Abstract :Today, Big Data and Deep Learning concepts are the most frequently studied subjects. The coexistence of the concept of Deep Learning, which is another technology that emerged after the study of large data, has been a topic of revelation. Because the experience obtained due to the excess and the size of the data examined is expected to be used more quickly and efficiently by using Deep Learning technology. In this study, the concepts of Big Data and Deep Learning will be explained and some applications will be mentioned. Keywords : Deep Learning, Big Data, ESA
