Machine Learning - Getting Datasets
Machine learning models are only as good as the data they are trained on. Therefore, obtaining good quality and relevant datasets is a critical step in the machine learning process. Let's see some different sources of datasets for machine learning and how to obtain them.
Public Datasets
There are many publicly available datasets that you can use for machine learning. Some of the popular sources of public datasets include Kaggle, UCI Machine Learning Repository, Google Dataset Search, and AWS Public Datasets. These datasets are often used for research and are open to the public.
Data Scraping
Data scraping involves automatically extracting data from websites or other sources. It can be a useful way to obtain data that is not available as a pre-packaged dataset. However, it is important to ensure that the data is being scraped ethically and legally, and that the source is reliable and accurate.
Data Purchase
In some cases, it may be necessary to purchase a dataset for machine learning. Many companies sell pre-packaged datasets that are tailored to specific industries or use cases. Before purchasing a dataset, it is important to evaluate its quality and relevance to your machine learning project.
Data Collection
Data collection involves manually collecting data from various sources. This can be time-consuming and requires careful planning to ensure that the data is accurate and relevant to your machine learning project. It may involve surveys, interviews, or other forms of data collection.
Strategies for Acquiring High Quality Datasets
Once you have identified the source of your dataset, it is important to ensure that the data is of good quality and relevant to your machine learning project. Below are some Strategies for obtaining good quality datasets −
Identify the Problem You Want to Solve
Before obtaining a dataset, it is important to identify the problem you want to solve with machine learning. This will help you determine the type of data you need and where to obtain it.
Determine the Size of the Dataset
The size of the dataset depends on the complexity of the problem you are trying to solve. Generally, the more data you have, the better your machine learning model will perform. However, it is important to ensure that the dataset is not too large and contains irrelevant or duplicate data.
Ensure the Data is Relevant and Accurate
It is important to ensure that the data is relevant and accurate to the problem you are trying to solve. Ensure that the data is from a reliable source and that it has been verified.
Preprocess the Data
Preprocessing the data involves cleaning, normalizing, and transforming the data to prepare it for machine learning. This step is critical to ensure that the machine learning model can understand and use the data effectively.
