Main course dsci¶
https://www.kaggle.com/learn/intro-to-machine-learning:
1 How Models Work: The first step if you’re new to machine learning
2 Basic Data Exploration: Load and understand your data
3 Your First Machine Learning Model: Building your first model. Hurray!
4 Model Validation: Measure the performance of your model ? so you can test and compare alternatives
5 Underfitting and Overfitting: Fine-tune your model for better performance.
6 Random Forests: Using a more sophisticated machine learning algorithm.
https://www.kaggle.com/learn/intermediate-machine-learning:
2 Missing Values: Missing values happen. Be prepared for this common challenge in real datasets.
3 Categorical Variables: There’s a lot of non-numeric data out there. Here’s how to use it for machine learning
4 Pipelines: A critical skill for deploying (and even testing) complex models with pre-processing
5 Cross-Validation: A better way to test your models
6 XGBoost: The most accurate modeling technique for structured data
7 Data Leakage: Find and fix this problem that ruins your model in subtle ways
https://www.kaggle.com/learn/data-visualization:
2 Line Charts: Visualize trends over time
3 Bar Charts and Heatmaps: Use color or length to compare categories in a dataset
4 Scatter Plots: Leverage the coordinate plane to explore relationships between variables
5 Distributions: Create histograms and density plots
6 Choosing Plot Types and Custom Styles: Customize your charts and make them look snazzy
https://www.kaggle.com/learn/pandas:
1 Creating, Reading and Writing: You can’t work with data if you can’t read it. Get started here.
2 Indexing, Selecting & Assigning: Pro data scientists do this dozens of times a day. You can, too!
3 Summary Functions and Maps: Extract insights from your data.
4 Grouping and Sorting: Scale up your level of insight. The more complex the dataset, the more this matters
5 Data Types and Missing Values: Deal with the most common progress-blocking problems
6 Renaming and Combining: Data comes in from many sources. Help it all make sense together
https://www.kaggle.com/learn/feature-engineering:
1 Baseline Model: Building a baseline model as a starting point for feature engineering
2 Categorical Encodings: There are many ways to encode categorical data for modeling. Some are pretty clever.
3 Feature Generation: The frequently useful case where you can combine data from multiple rows into useful features
4 Feature Selection: You can make a lot of features. Here’s how to get the best set of features for your model.
