Update codes from Tensorflow 1.0 to 2.0 - Road Taken 529 0
Started by Patrick Ng
If you are, like me, have bunch of deep neural network (DNN) Tensorflow 1.0 (tf.1) codes that served their purpose, but now want to run on GPU and perform more experiments faster, then the following may help save a weekend (rather than banging head tracking down barrage of error messages). Issue - Tensorflow 2 (tf.2) supports GPU but is not backward compatible (tf.1 codes won't run as is). Lesson 1 - upgrade from tf.1 to tf.2 (i.e., completed installation), the first roadblock is that plac...

Energy in Data 2022 - Tackling the Challenges 518 0
Started by Patrick Ng
The first in-person (after debut 2019) Energy in Data event Austin Feb 21 - 23, 2022 was a productive endeavor. Of particular interest to this community is the data-centric challenges identified by the participants in breakout sessions at the end of each day. Instead of happy hour, EiD had working breakouts so we could dive in, generate deeper and richer experience. See summary table below. Call for volunteers - anyone interested in helping us crack the 'code' tack...

Image Segmentation Algo applied to Surface Wave Dispersion and S-wave Inversion 464 0
Started by Patrick Ng
Saw a practical example using open source DeepLab V3 applied to transformed surface wave data (i.e., in frequency-wavenumber and Radon domain), followed by inversion to derive the subsurface shear-wave velocity structure. Takeaway Automated 'picking' of dispersion curves in appropriate feature-engineering space, using deep learning algo can minimize the pain points out of data prep and processing (otherwise time-consuming and labor-intensive). Possibility DeepLab next-gen can be...
