly affect the Fe(iii/ii) formal potential of ferrocene derivatives by affecting their energy levels relative to the vacuum level. However, perhaps surprisingly, also...
Exact properties of an integrated correlator in N = 4 SU( N ) SYM
Abstract: We present a novel expression for an integrated correlation function of four superconformal primaries in SU(N) N = 4 supersymmetric Yang-Mills (N = 4 SYM) theory. This integrated correlator, which is based on...

Factorisation of 3d N = 4 twisted indices and the geometry of vortex moduli space
We study the twisted indices of $\mathcal{N}=4$ supersymmetric gauge theories
in three dimensions on spatial $S^{2}$ with an angular momentum refinement. We
