For fans of Ada Twist: Scientist comes a fascinating picture book biography of a pioneering female scientist--who loved reptiles Back in the days of long skirts and afternoon teas, young Joan Procter entertained the most unusual party guests: slithery and scaly ones, who turned over teacups and crawled past the crumpets.... While other girls played with dolls, Joan preferred the company of reptiles. She carried her favorite lizard with her everywhere--she even brought a crocodile to school When Joan grew older, she became the Curator of Reptiles at the British Museum. She went on to design the Reptile House at the London Zoo, including a home for the rumored-to-be-vicious komodo dragons. There, just like when she was a little girl, Joan hosted children's tea parties--with her komodo dragon as the guest of honor.With a lively text and vibrant illustrations, scientist and writer Patricia Valdez and illustrator Felicita Sala bring to life Joan Procter's inspiring story of passion and determination.

Discover new realms of outer space in this picture book biography of scientist Gabriela Gonzalez, who immigrated to America and became a ground-breaking scientist. Written by a molecular biologist and illustrated by an award-winning artist, this stunning picture book explores science, space, and history. In 1916, Albert Einstein had a theory. He thought that somewhere out in the universe, there were collisions in space. These collisions could cause little sound waves in the fabric of space-time that might carry many secrets of the distant universe. But it was only a theory. He could not prove it in his lifetime. Many years later, an immigrant scientist named Gabriela Gonzalez asked the same questions. Armed with modern technology, she joined a team of physicists who set out to prove Einstein's theory. At first, there was nothing. But then... they heard a sound. Gabriela and her team examined, and measured, and re-measured until they were sure. Completing the work that Albert Einstein had begun 100 years earlier, Gonzalez broke ground for new space-time research. In a fascinating picture book that covers 100 years, 2 pioneering scientists, and 1 trailblazing discovery, Patricia Valdez sheds light on a little known but extraordinary story.

Hybrid Competitive Learning Method Using the Fireworks Algorithm and Artificial Neural Networks

Hybrid Competitive Learning Method Using the Fireworks Algorithm and Artificial Neural Networks

Fevrier Valdez; Juan Barraza; Patricia Melin

Springer International Publishing AG
2023
nidottu
This book focuses on the fields of neural networks, swarm optimization algorithms, clustering and fuzzy logic. This book describes a hybrid method with three different techniques of intelligence computation: neural networks, optimization algorithms and fuzzy logic. Within the neural network techniques, competitive neural networks (CNNs) are used, for the optimization algorithms technique, we used the fireworks algorithm (FWA), and in the area of fuzzy logic, the Type-1 Fuzzy Inference Systems (T1FIS) and the Interval Type-2 Fuzzy Inference Systems (IT2FIS) were used, with their variants of Mamdani and Sugeno type, respectively. FWA was adapted for data clustering with the goal to help of competitive neural network to find the optimal number of neurons. It is important to mention that two variants were applied to the FWA: dynamically adjust of parameters with Type-1 Fuzzy Logic (FFWA) as the first one and Interval Type-2 (F2FWA) as the second one. Subsequently, based on the outputs of the CNN and with the goal of classification data, we designed Type-1 and Interval Type-2 Fuzzy Inference Systems of Mamdani and Sugeno type. This book is intended to be a reference for scientists and engineers interested in applying a different metaheuristic or an artificial neural network in order to solve optimization and applied fuzzy logic techniques for solving problems in clustering and classification data. This book is also used as a reference for graduate courses like the following: soft computing, swarm optimization algorithms, clustering data, fuzzy classify and similar ones. We consider that this book can also be used to get novel ideas for new lines of research, new techniques of optimization or to continue the lines of the research proposed by the authors of the book.

New Backpropagation Algorithm with Type-2 Fuzzy Weights for Neural Networks

New Backpropagation Algorithm with Type-2 Fuzzy Weights for Neural Networks

Fernando Gaxiola; Patricia Melin; Fevrier Valdez

Springer International Publishing AG
2016
nidottu
In this book a neural network learning method with type-2 fuzzy weight adjustment is proposed. The mathematical analysis of the proposed learning method architecture and the adaptation of type-2 fuzzy weights are presented. The proposed method is based on research of recent methods that handle weight adaptation and especially fuzzy weights.The internal operation of the neuron is changed to work with two internal calculations for the activation function to obtain two results as outputs of the proposed method. Simulation results and a comparative study among monolithic neural networks, neural network with type-1 fuzzy weights and neural network with type-2 fuzzy weights are presented to illustrate the advantages of the proposed method.The proposed approach is based on recent methods that handle adaptation of weights using fuzzy logic of type-1 and type-2. The proposed approach is applied to a cases of prediction for the Mackey-Glass (for ô=17) and Dow-Jones time series, and recognition of person with iris biometric measure. In some experiments, noise was applied in different levels to the test data of the Mackey-Glass time series for showing that the type-2 fuzzy backpropagation approach obtains better behavior and tolerance to noise than the other methods.The optimization algorithms that were used are the genetic algorithm and the particle swarm optimization algorithm and the purpose of applying these methods was to find the optimal type-2 fuzzy inference systems for the neural network with type-2 fuzzy weights that permit to obtain the lowest prediction error.

Dynamic Parameter Adaptation for Meta-Heuristic Optimization Algorithms Through Type-2 Fuzzy Logic

Dynamic Parameter Adaptation for Meta-Heuristic Optimization Algorithms Through Type-2 Fuzzy Logic

Frumen Olivas; Fevrier Valdez; Oscar Castillo; Patricia Melin

Springer International Publishing AG
2018
nidottu
In this book, a methodology for parameter adaptation in meta-heuristic op-timization methods is proposed. This methodology is based on using met-rics about the population of the meta-heuristic methods, to decide through a fuzzy inference system the best parameter values that were carefully se-lected to be adjusted. With this modification of parameters we want to find a better model of the behavior of the optimization method, because with the modification of parameters, these will affect directly the way in which the global or local search are performed.Three different optimization methods were used to verify the improve-ment of the proposed methodology. In this case the optimization methods are: PSO (Particle Swarm Optimization), ACO (Ant Colony Optimization) and GSA (Gravitational Search Algorithm), where some parameters are se-lected to be dynamically adjusted, and these parameters have the most im-pact in the behavior of each optimization method.Simulation results show that the proposed methodology helps to each optimization method in obtaining better results than the results obtained by the original method without parameter adjustment.

Connection-Ship

Connection-Ship

Sergio Patricio Valenzuela Valdés

SCHOLARS' PRESS
2023
pokkari
The research project has a starting point: the observation of isolated quantum physicists still working together in teams during their experiments and the question of what is special about the experience the cooperating scientists are making under these conditions. Does something similar exist in art? How do connections arise between the practitioners? And: How does an artistic practice work that influences and attracts other artists and can bring new content into the social sphere? Here the 'body' is used as concept, medium and tool, because it can probe perception and consciousness in such work- and learning processes. Via the body - working in isolation - a bridge can be built between the different isolated ways of working. This bridge is summarized by the term "connection-ship". Methodologically, the study is located in the literature debate and applied research. It shows that the initial conditions of research and the creative process can be distracted from the planned creative process by many aspects and conditions. However, the experience of 'connection' as an incorporated process of being together always remains.
