Artificial Intelligence has come a long way since the initial applications the technology was developed for, and advancements in the field yet again show another added benefit in the form of detecting COVID-19. Artificial Intelligence applications have been used to detect COVID-19 in patients and distinguish the virus from other diseases such as phenomena and other lung diseases. According to Jun Xia from Shenzhen Second People's Hospital's Department of Radiology, a learning model can be used so AI can accurately differentiate COVID-19 from different types of lung disease, while detecting whether or not one is positive for the virus as well. 

Furthermore, the use of AI is used within contact tracing models to detect where the virus is spread and how severe it is in different given areas. Applications can currently track where the virus is and algorithms are being tested to not only track the virus but also predict where it will spread as well. This not only gives us a better fighting chance against COVID-19 but future pandemics as well. 

Finally, AI and machine learning are being used to accelerate medical drug treatment for COVID-19 to identify potential medications to help act as a treatment for the virus. BenevolentAI used machine learning techniques for this purpose to deduce that Baricitinib, a drug for rheumatoid arthritis, is a strong candidate to inhibit the progression of COVID-19 and is now in clinical phases to act as a treatment as a result.

AI and machine learning have come so far in such a short amount of time, and as a result are helping us deal with real-world problems in more ways than one.

At first, test data and training data may seem like the same thing, however there are several fundamental differences between the two that can make or break your data model.

Training Data is used to build or create a model in its earlier stages and can be implemented to help the model run. Training Data is often found in machine learning to ensure the data model can be "trained" to perform several actions, and ensuring the future development of the API and algorithms that a machine will continuously work with.

Test Data on the other hand are datasets which are used to validate existing data models to make sure algorithms produce correct results, machine learning is happening correctly, and output which mirrors intended findings are consistent. Alternatively, test data can be used to invalidate a data model and disprove it's efficiency, or find that a data model or AI may be producing sub-optimal results and therefore may need further tests or different kinds of training to reach maximum efficiency. Below, is a diagram depicting the data training, validation, and testing model and the different steps that may be encompassed throughout the different processes.

​Training AI or any sort of machine learning is a rigorous process that requires a fair amount of training, validation, and testing, and it's very rare a data model is perfected on its first try. That's why it's important for training and test data to be differentiated; otherwise, results will appear too similar, leading observations and evaluations for both datasets to be inconclusive, ensuring more testing and validation would have to be done.

What Test Data is Being Used Today and by Who?

An organization’s development ecosystem, including technical partners, software development and
contractors have a growing need to access private and confidential data to do their jobs. Relevant data sources are a necessary component of the software development, technical integration, testing, implementation and ongoing operations and maintenance processes and production data sources are commonly accessed and modified for this purpose. Complex, integrated technology solutions can no longer be managed within an organization’s internal operations but requires a large and varied global ecosystem of partners, consultants, technology companies and contractors. There is a similar need for test data within the organizations cyber security operations. It is also common practice for this ecosystem to utilize historical data, captured network traffic and simple network traffic generation technology for testing purposes. 

With every new year comes exciting new updates and trends to the technological world around us! We at ExactData are excited about many trends and future advancements to come, but here are five that we're excited about in particular!

1) Advancement of AI and Mobile Intelligence
It's no secret that AI and mobile intelligence are evolving everyday. We see growth in both of these departments to no end, where things like facial recognition, fingerprint, voice, and eyes scans are all becoming more of a reliable reality! This is seen through many of the innovations of Apple, Samsung, and Google have brought to the table, but also through other fields of data science as well!

2) Automation and Innovation
When one thinks of automation and innovation, jobs and mundane tasks are often the first things thought of. How is data being innovated or automated you may ask? Well being able to derive data in faster response rates, being able to generate, switch, and use data for test purposes on the fly for exact results seems innovative to us! This innovation can be traced to artificial intelligence as well through pattern recognition, GPS sensors, self-driving cars, and more!

3) Cloud Computing and Cyber Security
Cloud computing is becoming more distributed, meaning the origin of the cloud can distribute services to other locations while operating fully in effect from one area. ​Server updates, latency checks, and bandwidth fixes are becoming quicker every year which not only affects the cloud and its functions but can also be used to stop breaches, glitches, and hackers right in their tracks as soon as they get into the system.

4) Financial Patterns and Recognition
Recognizing financial data patterns through data has been historically tricky due to the immense analytical prowess and and observational skills that could be needed. AI and statistical learning developments however can be trained to pick up these patterns more quickly than ever before, and with less error too. Financial analytics and trend recognition will certainly see upgrades in the upcoming year, especially with more variables such as cryptocurrency coming into play.

5) Accessibility and Privacy
Accessibility and privacy for data files come hand in hand; by making something more accessible you also have the means to make it more restricted. Added levels of security for data can come in many different forms; test data, artificial data, cloud computing, advanced machine learning, more advanced security protocols and more. The rule of thumb is to keep everything private that you may need for later so that nobody else can take or modify it.

While there are so many trends we believe to be up and coming in the world of data, these were just some of the few we believe to be relevant to both the industry and general public as a whole.
