Final collaborative research projects will allow you to apply your modeling skills to a cognitive phenomenon that you’re interested in. Through in class activities and readings of both classic and contemporary research papers on computational cognitive modeling, we’ll build up an understanding of how different modeling choices lead to different predictions about human behavior and investigate potential practical uses of cognitive models. Prerequisites: Computer Science 111 or instructor permissionĦ credits Formal or Statistical Reasoning, Quantitative Reasoning Encounter offeredĪnya Vostinar, Layla Oesper, Aaron Bauer, Eric Alexander, Anna RaffertyĬS 328: Computational Models of Cognition How are machine learning and human learning similar? What sorts of things can people learn, and how can we apply computer science ideas to characterize cognition? This interdisciplinary course will take a computational modeling approach, exploring how models can help us to better understand cognition and observing similarities between machine learning methods and cognitive tasks.
Students who have received credit for a course for which Computer Science 201 is a prerequisite are not eligible to enroll in Computer Science 201. How can Google take your query, compare it to billions of web pages, and return the answer in less than one second? How can one store information so as to balance the competing needs for fast data retrieval and fast data modification? To help us answer questions like these, we will analyze and implement stacks, queues, trees, linked lists, graphs, and hash tables.

Did you ever get the feeling that “there has to be a better/smarter way to do this problem”? The Data Structures course is all about how to store information intelligently and access it efficiently. should behave.Think back to your favorite assignment from Introduction to Computer Science. The control unit also dictates how the memory, input output devices, arithmetic logic unit etc. It transfers data throughout the computer as required including from storage unit to central processing unit and vice versa. This unit controls all the other units of the computer system and so is known as its central nervous system. The arithmetic logic unit and the control unit together form the central processing unit. The control unit transfers data from storage unit to arithmetic logic unit when calculations need to be performed. It can perform operations like addition, subtraction, multiplication, division etc. Secondary storage contains a large amount of data permanently.Īll the calculations related to the computer system are performed by the arithmetic logic unit. The data from secondary storage needs to be brought into the primary storage before the CPU can use it. Secondary or external storage is not directly accessible by the CPU.
It is traditionally divided into primary storage and secondary storage.Primary storage is also known as the main memory and is the memory directly accessible by the CPU. Storage unit contains many computer components that are used to store data. The different output devices are monitors, printers, speakers, headphones etc. Most of the output data is the form of audio or video. The output unit provides the results of computer process to the users i.e it links the computer with the external environment. are the most commonly used input devices. It takes data from the input devices, converts it into machine language and then loads it into the computer system. So, basically it links the external environment with the computer. The input unit provides data to the computer system from the outside. The control unit controls all the other units as well as their data.ĭetails about all the computer units are − This is because stored data is computed on before being stored again. The data constantly moves from storage unit to ALU and back again. Similarly, the computed data travels from ALU to output unit. The input data travels from input unit to ALU. It should maximize performance and reduce costs as well as power consumption.The different components in the Computer System Architecture are Input Unit, Output Unit, Storage Unit, Arithmetic Logic Unit, Control Unit etc.Ī diagram that shows the flow of data between these units is as follows − A computer system is basically a machine that simplifies complicated tasks.
