What’s in a Text Analysis tool?

If you ask five different people, “What does a Text Analysis tool do?”, it is very likely you will get five different responses. The term Text Analysis is used to cover a broad range of tasks that include identifying important information in text: from a low, structural level to more complicated, high-level concepts. Included in this very broad category are also tools that convert audio to text and perform Optical Character…

Choosing Machine Learning Models

As we have discussed previously, machine learning approaches to modeling are just that – approaches. There are many forms of models we could use with machine learning, each with different design philosophies and quirks. When setting out to use machine learning to create your own models, a question you may be asking yourself is: Which model framework do I choose? From Neural Networks, to Support Vector Machines, to Decision Trees,…

The Balance between Data Redaction and Data Utility

Our personal data is a highly valuable commodity to a variety of businesses and agencies. This information is collected for a variety of reasons, and while some of the data can be fairly generic, other information—like surnames, birth dates, social security numbers, and account numbers—is more intimately linked with a person’s identity. In the wrong hands, this data can be exploited for nefarious purposes. As a result, there is a…

What’s the News with Neural Networks?

There are many reasons for the explosion of machine learning advancements over the past decade. We now have vastly improved hardware for fast computation, and memory is cheaper than ever. Data is now “Big Data,” and it is both jealously hoarded and publicly available in repositories such as ImageNet. Individually, these advancements are already a blessing for the technology-space. But for artificial intelligence (AI), they have opened the gates for…
