Acerca del Curso

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!

This course is fantastic. It's chock full of practical information that is presented clearly and concisely. I would like to thank the team for sharing their knowledge so generously.

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.

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.

Lots of useful information, but far from what you need to win a data science competition. So i suggest the title be changed to "Basics to start learning how to compete in a Kaggle competition.- Learn by PAST top Competitors" . As they will not help you at all in current competitions, only what they have done in the past, which is of public knowledge already.

Very interesting, original and revealing materials and tricks to tackle competitive machine learning more efficiently.

Sadly, teaching is quite poor and shallow, focusing on personal examples and "I did that and it just worked"-type of experiences that introduce more noise rather than clearing the way to a full understanding of issues during ML competitions (this also includes practical examples).

I guess in a second version and after a review on the teaching methods, this course could be easily a must for ML engineers on the making.

Content is interesting but language is very difficult to understand and due to that fact the course was not engaging for me.

a little too difficult for new pandas learner, some quizzes are confusing, the reply from the teachers is slow.

Si bien los instructores tienen mucha experiencia en Kaggle, no me resultó muy util a la hora de aprender Data science para un entorno empresarial y por proyectos. Si tu objetivo es dedicarte a estas competencias te lo recomiendo, pero como parte de una especialización en ciencia de datos, No.

Very dry presentation. Video is not a good medium for this material.
