This course delivers a hands-on, operational introduction to solving a first machine learning project in Python, guiding you to predict California house prices using real data features.
Differentiate data science and machine learning: data science is broad and business-oriented, while machine learning is technical with supervised, unsupervised, dimensionality reduction, and reinforcement learning; balance complexity and simplicity.
Learn the steps of a machine learning project: gather and explore data, prepare it by cleaning and scaling, train and test models, and present clear results with the right parameters.
Create a dedicated project folder on your desktop for the machine learning project, then download and install Anaconda and Spyder to access data science tools and launch your workflow.
Install essential python libraries to accelerate your machine learning project work. Use pip install to add packages, manage environments with conda, and consult online documentation to troubleshoot compatibility issues.
download the data from kaggle to start the project, then save the california houses dataset in your project folder and begin working with python.
Explore the spider IDE interface, including the code editor, variable explorer, and output pane. Learn to run scripts or sections and set the working directory to access data.
Import data in Spyder with pandas, load a csv into a data frame using pd.read_csv, and inspect its structure with df.info and column details to spot missing values.
Access a data frame column, convert its type to category to optimize performance, and filter houses by median value while preparing new columns for machine learning.
Explore data engineering and feature engineering by creating derived features like rooms per household and population per household, and dropping irrelevant columns to prepare data for machine learning.
Use the describe function to summarize each column's non-null counts, mean, std, min, and quartiles, flagging missing values and potential outliers to guide plots and visual inspection.
Create visualizations by generating histograms for all variables with a data frame and plotting library, set bins and figure size, then save and display; plot ocean proximity with value counts.
Explore how correlation scores reveal relationships between variables, build a correlation matrix, and visualize with a color-coded heatmap to identify strong, weak, and no relationships for preparing data before modeling.
Access the column median house value, describe its statistics, and plot a histogram to examine the distribution of the prices of the houses in California for the predicted variable.
Split data into train and test sets with train_test_split from scikit-learn, using 90/10 and random_state for reproducibility. Train on the train set, then evaluate on the unseen test set.
Clean and prepare data for modeling by handling missing values, removing outliers, and using a pipeline with median imputation, standard scaling, and one-hot encoding for categorical features like ocean proximity.
Explore how linear regression predicts numerical values by fitting a line with least squares, using coefficients for each variable, and note limits like outliers, overfitting, and train-test splits.
Apply a linear regression model in Python to predict house prices using a prepared pipeline, fit on training data, and evaluate performance on a test set.
Compute mean squared error and its square root to assess model performance, applying a pipeline with fit_transform on training data and transform on test data, using linear regression to predict.
Explore how the random forest regressor predicts numerical values by aggregating decisions from multiple trees, and how depth and tree count affect performance.
Train a random forest regressor in Python using the same code, adjust n_estimators and random_state, and evaluate with mean squared error to improve price predictions.
Apply grid search in scikit-learn to tune a random forest regressor, testing n_estimators, max_features, and max_depth with cross-validation, yielding best params and improved negative mean squared error.
Transmit your results clearly by highlighting model feature importance. Use a one-hot encoder to extract feature names and summarize features in a data frame for management.
Gather data from gold dot com, prepare it with pipelines, train linear regression and random forest models, and enhance house price prediction in California using grid search.
This course emphasizes the operational, iterative process of solving machine learning projects in two hours, highlighting data cleaning, model iteration, grid search, and continuous improvement with practical feedback.
In just 2 hours you will be able to complete a Machine Learning project from start to finish.
You will know all the steps of a Data Science project and how to carry them out in Python.
So far you have probably learned a lot about the theory of Machine Learning but you have no idea how to apply it to real life cases.
You may want to incorporate Machine Learning into your professional projects to improve your results but this seems overwhelming.
If you keep going like this, you can continue to learn about Machine Learning without going into practice and lose a lot of time. Worse, you might even get discouraged and give up all your efforts.
The real problem is that there are a lot of things to take into account in a Data Science project, from data collection, to data preparation, to the choice of model, to the optimisation of the algorithm.
The solution to all this is a clear plan with simple to follow but very powerful instructions, applicable to any Machine Learning project.
That's why I wanted to create a complete course, which details all the steps of Machine Learning projects, from start to finish, by implementing them directly in Python.
Be careful, this training is intense, many technical concepts are covered, as well as several Python libraries and functions. You need to be motivated.
You will have to carefully follow the different steps mentioned to make sure that the final result is valuable.
After completing this training, you will know how to solve a problem using Machine Learning and Python. You will discover how powerful this discipline can be.
Whenever you will be given any set of data, you will switch on your computer and start your project by following the different steps presented here. You will no longer be confused by where to start.
As you keep coding, you will remain confident in your approach because you will know where you are going.
You will have more and more ideas of how to apply it in your professional life.
In this course, you will discover the powerful technique of feature engineering.
You will learn 3 simple but powerful techniques used to explore data.
You will discover how to automate data preparation with 4 tools used by data scientists.
Finally, you will learn how to significantly improve your model, automatically, with a very robust method.
If you currently know few Machine Learning models, don't worry, I explain the intuition behind the models I use. This course is also suitable for those who only have a few basics in Python because the code is explained as we go along.
This course is a real guide for any Python Learning Machine project.
See you in the training.
See you soon,
