Tools to determine algorithm selection
It is definitely not easy to select the algorithm that is best suited for your data and your challenge. Luckily, the market is beginning to recognize that in order to move forward, tools need to exist to help with algorithm selection. How do you choose the right model? It is a difficult problem. While overfitting may be one problem, a more serious problem is that models lose accuracy over time. Therefore, you have to continuously retrain the model as the data changes. Selecting the right algorithm can be best accomplished by automating the selection of an algorithm. Take the example of a classification algorithm. There are as many as 40 different classifier algorithms. These different algorithms can be combined depending on the approach the data scientist is using. Therefore, you can have hundreds of combinations to choose from. If your data scientists need to test for potentially valid algorithms, it could take a long time to pick the best ones. Using an automation tool enables your scientists to more quickly determine the best combination of algorithms that will provide the highest score and the best fit for your data. Automation tools are important not just because of the complexity of the algorithms but also because you have to make sure that the algorithms you select to build your models will not impact data latency and data consistency.
Approaching tool selection
A variety of open-source tools are intended to help data scientists select the right algorithm. These tools are often tied directly to the language (Python, R, Java, and so on) being used. Why should data scientists use tools for algorithm selection? Many different machine learning models may all be useful in solving problems. If a data scientist can experiment with different algorithms, he will be able to improve the ability of models to predict outcomes and create models that will scale.
