Back Propagation For Classification ( Research Essay )

Back Propagation for Classification (Research Essay) Linfeng Gu Introduction This research essay mainly discusses back propagation used in artificial neural networks based on three research papers. From the second section, each section contains the discussion of one research paper. In the first research paper, researchers apply feed forward neutral networks with back propagation in medical fields and present several statistical normalization methods. [4] In the second research paper, researchers focus on a varia ¬tion of the standard back propagation algorithm. Since nodes of each layer are fully connected in the standard back propagation neural networks, huge computing resour ¬ces are cost to adjust weights. Therefore researchers pro ¬pose an exclusive connecting network. In the third research paper, researchers introduce an adap ¬tive gain for the activation function used in back propa ¬gation neural networks in order to get faster convergence and better performance in classification problems. Statistical Normalization and Back Propaga ¬tion for Classification Background Study In medical fields, clinical databases are recently becoming increasingly large so that more experts are needed to deal the data. Since the majority of the medical data sets are non-linear, it is difficult for people to analysis and classify a large amount of them. Therefore if there are some specific algorithms which could automatically handle numerous data, it could efficiently reduce the humanShow MoreRelatedThe Importance Of Echocardiography For Clinical Practice As They Are Used For Screening, Diagnosis, And Diagnosis2604 Words   |  11 Pages Module: Clinical Instrumentation Module Code: 5BM020 Echocardiography Word count: 1973 21/1/2015 Raj Chavda 1112009 Introduction In this essay I will be discussing the importance of echocardiography in clinical practice as they are used for screening, diagnosis, guiding treatment, assessing recovery and monitoring care.

An Inspector Calls Essay Example For Students

An Inspector Calls Essay Both Mr Birling From An Inspector Calls And Ebeneezer Scrooge From Christmas Carol Are Visited By Outsiders. Compare And Contrast The Two Characters And How They Are Influenced By The Outsiders.  An Inspector Calls is a play written by J.B Preistly in year 1908. An Inspector Calls and Christmas Carol have a main theme to them, which is about holism and individualism but we see how two similar characters dealing with these issues. The author is showing how wealthy rich business owners deal with social considerations and responsibility also. Charles Dickens writes the Christmas Carol. The play concentrates on responsibility and social considerations and also four outsiders visit the character in Christmas Carol. Mr Birling is the one of the main characters out of six in An Inspector Calls. Mr Birling is a wealthy business owner who we see fails to deal with responsibility and social considerations. In Christmas Carol Ebeneezer Scrooge is main character, he also owns a business. Scrooge also shows how he succeeds to deal with responsibility and social considerations. An outsider called Inspector Goole visits Mr Birling. Scrooge is visited by four outsiders they are; his late business partner and best friend Jacob Marley and the ghosts of past, present and future. Outsiders means ghost or sprit all, the outsiders that visit Mr Birling and Scrooge are sprits or ghosts. Inspector Gooles name is a pun on ghoul meaning sprit or ghost. The outsiders visit these characters due to lack of responsibility they show as businessmen and how they treat their employees. Also what their social considerations however these characters are individualist they think for them self not for anyone else. The Outsiders visit Mr Birling and Scrooge to preach holism. Conversely Mr Birling and Scrooge are similar, they both own business and their responsibility, which is to care for his employee not be individualist and to be holist which to think for everyone. But Mr Birling and Scrooge do not take care of their employees, as they are individualists. Mr Birling sacked his employee Eva Smith because she wanted only a couple of more shillings nothing more. Mr Birling sad that if he gave Eva Smith the increase in wages. Mr Birling considers his business first then his employees and him self-first as well. Mr Birling is greedy:  Well, its my duty to keep labour costs down, and if Id agreed to this demand fro a new rate wed have added about twelve per cent to out labour costs. This quote shows he is bothered about his labour costs, he does not want high labour cost then he will not make any profits for himself and also he self important he does not care if his employees cannot cope with their wages he does not show responsibility for his workers.  Scrooge does not let his clerk Bob Cratchet have Christmas off he says it is a way off picking a poor persons pocket on Christmas day, but in the end he lets him have Christams off but he can not have following day off:   A poor excuse picking a mans pocket every twenty-fifth of December. However Scrooge is moaning to Bob that he pays him for nothing because he doesnt do any work:   You dont think me ill-used when I pay a days wages for no work.  Both of the characters are tight fisted, they are very selfish because they do not let their workers have a pay increase. Both characters do not let their workers wages go up. Mr Birling sacked five ringleaders because of this. One of those ringleaders was Eva Smith, this was one of the first chain of events, which lead to her death. Mr Birling is not responsible because he does not care for his workers or their lives. All he wants is his knighthood: Shakespeare's Presentation of Isabella in Act 5 of the Play EssayImplying that he only enjoys them without the company of the misses and after meals. As we carry on, we see how Mr Birling stereotypes women and he says that there all the same as when they are out the room Eric says he left them in the drawing-room talking about cloths which he then carries on to say there all made over cloths and doesnt understand it, Mr Birling telling him that he must understand that women cloths are basically all they have to enjoy as there husbands are always working. Birling does not seem to like women very much, specially lower class women, as he describes Eva Smith wretched girls this showing that the men are not really meant to care even though the woman has just died because as long as he had no undertake in it, everything all right. When Gerald has admitted to having had an affair we see how Birling implies its a common thing Now, Sheila, Im not defending him. But you must understand that a lot of men- this tells us that the respect he has for women is not very high because if he can say that affairs are common within a man marriage, how must it be for the women. That quote also implies that he may have also had an affair in the past. Towards the end we see that instead of the men and women going against each other its the other way round, except its the older generation against the young, which is Mr Birling Mrs Birling, and Sheila and Eric teaming up.  The play finishes with the whole thing about the inspector being a hoax and then it really happens in reality, as if the past was being replayed. Throughout the play we mostly see the men doing the bad thing and the women covering up for them.

My Grandmothers Landuryroom Essays - Bathing, Bathrooms, Hygiene

My Grandmothers Landuryroom My Grandmothers Landuaryroom The first time I walked through my grandparent's house I thought the living room with all of its beauty was my favorite room, but I changed my mind. As I continued through the house, I approached the master bathroom, which was just lovely. Later I discovered that their bathroom was my favorite place in her house. The colors in the bathroom were peaceful. The reflection from the day lily wallpaper, towels, and rugs added a brilliant blue color to the room. When I was standing at the door, the next thing I saw was the curtain that hung above the whirl pool bathtub that sits in the opposite corner of the bathroom from where I was standing. The curtain was a beautiful light lavender blue. As I looked down, the shiny new white tile floor gleamed up at me. The fixture and bathing areas were just great. The stand-up shower with its graceful, clear glass doors really got my attention. The whirlpool bathtub in its own little corner had real day lilies surrounding it. The toilet with the oak surface seat and brass handle sat in its own little corner of the bathroom. The two-sink counter was beautiful, it had a brass tray with small, old perfume bottles on it: on each side of the sinks there is hanging medicine cabinets. I believe my grandparents's bathroom is the most elegant of all bathroom's that I have ever seen. I choose this part this place also because it is not an place most people go for beauty it a place where people go to do there business. I go there to relax or to just get lost in the elegance of the room. Creative Writing

The Large Hadron Collider and the Frontier of Physics

The Large Hadron Collider and the Frontier of Physics The science of particle physics looks at the very building blocks of matter - the atoms and particles that make up much of the material in the cosmos. Its a complex science that requires painstaking measurements of particles moving at high speeds. This science got a huge boost when the Large Hadron Collider (LHC) began operations in September 2008. Its name sounds very science-fictiony but the word collider actually explains exactly what it does: send two high-energy particle beams at nearly the speed of light around a 27-kilometer long underground ring. At the right time, the beams are forced to collide. Protons in the beams then smash together and, if all goes well, smaller bits and pieces - called subatomic particles - are created for brief moments in time. Their actions and existence are recorded. From that activity, physicists learn more about the very fundamental constituents of matter. LHC and Particle Physics The LHC was built to answer some incredibly important questions in physics, delving into where mass comes from, why the cosmos is made of matter instead of its opposite stuff called antimatter, and what the mysterious stuff known as dark matter could possibly be. It could also provide important new clues about conditions in the very early  universe when gravity and electromagnetic forces were all combined with the weak and strong forces into one all-encompassing force. That only happened for a short time in the early universe, and physicists want to know why and how it changed.   The science of particle physics is essentially the search for  the very basic building blocks of matter. We know about the atoms and molecules that make up everything we see and feel. The atoms themselves are made up of smaller components: the nucleus and electrons. The nucleus is itself made up of protons and neutrons. Thats not the end of the line, however. The neutrons are made up of subatomic particles called quarks. Are there smaller particles? Thats what particle accelerators are designed to find out. The way they do this is to create conditions similar to what it was like just after the Big Bang - the event that began the universe. At that point, some 13.7 billion years ago, the universe was made only of particles. They were scattered freely through the infant cosmos and roamed constantly. These include mesons, pions, baryons, and hadrons (for which the accelerator is named). Particle physicists (the people who study these particles) suspect that matter is made up of at least twelve kinds of fundamental particles. They are divided into quarks (mentioned above) and leptons. There are six of each type. That only accounts for some of the fundamental particles in nature. The rest are created in super-energetic collisions (either in the Big Bang or in accelerators such as the LHC). Inside those collisions, particle physicists get a very fast glimpse at what conditions were like in the Big Bang, when the fundamental particles were first created. What is the LHC? The LHC is the largest particle accelerator in the world, a big sister to Fermilab in Illinois and other smaller accelerators. LHC is located near Geneva, Switzerland, built and operated by the European Organization for Nuclear Research, and used by more than 10,000 scientists from around the world. Along its ring, physicists and technicians have installed extremely strong supercooled magnets that guide and shape the beams of particles through a beam pipe). Once the beams are moving fast enough, specialized magnets guide them to the correct positions where the collisions take place. Specialized detectors record the collisions, the particles, the temperatures and other conditions at the time of the collision, and the particle actions in the billionths of a second during which the smash-ups take place. What Has the LHC Discovered? When particle physicists planned and built the LHC, one thing they hoped to find evidence for is the Higgs Boson. Its a particle named after Peter Higgs, who predicted its existence. In 2012, the LHC consortium announced that experiments had revealed the existence of a boson that matched the expected criteria for the Higgs Boson. In addition to the continued search for the Higgs, scientists using the LHC have created whats called a quark-gluon plasma, which is the densest matter thought to exist outside of a black hole. Other particle experiments are helping physicists understand supersymmetry, which is a spacetime symmetry that involves two related types of particles: bosons and fermions. Each group of particles is thought to have an associated superpartner particle in the other. Understanding such supersymmetry would give scientists further insight into whats called the standard model. Its a theory that explains what the world is, what holds its matter together, and the forces and particles involved. The Future of the LHC Operations at the LHC have included two major observing runs. In between each one, the system is refurbished and upgraded to improve its instrumentation and detectors. The next updates (slated for 2018 and beyond) will include an increase in collisional velocities, and a chance to increase the luminosity of the machine. What that means is that LHC will be able to see ever more rare and fast-occurring processes of particle acceleration and collision. The faster the collisions can occur, the more energy will be released as ever-smaller and harder-to-detect particles are involved. This will give particle physicists an even better look at the very building blocks of matter that make up the stars, galaxies, planets, and life.

Political power of women Research Paper Example | Topics and Well Written Essays - 1750 words

Political power of women - Research Paper Example However, while women in the region continue to rise into the highest positions of leadership in the region, the rise in the number of such leaders does not result in the protection of the rights of women (Pamela and Melanie 65). The position of women in the two societies contrasts thereby depicting definite pattern of weak political institutions that do not consider the position of women in the Asian societies. The position and participation of women in politics should facilitate the inclusion of their rights and roles in the constitution as the essay below portrays. The democratic processes in the countries are illusionary and use the high political positions as rewards to women who lose either fathers or husbands in political assassinations. The Sri-Lankan female president for example rose to power after the assassination of her husband who served as the president prior to his murder. While the women hold the highest positions in office, they work in heavily bureaucratic systems of ten working under the influence of men. This explains the inability of the female presidents to improve the status of women in the countries. The status of women in Asia is appalling with some societies showing abject disregard to the fundamental human rights. The rise of specific women into the positions of power does not help address such deeply entrenched social structures that perpetuate the disregard of the fundamental human rights (Pamela and Melanie 231). India, the world most populous nation and a strong economy in Asia has had few women in leadership positions. This perpetuates the traditional stereotypes in the society most of which support the disregard to the rights of women. The recent case of a girl gang raped in a public bus in Mumbai depicts the hopelessness of women in the country. The incident portrayed the fact that numerous rape cases in the country go unreported. The police in the country lack the motivation to investigate crimes against women. The lack of both motivation and resources to investigate cases of crimes against women and bring the suspects to book as depicted by the actions of the police investigating the case of the young girl gang raped in bus shows the lack of representation of women in the society. The political system in the country does not uphold the values and rights of women thus compelling female rape victims to feel ashamed and shun any attempt to report such atrocities. The police force in the country consists of men who therefore uphold the laws that safeguard the rights of men often disregarding the plight of women. The police force in India for example requires effective reforms in order to increase the number of women in the force. The presence of a female president surrounded by male cabinet secretaries and male parliamentarians does not help elevate the position of women in the society. The change in political representation requires enactment of legislations that safeguard the rights of women. Additionally t his requires an attitudinal overhaul in order to influence the feelings and thoughts of the populace in order to recognize the rights and roles of women (Gelb and Marian 41). The solution to the social problems in Asia is improved female representation. As determined above, having a female president is not enough since an individual may not influence the political and policy changes required to alleviate the plight of women in the s

Franklin D. Roosevelts New Deal Essay Example for Free

Franklin D. Roosevelts New Deal Essay In the first hundred days of FDR’s presidency he passed fifteen major bills. One of the most famous was the proclamation nationally issued that all banks would be temporarily closed, forming the Emergency Banking Act. Other bills passed in this â€Å"Hundred Days of Action† include the Tennessee Valley Authority Act, the Beer- Wine Revenue Act, the creation of the Civilian Conservation Corps, and the Home Owners Loan Act. These and many other like bills were the shining light at the end of tunnel for Americans as Roosevelt came into office striving to end the Depression. Fireside chats, which were radio broadcasts, were a way for Roosevelt to connect with Americans on a more personal level while managing to give them a sense of comfort. He was able to give insight to the general public through these broadcasts. He gave Americans hope that things would be better and they put their trust in him. Successful in short term relief, the New Deal did not end the Great Depression but did push the economic circumstances to a higher quality. As far as long term effects are concerned our country’s governmental structure has been forever changed. After the New Deal’s policies were administered a dominant new political coalition was in place, in turn, creating Democratic majority that lasted for half a century. Roosevelt gave Americans something new and different to expect from government and pushed the country toward its post war boom that many say was the â€Å"golden age of American capitalism†. Through the New Deal and his presidency he formed our views and outlook to how the modern American government should and is conducted. Programs put in place by the New Deal gave hope to Americans in this morbid, bleak time. He gave us the layout in which we practice modern government. As said by Roosevelt, The country needs and, unless I mistake its temper, the country demands bold, persistent experimentation. It is common sense to take a method and try it: If it fails, admit it frankly and try another. But above all, try something. He tried and pushed forward through a troublesome, oppressive time that seemed as if it would not ever end. If he had not done so it is unimaginable to think what would have become of our country.
