How To Handle Data Files For Machine Learning
September 20, 2017
Machine learning has helped many companies and organizations to understand data and make logical decisions from it. According to seasoned Apache Spark developers, the artificial intelligence (AI) is applied to the system to automate the processes of understanding and interpreting data. As advice, these experts remind IT handlers that, data files are the most crucial in machine learning. Therefore, this calls for a need to handle them in a specific way. Below are insights on how to handle these files.
Working with small samples
Some organizations handle large data and working on all of them at the same time is practically impossible. When introducing a new working model, it is recommended that you pick random samples and work on them as the trial sample. When all the problem is solved, now the solution can be applied to all other data. Further, the habit of picking data at random is a good spot check on the system.
Assign data more memory on the application
One of the limiting factors in machine learning is default memory to the data and library files. It is hardly enough for most organizations. So, what is the best thing to do? Well, some applications will allow the users to expand the memory as a parameter when launching the program. Check if it is possible to configure the memory and expand it.
Add memory to your computer
Adding more space on your computer enhances the speed and reduces the chances of losing data through incomplete processes. Adding more memory on your computer one of the best ways to do this. Further, you can use the cloud technology to acquire more space.
Changing the data format
Are you wondering why you need to change the data format? Some data files like CSV files use the raw ASCII text which is slow in loading. To make the loading fast, you need to change the format of the files to one which is fast. A binary format like Net CDF will do a better job when it comes to speed and use of less memory.
Use of relational database
The capability of this option is limitless. It helps in accessing and storing of big data sets in an organization through progressively feeding it in batches from a disk. Database tools like MySQL are perfect examples and are compatible with many machine learning tools.
Use progressive loading or streaming of data
According to big data experts, you do not need to have all the data in the memory at the same time. It can be programmed to load progressively in batches. If not, it can also stream as needed to avoid overloading the memory of the tool to execute commands. Use of algorithms which allow streaming capability is necessary.
Using the big data platform
Platforms which are designed to handle very large data will come in handy sometimes. When the need comes, do not hesitate to take advantage of the machine learning algorithms in it. Hadoop and Spark fall on top of this category and can be applied in many instances. However, this should be the last option when all other ways of handling big data are not possible.
