This is an†¦show more content†¦Numerous plant products have been reported either as insecticides for killing larvae or adult mosquitoes or as repellents for mosquito biting and are one of the best alternatives for mosquito control [2,3].Neem trees, (Azadirachta indica) native of India, belonging to family Meliaceae are fast growing evergreen trees ranging in height from 12 – 24 m. They are widespread in tropical and subtropical regions of the world, including semi-arid and wet- tropical regions [4]. Neem seeds contain approximately 99 biologically active compounds of which azadirachtin, nimbin, nimbidin and nimbolides are major molecules. Many of these derived products have antifeedancy, ovicidal activity, fecundity suppression besides insect growth regulation and repellency against insects [5-10]. Neem products have low toxicity to birds, fish and mammals and are less likely to induce resistance due to their multiple mode of action on insects. In addition to this, i nsect growth regulatory activity of neem weakens the cuticle defence system of the larvae causing easy penetration of pathogenic organisms into insect system. Azadirachtin, a biologically active compound has been promoted as a new insecticide that is considered more eco- friendly than synthetic insecticides. The pesticidal efficacy, environmental safetyShow MoreRelatedReview of Related Literature1643 Words   |  7 PagesReview of Related Literature The review of related literatures of this study is made here in the Philippines and in abroad.

Analysis Of CNN Architecture - 770 Words

Similarly, Perlin [12] systematically used a CNN to extract high-level information from images and videos in the form of soft biometrics. Focusing on faces and people gender recognition, this approach combines convolution techniques, evolutionary computing, and clustering methods. Basically, he proposed the optimization of a predefined CNN architecture by adjusting its weights in an unsupervised way. Initially, the CNN architecture is trained by the classical gradient-based algorithm. Extracted features are grouped by a clustering process and each group is evolved by the Differential Evolution (DE) algorithm. The weights of the CNN are then updated in an unsupervised way to represent the evolved feature vectors. The proposal of clustering†¦show more content†¦These stages represent the network from input to pooling, pooling to pooling, and pooling to output layers. Using this proposal, CNNs evolved by the GA resulted in very different architectures when compared with hand-de signed ones, but often with a better performance. However, a major disadvantage of the proposed framework is the training process, which has to be done from scratch for every evolved new architecture. Fixed-size convolutional blocks also limit the proposed method by not incorporating multi-scaling analysis, and this issue will be present in most of the direct encoded methods designed for this task. Another direct encoding scheme to design CNN architectures is proposed by Masanori et al. [14]. They created new network architectures based on genetic programming. More specifically, a Cartesian Genetic Programming (CGP) encoding scheme that represents the network structure and its connectivity. The main advantage of the proposed method is the flexibility, exploring variable-length architectures and skipping connections resulted in non-standard CNN architectures. To evaluate each architecture evolved by the CGP, they used the validation dataset performance as fitness to the evolutionary programming method. They also used predefined structural blocks called highly functional modules. Using these modules, they simulate the behavior ofShow MoreRelatedHyperspectral Image Classification1485 Words   |  6 PagesClassification is a principle technique in hyperspectral images (HSI) analysis, where a label is assigned to each pixel based on its characteristics.

Reflection on Statistics Learning Goals

Table of Contents Introduction Descriptive Statistics Correlation Hypothesis Testing Future Plans Conclusion References Introduction Statistical knowledge is important to both statisticians and non-statisticians (Broers, 2006). It is, therefore, recommended that people from all disciplines are given basic skills in statistics.Advertising We will write a custom essay sample on Reflection on Statistics Learning Goals specifically for you for only $16.05 $11/page Learn More For this reason, I pursued this course to obtain quantitative skills to be applied and improved on in several ways. In this regard, I hoped to obtain knowledge in designing of experiments, collection and analysis of data, interpretation of results as well as drawing of conclusions (Broers, 2006). Descriptive Statistics Today I can proudly say that my learning objectives were well met. I now have a clear understanding of statistical applications. I know how to collect, organize and de scribe data. I can apply measures of central tendency such as mean, mode and median in data description. I can also use measures of dispersion such as standard deviation and variance to describe data. In addition, I have clear knowledge of normal distributions as well as the conditions to be met for a distribution to be considered normal (Broers, 2006). Correlation Through this course, am able to determine a relationship between two sets of data. I can identify dependent and independent variables and the kind of relationship that exist between them. I can tell if one variable has a causal effect on the other. Furthermore, am able to identify positive, negative and minimal correlations (Broers, 2006). Hypothesis Testing In most cases, it is difficult to collect data on a whole population (Chance, 2002). In this regard, I have obtained necessary skills in sampling techniques. I have skills to analyze data from a sample and make conclusions regarding the entire population by using stat istical probabilities and test of hypothesis. In hypothesis testing, one tries to establish whether the outcomes of a certain study are due to chance or identifiable cause (Chance, 2002). Knowledge in application of significance level, critical value, degrees of freedom and p-value is used. One has to be able to formulate the null and the alternative hypotheses (Chance, 2002).Advertising Looking for essay on math statistics? Let's see if we can help you! Get your first paper with 15% OFF Learn More I am now in a position to use t-test to determine if there are statistically significant differences between two sets of data. In this regard, I understand the required assumptions for t-test to be applied. I have a clear understanding of analysis of variance (ANOVA), both one-way and two-way. I, however, feel that more practice in all these applications will help me perfect my understanding (Chance, 2002). Future Plans This course has given me a clear understanding of the role of statistics in life. Statistics is the most used research tool in medicine, education, psychology, business and economics, among other fields (Rumsey, 2002). It helps in shaping people’s choices in their daily lives. For example, statistical findings can give a clear understanding of implications of some behaviors such as smoking and lead to corrective measures. I have always wanted to build a strong career in research. After taking this course, I have now made up my minds to major in statistics. I wish to have advanced skills in statistics which will enable me handle and analyze large and complex research problems. In this case, the knowledge I have already obtained will give me a head start. Conclusion The objectives I hoped to attain by pursuing this cause have been well achieved. Am now able to design experiments as well as collect, analyze and interpret data. I can apply this knowledge in real life situations and draw conclusions that will help find solutions to s ome problems. However, this course has given me energy to pursue further knowledge in statistics. For this reason, I intend to major in statistics to be in a better position to handle more complex research problems. References Broers, N. J. (2006).
