Compare curves with Dynamic Time Warping

Given two curves, a baseline and a candidate curve, how do we know how similar they are to each other? In machine learning, it is common to compare the predicted values (candidate curve) of a testing set to the true values (baseline curve) by RMSE (Root Mean Square Error). By comparing RMSE values of different…

Choose Machine Learning Models With Cross Validation

Machine learning techniques (https://www.d3view.com/introduction-and-application-of-d3view-ml/) are becoming unprecedentedly popular. And it plays an important role in data analysis. It is critical to find the model that demonstrates the best performance. Intuitively, we can build a few different models with the data given and see which model gives the best score, either it being RMSE (root mean…

Workflow Provider: Execute Workflows within a Workflow

d3VIEW has a new worker called ‘Workflow Provider’ which allows us to execute other workflows we may have saved on the platform within the current one we are building and executing. This saves us time from rebuilding parts of a workflow that can be taken from an already built one. Find the ‘Workflow Provider’ worker…

Text Parameterize GUI: A Workflow Tool to Parameterize Input Files

The new ‘Text Parameterize GUI’ worker helps to create machine generated designs by providing a simple to use interface to parameterize any part of a text file. Examples of such applications include single stage Design of Experiments, Sensitivity Analyses, Multi-stage Optimization and for generic machine learning problems. Locate the ‘Text Parameterize GUI’ worker under the…

Using d3VIEW-Workflows to Build and Launch DOE Simulations

Workflows is d3VIEW’s application for streamlining complex business processes. With its capabilities, we can create and employ automated DOE studies for quicker analysis. Using the application’s new shape worker, *TEXT_PARAMETERIZE_GUI, we can set-up custom parameters for our text-based files, generate sampling points from these parameters, create simulations from the text, launch the DOE studies from…

Simlytiks Dashboards

d3VIEW’s visualization application Simlytiks® now has a new page layout called Dashboard that allows users to set-up a free-form presentation-styled page using dedicated widgets. Add custom text, images, data filters and aggregators, and Simlytiks charts as well. To better illustrate Simlytiks Dashboard capabilities, we’ll be looking at the Iris Class dataset which looks at how…

New Envelope Feature to Aid Material Selection in d3VIEW

d3VIEW supports material calibration and storage of calibrated materials in a scientific database native to d3VIEW. Once materials are stored in the database, d3VIEW supports filters to search and retrieve the materials of choice. Recently, we have been working on supporting visual selection through “Brushing” – a term often used to describe the ability to…

Interpolation methods for time series data

It is not unusual that due to various limitations, researchers can only collect limited number of samples. Meanwhile, for many analyses, we desire a higher resolution. In two-dimension case, we have X and Y coordinates of our points. We are interested in what happens in between any of the two points. We can draw a…

Battery Cycle Detection using ‘Current’ Time-series Data

Battery data have many interesting properties. One of them is cycles. When we consider the whole range of the data, there are a few of the metrics we are interested in. For example, test net capacity and energy, test cumulative capacity and energy, etc. From these transformed curves, we can obtain some metrics that help…

Test vs CAE in d3VIEW

As simulations drive a large portion of product development, reliance on test-data at critical development stages is invaluable to further our understanding of reality and assess our simulations. Among a wide variety of tests conducted today, the test-data can be broadly grouped into coupon-based (for material calibration), component based (for sub-system validation) and full-system tests.…
