Attachments: Hep-Th. Lusseau, K. Schneider, O.A data set or dataset is a collection of data. In the case of tabular data, a data set corresponds to one or more database tableswhere every column of a table represents a particular variable, and each row corresponds to a given record of the data set in question.
The data set lists values for each of the variables, such as height and weight of an object, for each member of the data set. Each value is known as a datum. Data sets can also consist of a collection of documents or files. In the open data discipline, data set is the unit to measure the information released in a public open data repository. The European Open Data portal aggregates more than half a million data sets. Some other issues real-time data sources,  non-relational data sets, etc.
Several characteristics define a data set's structure and properties. These include the number and types of the attributes or variables, and various statistical measures applicable to them, such as standard deviation and kurtosis. The values may be numbers, such as real numbers or integersfor example representing a person's height in centimeters, but may also be nominal data i.
More generally, values may be of any of the kinds described as a level of measurement. For each variable, the values are normally all of the same kind. However, there may also be missing valueswhich must be indicated in some way. In statisticsdata sets usually come from actual observations obtained by sampling a statistical populationand each row corresponds to the observations on one element of that population.
Data sets may further be generated by algorithms for the purpose of testing certain kinds of software. Some modern statistical analysis software such as SPSS still present their data in the classical data set fashion. If data is missing or suspicious an imputation method may be used to complete a data set.

In this post you will discover a database of high-quality, real-world, and well understood machine learning datasets that you can use to practice applied machine learning. If you are interested in practicing applied machine learning, you need datasets on which to practice. I teach a top-down approach to machine learning where I encourage you to learn a process for working a problem end-to-end, map that process onto a tool and practice the process on data in a targeted way.
I recommend you select traits that you will encounter and need to address when you start working on problems of your own such as:. You can create a program of traits to study and learn about and the algorithm you need to address them, by designing a program of test problem datasets to work through.
UCI Source Code Data Sets
For beginners, you can get everything you need and more in terms of datasets to practice on from the UCI Machine Learning Repository. For more than 25 years it has been the go-to place for machine learning researchers and machine learning practitioners that need a dataset.
Each dataset gets its own webpage that lists all the details known about it including any relevant publications that investigate it. For example, here is the webpage for the Abalone Data Set that requires the prediction of the age of abalone from their physical measurements. Take a look at the repository homepage as it shows featured datasets, the newest datasets as well as which datasets are currently the most popular.
I would advise you to think about the traits in problem datasets that you would like to learn about. These may be traits that you would like to model like regressionor algorithms that model these traits that you would like to get more skillful at using like random forest for multi-class classification.
I have listed one dataset for each trait, but you could pick different datasets and complete a few small projects to improve your understanding and put in more practice. For each problem, I would advise that you work it systematically from end-to-end, for example, go through the following steps in the applied machine learning process:. Select a systematic and repeatable process that you can use to deliver results consistently.
It allows you to build up a portfolio of projects that you refer back to as a reference on future projects and get a jump-start, as well as use as a public resume or your growing skills and capabilities in applied machine learning. Pick a tool or platform like Weka, R or scikit-learn and use this process to learn a tool. Cover off both practicing machine learning and getting good at your tool at the same time.
Use Weka. It has a graphical user interface and no programming is required. I would recommend this to beginners regardless of whether they can program or not because the process of working machine learning problems maps so well onto the platform.
With a strong systematic process and a good tool that covers the whole process, I think that you could work through a problem in one-or-two hours. This means you could complete one project in an evening or over two evenings. You choose the level of detail to investigate and it is a good idea to keep it light and simple when just starting out.
The dataset pages provide some background on the dataset. Often you can dive deeper by looking at publications or the information files accompanying the main dataset. I have little to no experience working through machine learning problems. Now is your time to start. Pick a systematic processpick a simple dataset and a tool like Weka and work through your first problem. Place that first stone in your machine learning foundation.This page is a repository of various data sets we have curated in our research in large scale analysis of source code.

Many but not all of the UCI datasets you will use in R programming are in comma-separated value CSV format: The data are in text files with a comma between successive values.
A typical line in this kind of file looks like this:. This is the first line from a well-known dataset called iris. The rows are measurements of iris flowers — 50 each of three species of iris.
The species are called setosaversicolorand virginica. The data are sepal length, sepal width, petal length, petal width, and species. On an iris, sepals look something like larger petals underneath the actual petals. In that first line of the dataset, notice that the first two values sepal length and width are larger than the second two petal length and width. You can find iris in numerous places, including the datasets package in base R.
The point of this exercise, however, is to show you how to get and use a dataset from UCI. Click on the Data Set Description link.
This opens a page of valuable information about the data set, including source material, publications that use the data, column names, and more. In this case, this page is particularly valuable because it tells you about some errors in the data. Returning to the previous page, click on the Data Folder link. On the page that opens, click the iris. This opens the page that holds the dataset in CSV format. To download the dataset, you use the read. To accomplish everything at once — to use just one function to read the file into R as a dataframe complete with column names — use this code:.
The first argument is the web address of the dataset. The second indicates that the first row of the dataset is a row of data and does not provide the names of the columns. The third argument is a vector that assigns the column names. The column names come from the Data Set Description web page. That page gives class as the name for the last column, but it seems that species is correct.
You can do this still another way. In addition, he has written numerous articles and created online coursework for Lynda.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.
