Specialist in Data Science / Machine Learning

Assigment Part 8 - Joanna Gajewska

  • „While working on data science assignments my main goal is extracting meaning from and interpret data. For this I use tools and methods from statistics and machine learning as well as software engineering skills. 
  • First I spent time in the process of collecting, cleaning, and munging data. Once I get the data into shape, I  do exploratory data analysis. This includes finding patterns, building models, and algorithms - some with the intention of understanding product usage and the overall health of the product, and others to serve as prototypes that ultimately get baked back into the product. I also design experiments since it is a critical part of data-driven decision making. In my work communicating with team members, engineers, and leadership in clear language and with data visualizations is essential so that even if my clients are not immersed in the data themselves, they will understand the implications.”
  • Below you may find some examples of my work (pdf files):
Business and the meaning of machine learning
11 September 2021
Machine learning is a wide term and it covers two disciplines: one discipline is machine learning research, another discipline is applied machine learning. Business should have a good understanding of the difference between these two, otherwise it might fail hiring people with wrong skills and setting wrong expectations. Machine learning

Programming Languages for Data Science
08 September 2021
…Programming is one of the essential skills for a data scientist apart of statistics and linear algebra. There are several data science programming languages. Currently the most popular ones are R, Python and SQL.  Python is very much recommended for programming beginners, since it is easy to learn, it has

How To Approach A Machine Learning Project
06 May 2021
...Machine learning is an analytical way of solving problems through identification, classification or prediction. Algorithms learn from entered data and then use this knowledge to draw conclusions from new data. Machine learning is a branch within artificial intelligence that uses mathematical algorithms that allow machines to learn.... For more information,
