For more open projects, explore the available dataset columns and select one that interests you. This will allow you to work on concrete problems and apply the skills you have acquired.
Acquire fundamental skills
Before entering complex competitions, make sure you have a good grasp of basic machine learning skills. This includes understanding and the ability to analyze fundamental concepts such as regressions, classifications, algorithms of clustering and cross-validation techniques. Kaggle offers free training (with or without certification) and notebooks that can help you strengthen these skills.
Use Kaggle notebooks
Kaggle notebooks are online coding environments where you can write and run Python code directly on the platform. They are ideal for experimenting and testing your models. Start by exploring public notebooks to see how others have addressed similar issues. Then, create your own notebooks to test your ideas and solutions. Notebooks can also be shared with the community for feedback and suggestions.
Learn by contributing and collaborating
Kaggle is an active community where learning and collaboration are key. Join forum discussions to ask questions, share knowledge, and get advice. Collaborating with other participants can simulate corporate work environments, improving your collaboration and project management skills.
Submit and refine your models
Once you've developed a model, submit it to the competition or project to get a score. Use feedback to refine and improve your model. Iteration is important in machine learning, so be ready to adjust your approaches based on the results and new information you get.
Keep up with the progress and keep learning
The field of machine learning is evolving rapidly with new techniques and tools. Stay up to date by following the latest publications, exploring new competitions, and continuing to learn through online courses and personal projects. Actively participating in the Kaggle community will help you stay informed and improve your skills.
💡 By following these steps, you can develop your machine learning skills while taking advantage of the wealth of resources and community that Kaggle offers.
What types of competitions are there on Kaggle?
On Kaggle, competitions vary according to the challenges they pose and the goals they aim for. Here are the main types of competitions that can be found on the platform:
· Forecasting competitions : These competitions focus on forecasting future values based on historical data. For example, predicting future sales of a product, energy demand, or economic trends. Time series models and regression techniques are often used.
· Classification competitions : Here, the challenge is to classify data into different categories. This may include tasks like image classification (identifying objects in photos), text classification (determining how a message feels), or tabular data classification.
· Regression competitions : These competitions aim to predict continued value. Participants should create models that can estimate quantities such as the price of a house, the amount of pollution, or financial scores.
· Anomaly detection competitions : In these competitions, the objective is to detect anomalies or unusual behaviors in data sets. This may include detecting fraud, detecting defects in manufacturing processes, or identifying erroneous data.
· Segmentation competitions : These competitions generally focus on image segmentation, where participants need to divide an image into meaningful regions or identify specific objects in an image. This is commonly used in fields such as medicine to segment medical images.
· Text generation competitions : Here, participants should generate text based on specific prompts or conditions. This includes tasks such as automatically generating text, translating, or creating responses in dialog systems.
· Research and optimization competitions : These competitions focus on solving optimization or research problems in complex spaces. Participants may be required to develop algorithms to solve logistical, planning, or resource allocation problems.
· Recommendation algorithm competitions : In these competitions, participants must create recommendation systems that can predict user preferences for articles, movies, products, etc., based on historical data.
👉 Each competition on Kaggle has specific rules and defined objectives, allowing participants to test their skills in a variety of contexts and to apply Data Science techniques to concrete problems.
