How To Measure ML Model Accuracy
By Bryon Moyer - 01 Apr, 2021 - Comments: 0

Machine learning (ML) is about making predictions about new data based on old data. The quality of any machine-learning algorithm is ultimately determined by the quality of those predictions. However, there is no one universal way to measure that quality across all ML applications, and that has broad implications for the value and usefulness of machine learning. “Every industry, every d... » read more

Hidden Costs In Faster, Low-Power AI Systems
By Ed Sperling - 20 Jan, 2021 - Comments: 1

Chipmakers are building orders of magnitude better performance and energy efficiency into smart devices, but to achieve those goals they also are making tradeoffs that will have far-reaching, long-lasting, and in some cases unknown impacts. Much of this activity is a direct result of pushing intelligence out to the edge, where it is needed to process, sort, and manage massive increases in da... » read more

Neural Networks Without Matrix Math
By Katherine Derbyshire - 17 Sep, 2020 - Comments: 0

The challenge of speeding up AI systems typically means adding more processing elements and pruning the algorithms, but those approaches aren't the only path forward. Almost all commercial machine learning applications depend on artificial neural networks, which are trained using large datasets with a back-propagation algorithm. The network first analyzes a training example, typically assign... » read more

Bridging Math And Engineering In ML
By Ed Sperling - 08 Jan, 2020 - Comments: 0

Steve Roddy, vice president of products for Arm’s Machine Learning Group, examines the intersection of high-level mathematics in the data science used in machine learning within area, speed, and power limitations, and how to bring these two worlds together with the least amount of disruption. » read more

The Cost Of Accuracy
By Brian Bailey - 13 Dec, 2018 - Comments: 0

How accurate does a system need to be, and what are you willing to pay for that accuracy? There are many sources of inaccuracy throughout the development flow of electronic systems, most of which involve complex tradeoffs. Inaccuracy leaves an impact on your design in ways you are not even aware of, hidden by best practices or guard-banding. EDA tools also inject some inaccuracy. As the i... » read more

How Good Is 95% Accuracy?
By Katherine Derbyshire - 28 Dec, 2017 - Comments: 0

Conventional, deterministic computers don’t make mistakes. They execute a predictable series of computations in response to any given input. The input might be mistaken. The logic behind the operations that are performed might be flawed. But the computer will always do exactly what it has been told to do. When unexpected results occur, they can be attributed to the programmer, the system manu... » read more

Accuracy Is Relative
By Ann Mutschler - 11 Aug, 2016 - Comments: 0

I've been doing some thinking on the concept of accuracy lately in my article, Does Power Analysis Need To Be Accurate? And, I’ve come to the conclusion that there isn’t a single conclusion to be had. Accuracy is very relative to the task at hand, as well as the use case, and the very specific power requirements. And maybe the focus shouldn't be always on the accuracy, but on what the chan... » read more

Standard Time And The Day Of Two Noons
By Brian Bailey - 20 Nov, 2014 - Comments: 2

Many of you know that I have a kind of fascination with dates, times and the way they have changed over time. Everyone measured time by using the sun 150 years ago, and while this may not have been highly accurate – well, who cared? Farmers got up when the sun rose and did their stuff until the sun set. Most people had no need for time and the idea of a watch would have been..well…untimely.... » read more
