Expectation-maximization algorithm

machine languages. And therefore, when I had the chance to select my major before the university, I chose Computer Science without any doubt or hesitation. During my undergraduate study at Iowa University, what I learn most are basic languages and algorithms, but some of the advanced courses and self-learning make me feel that computer science demonstrate the essence of natural science - evolution. For example, the development of website from static to dynamic, the progress of the sense…

International Olympiad of Informatics to represent India, there was no doubt that I wanted to build things faster and more efficient than before. However, until then I did not know the booming field called machine learning. I always tried to make algorithms to predict something based on heuristic decisions or even just hardcoded bunch of decisions. It was only in UCSD when I took my first Machine learning course, I realized the true potential of Machines and Data and the sweet bond between…

presently there is no polynomial solution available. In this paper we try to solve this very hard problem using various heuristics such as Simulated Annealing, Genetic Algorithm to find a near optimal solution as fast as possible. We try to escape the local optimum, using these advanced heuristic techniques. Keywords - Genetic Algorithm; Simulated Annealing; heuristic; 1. Introduction Travelling salesman problem can be formulated as “For given list of nodes determine the shortest tour…

as follows. First, M isolated modules, each with the WS structure, are constructed, In order to generate such networks, we used the random rewiring algorithm proposed by Watts–Strogatz[5], Considering a ring graph with n nodes each connected to its m-nearest neighbours by undirected links. The total number of the links are Q=2mn. The rewiring algorithm includes Q steps, and at each step i, link i are chosen and rewired to a node randomly chosen over the graph with the intra-modular rewiring…

known as the first computer programmer. Ada worked with Charles Babbage on his Analytical Engine, a proposed mechanical, general-purpose computer and the beginnings of computer programming. Her notes included the first of what is now known as an algorithm. She is the only legitimate child of the Romantic poet, Lord Byron. ==Young Life and Education== Ada Lovelace was born Augusta Ada Byron King on December 10, 1815, the only legitimate child produced by the famous poet George Lord Byron and…

I was contacted by my old coding teacher and received the opportunity to assist her in leading this year’s coding program. Although I knew I wasn't the best at coding, I saw this offer as a chance for me to learn more about it while sharing the little that I knew with others. During last year's program I got the opportunity to create my own games/programs/apps, and I learned more about JavaScript and its role in businesses. With this information I realized that knowing at least basic code is…

as a “large business or organization that under the law has the rights and duties of an individual and follows a specific purpose”. That specific purpose being the relentless pursuit of profit. All companies are motivated by the idea of profit maximization; corporations are no different. They strive to earn more and more profit. They are not guided by charitable ideals, a moral compass, or the need to help the community. Governed and owned by shareholders, corporations are instructed to seek out…

Describe how the quicksort works including a discussion of the pivot, how it is selected, and why the pivot is important to the quicksort. Let’s start describing what pivot is, its function and why is so important. The pivot is the element that basically divides the array in two halves, where the left half contains the smaller values and the right half contains the greater values. The pivot can be selected in many ways. First, last, middle element, actually any element of the array can be…

The phrase “low expectations” usually has a negative connotation. This makes sense, because people have associated low expectations with unhappiness and failure. This is not always the case, however; sometimes having low expectations can be viewed as pleasant and helpful, whereas having high expectations can cause disappointment. Even William Shakespeare once said that expectations are the root of heartache. Lowering expectations can positively impact happiness by changing one’s outlook on life,…

content areas that are available to the students when students have completed all of their assignments. These fun activity pages are also available for extra practice at home. I will post my classroom expectations on a poster inside of the door to the right at student height. I will talk about my expectation starting the first day of school. I contribute this idea to Harry Wong. Starting everything from the first day of school. Also I would say Dr. Starmack has said, “If You Want It Teach It”…
