Estimation of Distribution Algorithms TutorialMartin Pelikan
Probabilistic model-building algorithms (PMBGAs), also called estimation of distribution algorithms (EDAs) and iterated density estimation algorithms (IDEAs), replace traditional variation of genetic and evolutionary algorithms by (1) building a probabilistic model of promising solutions and (2) sampling the built model to generate new candidate solutions. PMBGAs are also known as estimation of distribution algorithms (EDAs) and iterated density-estimation algorithms (IDEAs).
Replacing traditional crossover and mutation operators by building and sampling a probabilistic model of promising solutions enables the use of machine learning techniques for automatic discovery of problem regularities and exploitation of these regularities for effective exploration of the search space. Using machine learning in optimization enables the design of optimization techniques that can automatically adapt to the given problem. There are many successful applications of PMBGAs, for example, Ising spin glasses in 2D and 3D, graph partitioning, MAXSAT, feature subset selection, forest management, groundwater remediation design, telecommunication network design, antenna design, and scheduling.
This tutorial provides a gentle introduction to PMBGAs with an overview of major research directions in this area. Strengths and weaknesses of different PMBGAs will be discussed and suggestions will be provided to help practitioners to choose the best PMBGA for their problem.

Power Electronics in Electric and Hybrid Vehicles 2014 Report by Yole Develo...Yole Developpement
A $16B market by 2023, a change of business model, and significant technical changes: how will electric and hybrid vehicles change the power electronics industry?
EV/HEV MARKET: A BURGEONING MARKET FULL OF PROMISES AND UNCERTAINTIES
Electric and hybrid vehicles have been presented as a huge market over the last few years, but in 2013 only 100K 100% electric vehicles were sold, and only 2M EV/HEV cars in total. For 2014, technological and architectural upgrades have been made and are ready to deploy, but the most important need is still to convince the end-user to change their habits and transition to an EV/HEV.
Charging infrastructure development, battery cost reduction and power density increase are pushing the EV/HEV market forward. Moreover, as the market grows and the technology develops, the price difference between EV/HEV vehicles and gas-powered vehicles will progressively shrink, thus further accelerating EV/HEV market advancement. Also, governmental restrictions on CO2 output are becoming increasingly aggressive worldwide (58mpg for the United States in 2025, and in 2020 for Europe). For all of these reasons, we expect end-users to be swayed by electric energy’s low cost and governmental incentives, making the EV/HEV market very attractive. In this report you will find a detailed analysis of markets by type, as well as an analysis of the positive and negative trends impacting the EV/HEV market.

Automatic Skin Lesion Segmentation and Melanoma Detection: Transfer Learning ...Zabir Al Nazi Nabil
Industrial pollution resulting in ozone layer depletion has influenced
increased UV radiation in recent years which is a major environmental risk factor for invasive skin cancer Melanoma and other keratinocyte cancers. The incidence of deaths from Melanoma has risen worldwide in past two decades.
Deep learning has been employed successfully for dermatologic diagnosis. In
this work, we present a deep learning based scheme to automatically segment
skin lesions and detect melanoma from dermoscopy images. U-Net was used
for segmenting out the lesion from surrounding skin. The limitation of utilizing
deep neural networks with limited medical data was solved with data augmentation and transfer learning. In our experiments, U-Net was used with spatial
dropout to solve the problem of overfitting and different augmentation effects
were applied on the training images to increase data samples. The model was
evaluated on two different datasets. It achieved a mean dice score of 0.87 and a
mean jaccard index of 0.80 on ISIC 2018 dataset. The trained model was assessed on PH² dataset where it achieved a mean dice score of 0.93 and a mean
jaccard index of 0.87 with transfer learning. For classification of malignant
melanoma, a DCNN-SVM model was used where we compared state of the art
deep nets as feature extractors to find the applicability of transfer learning in
dermatologic diagnosis domain. Our best model achieved a mean accuracy of
92% on PH² dataset. The findings of this study is expected to be useful in cancer diagnosis research.

Many learning tasks can be summarized as learning a mapping from a structured input to a structured output, such as machine translation, image captioning, image style transfer, and image dehazing. Such mappings are usually learned on paired training data, where an input sample and its corresponding output are both provided. Collecting paired training data often involves expensive human annotation, and the scale of paired training data is therefore often limited. As a result, the generalization ability of models trained on paired data is also limited. One way to mitigate this issue is learning with unpaired data, which is far less expensive to collect. Taking machine translation as an example, the unpaired training data can be collected separately from newspapers in the source language and target language without any annotation. The challenge of unpaired learning turns into how to align the unpaired data. With carefully designed objectives, unpaired learning has achieved remarkable progress on several tasks. This talk will cover the data collection and training methods of several unpaired learning tasks to illustrate the power of learning with unpaired data.
plug in hybrid electrical vehicals seminar ppt by MD NAWAZMD NAWAZ
A 'gasoline-electric hybrid car' or 'Plug in hybrid electric vehicle' is a vehicle which relies not only on batteries but also on an internal combustion engine which drives a generator to provide the electricity and may also drive a wheel. It has great advantages over the previously used gasoline engine that drives the power from gasoline only. It also is a major source of air pollution. The objective is to design and fabricate a two wheeler hybrid electric vehicle powered by both battery and gasoline. The combination of both the power makes the vehicle dynamic in nature. It provides its owner with advantages in fuel economy and environmental impact over conventional automobiles. Hybrid electric vehicles combine an electric motor, battery and power system with an internal combustion engine to achieve better fuel economy and reduce toxic emissions.
In HEV, the battery alone provides power for low-speed driving conditions where internal combustion engines are least efficient. In accelerating, long highways, or hill climbing the electric motor provides additional power to assist the engine. This allows a smaller, more efficient engine to be used. Besides it also utilizes the concept of regenerative braking for optimized utilization of energy. Energy dissipated during braking in HEV is used in charging battery. Thus the vehicle is best suited for the growing urban areas with high traffic. Initially the designing of the vehicle in CAD, simulations of inverter and other models are done. Equipment and their cost analysis are done. It deals with the fabrication of the vehicle. This includes assembly of IC Engine and its components. The next phase consists of implementing the electric power drive and designing the controllers. The final stage would consist of increasing the efficiency of the vehicle in economic ways.

2013 ASPRS Track, Ozone Modeling for the Contiguous United States by Michael ...GIS in the Rockies
Ozone (O3) is a powerful oxidizer (e.g. reacting with oxygen). Ozone in the upper atmosphere is considered beneficial due to the ability of the compound to filter harmful UV rays generated from the sun. However, ground level concentrations of ozone influence animal and plant health. In animals, one symptom of ground level ozone is lung tissue damage resulting in respiratory complications. Excess ozone in plants can cause excessive water loss; thus, emulate drought conditions. Ozone simulates the stomata cell in plant leaves so that these cells do not function properly. That is the stomata cells do not close completely, resulting in excess water loss (Smith et al. 2008). Anthropogenic ozone can be created via internal combustion engines and coal fired power plants.
Collecting data from the Environmental Protection Agency (EPA) CASTnet site for the time periods 1990 to 2010 I use spatial interpolation techniques to create an ozone surface concentration for the contiguous United States.

The sea surface temperature (SST) anomalies are believed to be the most important factor of the forced atmospheric circulation, which causes temperature anomalies (i.e., anomalously warm/cold winter). We present two independent methods for predicting temperature over 2 meters(T2M) from SST. The first method uses a statistical learning algorithm based on maximum correlation analysis; the second method relies on algorithmic differentiation of the climate model: estimation of T2M sensitivity to SST.
Estimation of Weekly Reference Evapotranspiration using Linear Regression and...IDES Editor
The study investigates the applicability of linear
regression and ANN models for estimating weekly reference
evapotranspiration (ET0) at Tirupati, Nellore, Rajahmundry,
Anakapalli and Rajendranagar regions of Andhra Pradesh.
The climatic parameters influencing ET0 were identified
through multiple and partial correlation analysis. The
sunshine, temperature, wind velocity and relative humidity
mostly influenced the study area in the weekly ET0 estimation.
Linear regression models in terms of the climatic parameters
influencing the regions and, optimal neural network
architectures considering these climatic parameters as inputs
were developed. The models’ performance was evaluated with
respect to ET0 estimated by FAO-56 Penman-Monteith method.
The linear regression models showed a satisfactory
performance in the weekly ET0 estimation in the regions
selected for the present study. The ANN (4,4,1) models,
however, consistently showed a slightly improved performance
over linear regression models.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

PIML is of critical importance for data- and physics-driven science and engineering
applications
PIML models can replace computationally intensive numerical simulators
PIML models can be applied to predict complex processes when:
• physics is not well understood
• numerical models cannot be developed (due to physics complexity)
Training PIML models is 1-2 orders of magnitude faster than traditional ML models

“Deep Learning is dead. Long Live Differentiable Programming!”
Yann LeCun, Chief AI Scientist at Facebook, and one of the leading ML experts in the
world
Differentiable Programming for PIML can be done efficiently only in
C/C++, FORTRAN, Python, scikit-learn, TensorFlow, PyTorch cannot do it
