Summary of approach: Our solution for Phase 1 is a gradient boosted decisiontree approach with a lot of feature engineering. We used the LightGBM library for boosted decisiontrees because it has absolute error as a built-in objective function and it is much faster for model training than similar tree ensemble based algorithms.
Commonly used technologies for data storage are the Hadoop Distributed File System (HDFS), Amazon S3, Google Cloud Storage (GCS), or Azure Blob Storage, as well as tools like Apache Hive, Apache Spark, and TensorFlow for data processing and analytics.
Predictive analytics forecast future events based on historical data; AI and ML models—such as regression analysis , neural networks and decisiontrees —enhance the accuracy of these predictions.
DecisionTreesDecisiontrees recursively partition data into subsets based on the most significant attribute values. Python’s Scikit-learn provides easy-to-use interfaces for constructing decisiontree classifiers and regressors, enabling intuitive model visualisation and interpretation.
For example, linear regression is typically used to predict continuous variables, while decisiontrees are great for classification and regression tasks. Decisiontrees are easy to interpret but prone to overfitting. predicting house prices), Linear Regression, DecisionTrees, or Random Forests could be good choices.
DVC uses external storage such as Azure blob storage, Amazon’s S3, Google cloud storage or even a basic google drive folder in order to store the version history of large data. For the sake of this walkthrough, we will choose to use a decisiontree which is a pretty basic regressor.
It offers implementations of various machine learning algorithms, including linear and logistic regression , decisiontrees , random forests , support vector machines , clustering algorithms , and more.
DecisionTrees These trees split data into branches based on feature values, providing clear decision rules. Cloud platforms like AWS , Google Cloud Platform (GCP), and Microsoft Azure provide managed services for Machine Learning, offering tools for model training, storage, and inference at scale.
Dive Deep into Machine Learning and AI Technologies Study core Machine Learning concepts, including algorithms like linear regression and decisiontrees. Familiarise yourself with cloud platforms like AWS, Google Cloud Platform , or Microsoft Azure for storing and processing large datasets.
What are the advantages and disadvantages of decisiontrees ? Have you worked with cloud-based data platforms like AWS, Google Cloud, or Azure? Then, I would use predictive modelling techniques like logistic regression or decisiontrees to identify significant predictors of churn and develop strategies to address them.
Here are some of the essential tools and platforms that you need to consider: Cloud platforms Cloud platforms such as AWS , Google Cloud , and Microsoft Azure provide a range of services and tools that make it easier to develop, deploy, and manage AI applications.
Classification techniques like random forests, decisiontrees, and support vector machines are among the most widely used, enabling tasks such as categorizing data and building predictive models. These methods can be grouped into several distinct categories based on their utility and application.
It works with various storage backends, such as AWS S3 , Google Cloud Storage , Azure blog storage , and local storage, to store datasets and model files. It enables developers to define machine learning pipelines with stages like data preprocessing, model training, evaluation, and more.
The weak models can be trained using techniques such as decisiontrees or neural networks, and the outputs are combined using techniques such as weighted averaging or gradient boosting. Boosting can help to improve the accuracy and generalization of the final model.
High variance means overfitting models with high flexibility tend to have high variance like decisiontrees. Microsoft Azure Text Summarization As part of its Text Analytics suite, Azure ’s Text Summarization API offers extractive summarization for articles, papers, or documents.
