Study Notes
Machine Learning Life Cycle
- The machine learning life cycle consists of 7 steps: Gathering Data, Data Preparation, Data Wrangling, Data Analysis, Train Model, Test Model, and Deployment.
Gathering Data
- The first step of the machine learning life cycle, aiming to identify and obtain all data-related problems.
- Data can be collected from various sources such as files, databases, the internet, or mobile devices.
- The quantity and quality of the collected data will determine the efficiency of the output.
Data Preparation
- Exploring, organizing, and preparing the data for use in machine learning training.
- Understanding the nature of data, including characteristics, format, and quality.
- Identifying correlations, general trends, and outliers.
Data Wrangling (Cleaning)
- The process of cleaning and converting raw data into a usable format.
- Common issues with collected data include missing values, duplicates, invalid data, and noise.
- Various filtering techniques are used to clean the data.
Data Analysis
- Using cleaned and prepared data to select a machine learning technique (model) such as Classification, Regression, Cluster analysis, or Association.
- Building and evaluating the model using the prepared data.
- Reviewing the results of the model.
Train Model
- Training the model to improve its performance using various machine learning algorithms.
- The model is trained on datasets to understand patterns, rules, and features.
Test Model
- Testing the model to check for accuracy by providing a test dataset.
- Determining the percentage accuracy of the model as per the project or problem requirement.
Deployment
- The final step of the machine learning life cycle, where the model is deployed in a real-world system.
