(MH): The challenge here is to restrict me to five people only. You can now easily access the dataset list on kaggle with the command!kaggle datasets list -s massachusetts. How To Have a Career in Data Science (Business Analytics)? INTRODUCTION: The Ames Housing dataset was compiled by Dean De Cock and is commonly used in data science education, it has 1460 observations with 79 explanatory variables describing (almost) every aspect of residential homes in Ames, Iowa. He has already won 3 Gold Medal Competitions this year. Some datasets also have call-to-actions, tasks, inspiration, and prizes. These kinds of competition offer problems which are more experimental than competitive problems. My first post in the discussion section was “Help me start with Kaggle!”. This is certainly not what you’d want. The first is a binary classification problem with very imbalanced target classes, as it is commonly found in fraud detection or similar contexts. The data has missing values and other issues that need to be dealt with in order to run regressions on it. My code for this project can be found here.. Imputation The main reason is reproducibility: adapting your existing ggplot2 code to new or related data is made just as simple as interpreting and explaining your insights based on the visualization choices you made. These courses are such that they train you to apply your domain knowledge to practical data. This is the fastest way to become a data scientist and improve your skills. One simple example of this competition is Digit Recognizer. The challenge here is to work methodically, and don’t get sidetracked by new ideas. Let me know in the comments section below! The dataset is very valuable as it can be used to answer the following questions: Create a classification model that uses text data features and meta-features and predict which job description are fraudulent or real. The reusability of visuals is high, which means that your past work can serve as an adaptable starting point for new projects. I don’t recall that there was a single, main source of knowledge; although I still think that the scikit-learn documentation is a pretty thorough (and underrated) way to get started. So you have started your machine learning/data science course. For instance, geospatial data often looks best on maps. This is the official account of the Analytics Vidhya team. Especially when we advocate for working on data science projects in ‘How to Become a Data Scientist in 2020’, you should always be on the lookout for interesting datasets that you could experiment on.
