In the business world, decision trees are often used to develop insights and predictions about downsizing or expanding, changing a pricing model or succession planning. The performance of a machine learning model is primarily dependent on the predictive accuracy of its training dataset with respect to the outcome of interest. If you were able to know everything about a system (quantum physics aside) you would be able to perfectly predict its future state. In reality most datasets contain a small subset of information about a system – but that is often more than enough to build a valuable ML model. That said, adding in additional data can often help improve predictive performance.

Popular techniques include self-organizing maps, nearest-neighbor mapping, k-means clustering and singular value decomposition. These algorithms are also used to segment text topics, recommend items and identify data outliers. Analyzing data to identify patterns and trends is key to the transportation industry, which relies on making routes more efficient and predicting potential problems to increase profitability. The data analysis and modeling aspects of machine learning are important tools to delivery companies, public transportation and other transportation organizations. When choosing between machine learning and deep learning, consider whether you have … Read More

Fueled by the massive amount of research by companies, universities and governments around the globe, machine learning is a rapidly moving target. Breakthroughs in AI and ML seem to happen daily, rendering accepted practices obsolete almost as soon as they’re accepted. One thing that can be said with certainty about the future of machine learning is that it will continue to play a central role in the 21st century, transforming how work gets done and the way we live. Actions include cleaning and labeling the data; replacing incorrect or missing data; enhancing and augmenting data; reducing noise and removing ambiguity; anonymizing personal data; and splitting the data into training, test and validation sets. While a lot of public perception of artificial intelligence centers around job losses, this concern should probably be reframed. With every disruptive, new technology, we see that the market demand for specific job roles shifts.

Supervised learning algorithms can be further subdivided into regression and classification. In supervised tasks, we present the computer with a collection of labeled data points called a training set (for example a set of readouts from a system of train terminals and markers where they had delays in the last three months). … Read More
