Über den Kurs

If you want to break into competitive data science, then this course is for you! Participating in predictive modelling competitions can help you gain practical experience, improve and harness your data modelling skills in various domains such as credit, insurance, marketing, natural language processing, sales’ forecasting and computer vision to name a few. At the same time you get to do it in a competitive context against thousands of participants where each one tries to build the most predictive algorithm. Pushing each other to the limit can result in better performance and smaller prediction errors. Being able to achieve high ranks consistently can help you accelerate your career in data science. In this course, you will learn to analyse and solve competitively such predictive modelling tasks. When you finish this class, you will: - Understand how to solve predictive modelling competitions efficiently and learn which of the skills obtained can be applicable to real-world tasks. - Learn how to preprocess the data and generate new features from various sources such as text and images. - Be taught advanced feature engineering techniques like generating mean-encodings, using aggregated statistical measures or finding nearest neighbors as a means to improve your predictions. - Be able to form reliable cross validation methodologies that help you benchmark your solutions and avoid overfitting or underfitting when tested with unobserved (test) data. - Gain experience of analysing and interpreting the data. You will become aware of inconsistencies, high noise levels, errors and other data-related issues such as leakages and you will learn how to overcome them. - Acquire knowledge of different algorithms and learn how to efficiently tune their hyperparameters and achieve top performance. - Master the art of combining different machine learning models and learn how to ensemble. - Get exposed to past (winning) solutions and codes and learn how to read them. Disclaimer : This is not a machine learning course in the general sense. This course will teach you how to get high-rank solutions against thousands of competitors with focus on practical usage of machine learning methods rather than the theoretical underpinnings behind them. Prerequisites: - Python: work with DataFrames in pandas, plot figures in matplotlib, import and train models from scikit-learn, XGBoost, LightGBM. - Machine Learning: basic understanding of linear models, K-NN, random forest, gradient boosting and neural networks.

Top Kagglers gently introduce one to Data Science Competitions. One will have a great chance to learn various tips and tricks and apply them in practice throughout the course. Highly recommended!

Really excellent. Very practical advice from top competitors. This specialization is much more information-dense than most machine learning MOOCs. You really get your money's worth.

Really great course learned a lot. The only reason that I did not give 5 stars is that the task in some assignments could be explained somewhat clearer (would have saved me a lot of time) and especially also the scope of the final project. In hintsight after reviewing others, i spend way too much time :P

Bon cours qui permet d'aller plus loin dans son apprentissage du machine learning.

Je regrette qu'il n'y ait pas plus de travaux pratiques sur différents datasets qui nécessiteraient différentes approches (on travaille essentiellement sur le même dataset avec des techniques de plus en plus évoluées).

Some of the stuff is really great! I learned a lot. Thanks. On the other hand, there are some bugs in the codes provided, specially in the additional assignment in week 3. Bugs in the online assignment grader and so on... without the bugs I would have rated this 5 stars.

It's a very challenging course. You need strong basics of Machine Learning and programming in Python. The topics are very useful to learn how to improve your models. Nevertheless, there is no support in the forums from tutors.

Great course. Very challenging. My only real complaint is about the limitations on the frequency of final project submission (even if the submission is ungraded for any reason) which are a little unreasonable.

Very good course for intermediate to the advanced level group. It covers various number of models and practical approach which can be used in Competitions in the Kaggle and also in a real-world problem.

The course has many useful topics but needs updating. There are things not well explained while the final assignment is more of a riddle to find how to pass the exam than making an advanced model.

Great course, but assignments need a bit more clarity in instructions. I had a really hard time trying to figure out the last programming assignment in this course.

Very good course, this is a advance course.

You must integrate with external documentation but this course give a lot of a good points.
