I wanted to learn more, so I turned to the IE Data Science Bootcamp to gain a thorough understanding of both the technical and mathematical foundations of data science.<\/p>\n<p>The third week of the bootcamp can be summarized as an <strong>ever-increasing accumulation of data-driven brain teasers.<\/strong> In our R coding course, we\u2019re preparing for our second exam at the end of the week. While our tasks are becoming more complex, we\u2019ve studied a number of packages from the tidyverse, as well as faster and more nimble data tables that will help us tackle future challenges.<\/p>\n<p>In Python, we wrote our first exam on Monday. Naturally, we were all thrilled\u2026 But in the end it was a positive experience! As the exam included random walks and simple digital image processing, it aligned well with the overall theme of the week. This was definitely a tough exam. Now, we\u2019re leaving NumPy behind and moving on to pandas, <strong>the heart of data manipulations in Python.<\/strong><\/p>\n<p><strong>Our Math &amp; Stats course continues to be highly interesting.<\/strong> We\u2019ve come across our first two touchpoints with machine learning algorithms: association rules and naive Bayes. By studying these areas, we\u2019re already catching a glimpse of the more advanced machine learning concepts that lie ahead.<\/p>\n<p>Finally, <strong>Javier Tejedor, a machine learning specialist at Endesa (a Spanish energy giant),<\/strong> spoke to us in this week\u2019s Master Class. We discussed various machine learning approaches in the context of fraud detection. His practical insights into the world of data science and his presentation on code, deep neural networks and gradient boosting on decision trees impressed everyone.<\/p>\n<p>Before beginning the bootcamp, I was skeptical about how much I could really pick up in such a short amount of time. Thanks to the immersive nature of the program, the committed instructors and my phenomenal fellow bootcampers,<strong> I\u2019m amazed at how much we\u2019ve already learned in just a few weeks.<\/strong><\/p>\n<p>I can\u2019t wait to see what\u2019s next in the bootcamp!<\/p>\n<p>Best,<\/p>\n<p>Konrad<\/p>\n<p><em>Interested in learning more about our Data Science Bootcamps?\u00a0<a href=\"https:\/\/www.ie.edu\/exponential-learning\/programs\/immersive-learning\/data-science-bootcamp\/\">Click here<\/a>!<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Hi everyone!
