My company is trying to move into machine learning & we'd love to replicate an image like this for our debut product. If anyone has an idea as to what software Uber used, that would be helpful. I've done a fair amount of blending in Illustrator, but this seems to have a 3-dimensional aspect that is tough to replicate with just the blend tool. If done in illustrator, any idea as to method would be helpful as well!
If I were producing this, I'd be working in modo, and I'd use a multi-octave noise texture (projected down the Z axis) to drive displacement of a subdivided plane; I'd feed this surface result into a procedural mesh stack in which I'd also have an array of linear polys, projected down to the surface with an intersection mesh op, and I'd set the resulting procedural mesh to take those edges and convert them to curves. I'd do it that way 'cos you can animate the noise and so animate the graph.
I learned the basics of this approach from a Pixel Fondue posting, and played with it myself and extended it a bit further for my own use, and saved out an assembly - I made a brief render animation of my results - in my case the lines are being driven not from above but from the side, to create animated topo lines.
Here's a still from that animation:

And here's the original Pixel Fondue training video:
Hope this helps.
Perhaps not the easiest and best but you could try making a group of many horisontal lines, then by using 1-point perspective grid, attach the lines to the horisontal plane. Now you can use the Swirl tool to manualy add waves.
