Linear algebra is a useful tool with many applications within the computer science field. This paper will cover the various applications of linear algebra in computer science including: internet search, graphics, speech recognition,and artificial intelligence. A major focus of linear algebra in computer science is internet searches, which involves finding techniques for effectively storing and searching through information.
In the year 2000 there was an estimated 2.5 billion web pages on the internet, with a growth rate of 7.3 million per day. Linear algebra is used in the organization and sorting of these web pages when storing them in an internet search database. The vector space model;is used to enhance search results by representing them as two vectors, the document vector and query vector. Each dimension in the vector corresponds to a different term. If the term occurs in the document, its value in the vector is a non-zero value. Several different ways of computing the term weights have been developed, one of which is the frequency-inverse document frequency (tf-idf) weights. The frequency portion if td-idf refers to the frequency of the term within the document. The inverse document frequency is the log function of the total number of documents / divided by the number of documents in which the term appears.The frequency-inverse document model just multiplies these 2 values. Using the cosine similarity between the document and query vector allows the computer to group data together or output data that is similar. The major advantages of using this model over the standard boolean model is that it allows ranking of documents according to their relevance, and it allows partial matching. There are a large number of variations of ...

...ing in statistical machine learning are probability distributions and parameter spaces which are represented using vectors. Currently the use of linear algebra within AI’s can be avoided when using prepared libraries, but to understand how and why the algorithms work in the AI unit you will need linear algebra.
Linear algebra has a large impact on the computer science field and is one of the most important tools to learn if you are committed to excelling in computer science. Linear algebra has its effect in a large number of applications in computer science but some of the most significant impact are its use for organizing and sorting through large amounts of web pages in the internet search database, its ability to transform graphical images, it’s impact on voice recognition, and lastly its ability to provide AI with the concept of statistical machine learning.

We live in a world that can’t live without binary code anymore. Computers have pervaded so deep in our lives that they are now being called ubiquitous. With phenomenal increase in users, has come a phenomenal increase in data. We generate a vast amount of data through activities on our computing devices making it necessary to employ intelligent algorithms which enable the system to learn from and analyze this vast dataset. Fortunately, the advent of Distributed Computing has created avenues to access virtually limitless computing power even through mobile devices thus, allowing us to use highly complex and large scale algorithms. However, with all this power under the hood, it is important to make the computers as usable and receptive to users as possible. I believe this interdisciplinary paradigm will have far reaching impact on industries, governments as well as our daily lives which is why I am so interested in research concerning Information Management and Analytics, Artificial Intelligence, Human Computer Interaction, and Mobile and Internet Computing.
Bill Gates, Steve Jobs, and Mark Zuckerberg. These three men all have one thing in common, they became very wealthy from investing in the future of computers. A person may decide to go to college and make a career out of working with computers because of the potential earnings and consistent need of individuals who have studied computer sciences. This paper is going to inform you on what an individual does with a Computer Science degree, education needed to work in this field, and why we need people to do this kind of work.
The computing industry as a whole becomes more prosperous, exciting and attractive as an employment prospect each day. It spans a wide range of modern applications, as does my interest in the subject. I see computing science as a gateway into new realms of computing, where the highly challenging and demanding work may reap rewards of an equivalent level.
If the nineteenth century was an era of the Industrial revolution in Europe, I would say that computers and Information Technology have dominated since the twentieth century. The world today is a void without computers, be it healthcare, commerce or any other field, the industry won’t thrive without Information Technology and Computer Science. This ever-growing field of technology has aroused interest in me since my childhood. After my twelfth grade, the inherent ardor I held for Computer Science motivated me to do a bachelors degree in Information Technology. Programming and Math, a paragon of logic and reasoning, have always been my favorite subjects since childhood.
In today’s fast paced technology, search engines have become vastly popular use for people’s daily routines. A search engine is an information retrieval system that allows someone to search the...
Eigenvalues and eigenvectors is one of the important topics in linear algebra. The purpose of this assignment is to study the application of eigenvalues and eigenvectors in our daily life. They are widely applicable in physical sciences and hence play a prominent role in the study of ordinary differential equations. Therefore, this assignment will provide explanations on how eigenvalues and eigenvectors will be functional in a prey-predator system. This will include background, history of the concept and explanation on what is meant by eigenvalues, eigenvectors and prey-predator system. Other than that, models and application of the eigenvalues and eigenvectors in prey-predator system will also be included in this assignment. Necessary appendix such as graphs will be attached with the assignment.
Search engines are not very complex in the way that they work. Each search engine sends out spiders to bots into web space going from link to link identifying all pages that it can. After the spiders get to a web page they generally index all the words on that page that are publicly available pages at the site. They then store this information into their databases and when you run a search it matches they key words you searched with the words on the page that the spider indexed. However when you are searching the web using a search engine, you are not searching the entire web as it is presently. You are looking at what the spiders indexed in the past.

Information Retrieval (IR) is to represent, retrieve from storage and organise the information. The information should be easily access. User will be more interested with easy access information. Information retrieval process is the skills of searching for documents, for information within documents and for metadata about documents, as well as that of searching relational databases and the World Wide Web. According to (Shing Ping Tucker, 2008), E-commerce is rapidly a growing segment in the internet.
Information Retrieval is simply a field concerned with organizing information. In other terms, IR is emphasizing the range of different materials that need to be searched. Others researcher said that IR is the contrast between the strong structure and typing a database system with the lack of structure in the objects typically searched in IR. The actual process in information retrieval systems is it has to deal with incomplete or under specified information in the form of the queries issued by users. IR uses the techniques of storing and recovering and often disseminating recorded data especially through the use of a computerized system.
Did your phone just ring? Or was that your computer notifying you of a new email? Since the Digital Revolution and the addition of digital electronics like the personal computer, software-based technology has always been an essential aspect of our lives. Something that would have taken up an entire classroom can now fit within the grasp of your hands thanks to the efforts of various computer scientists and engineers, making our lives much easier.
The computer evolution has been an amazing one. There have been astonishing achievements in the computer industry, which dates back almost 2000 years. The earliest existence of the computer dates back to the first century, but the electronic computer has only been around for over a half-century. Throughout the last 40 years computers have changed drastically. They have greatly impacted the American lifestyle. A computer can be found in nearly every business and one out of every two households (Hall, 156). Our Society relies critically on computers for almost all of their daily operations and processes. Only once in a lifetime will a new invention like the computer come about.
Today, it is so clear to see many significant changes in the education around the world because of computer. Almost all schools and universities have become involved with computer’s system to provide an appropriate environment for students to study or prepare for classes. For example, Oklahoma State University provides a crucial program called Desire to Learn (D2L) which is an online website made for teachers to post assignments, grades, and other notes related to the courses. And this program is so helpful because it gives students a nice chance to study from home, participate on announced events, or even avoid students from getting in trouble such as receiving email when weather conditions are not good to attend classes. Moreover, in the past students and researchers used to face difficulties to get information and data related to subject. However, nowadays computer makes it easier because of the gigantic data and information that computer has. Computer has a revolutionary influence in enhancing our education.
