Disease modelling using evolved discriminate function
Precocious diagnosis increases the survival time and patient quality of life. It is a binary classification, exhaustively studied in the literature. This paper innovates proposing the application of genetic programming to obtain a discriminate function. This function contains the disease dynamics used to classify the patients with as little false negative diagnosis as possible. If its value is greater than zero then it means that the patient is ill, otherwise healthy. A graphical representation is proposed to show the influence of each dataset attribute in the discriminate function. The experiment deals with Breast Cancer and Thrombosis & Collagen diseases diagnosis. The main conclusion is that the discriminate function is able to classify the patient using numerical clinical data, and the graphical representation displays patterns that allow understanding of the model

Approximate Vanishing Ideal via Data Knotting
The vanishing ideal is a set of polynomials that takes zero value on the
given data points. Originally proposed in computer algebra, the vanishing ideal
has been recently exploited for extracting the nonlinear structures of data in
many applications. To avoid overfitting to noisy data, the polynomials are
often designed to approximately rather than exactly equal zero on the
designated data. Although such approximations empirically demonstrate high
performance, the sound algebraic structure of the vanishing ideal is lost. The
present paper proposes a vanishing ideal that is tolerant to noisy data and
also pursued to have a better algebraic structure. As a new problem, we
simultaneously find a set of polynomials and data points for which the
polynomials approximately vanish on the input data points, and almost exactly
vanish on the discovered data points. In experimental classification tests, our
method discovered much fewer and lower-degree polynomials than an existing
state-of-the-art method. Consequently, our method accelerated the runtime of
the classification tasks without degrading the classification accuracy.Comment: 11 pages; AAAI'1
Using Recurrent Neural Networks to Optimize Dynamical Decoupling for Quantum Memory
We utilize machine learning models which are based on recurrent neural
networks to optimize dynamical decoupling (DD) sequences. DD is a relatively
simple technique for suppressing the errors in quantum memory for certain noise
models. In numerical simulations, we show that with minimum use of prior
knowledge and starting from random sequences, the models are able to improve
over time and eventually output DD-sequences with performance better than that
of the well known DD-families. Furthermore, our algorithm is easy to implement
in experiments to find solutions tailored to the specific hardware, as it
treats the figure of merit as a black box.Comment: 18 pages, comments are welcom
Errors in quantum optimal control and strategy for the search of easily implementable control pulses
We introduce a new approach to assess the error of control problems we aim to
optimize. The method offers a strategy to define new control pulses that are
not necessarily optimal but still able to yield an error not larger than some
fixed a priori threshold, and therefore provide control pulses that might be
more amenable for an experimental implementation. The formalism is applied to
an exactly solvable model and to the Landau-Zener model, whose optimal control
problem is solvable only numerically. The presented method is of importance for
applications where a high degree of controllability of the dynamics of quantum
systems is required.Comment: 13 pages, 3 figure
Surface Reconstruction from 3D Point Data with a Genetic Programming/Evolution Strategy hybrid
Surface reconstruction is a hard key problem in the industrial domain of computer-aided design (CAD) applications. A physical object, like a workpiece, must be represented in some standard CAD object description format such that its representation can be efficiently used in a CAD process like redesign. To that end, a digitizing process represents the object surface as a weakly-structured discrete and digitized set of 3D points. Surface reconstruction attempts to transform this representation into an efficient CAD representation. Certain classic approaches produce inefficient reconstructions of surface areas that do not correspond to construction logic. Here, a new reconstruction principle in form of a computational-intelligence-based software system is presented that yields logical and efficient representations
Robust monomer-distribution biosignatures in evolving digital biota
Because organisms synthesize component molecules at rates that reflect those
molecules' adaptive utility, we expect a population of biota to leave a
distinctive chemical signature on their environment that is anomalous given the
local (abiotic) chemistry. We observe the same effect in the distribution of
computer instructions used by an evolving population of digital organisms, and
characterize the robustness of the evolved signature with respect to a number
of different changes in the system's physics. The observed instruction
abundance anomaly has features that are consistent over a large number of
evolutionary trials and alterations in system parameters, which makes it a
candidate for a non-Earth-centric life-diagnosticComment: 22 pages, 4 figures, 1 table. Supplementary Material available from
