Hi Jason,
Thanks for the response! The 3D tensor is because there are (or will be) multiple postal codes and each character of the postal code is encoded. Here’s a clearer example:
[
	[ 
		[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 1 ], // 9
		[ 0, 0, 0, 0, 1, 0, 0, 0, 0, 0 ], // 4
		[ 0, 0, 0, 0, 0, 0, 0, 1, 0, 0 ], // 7
		[ 1, 0, 0, 0, 0, 0, 0, 0, 0, 0 ], // 0
		[ 0, 1, 0, 0, 0, 0, 0, 0, 0, 0 ] // 1
	], [ 
		[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 1 ], // 9
		[ 0, 0, 0, 0, 1, 0, 0, 0, 0, 0 ], // 4
		[ 0, 1, 0, 0, 0, 0, 0, 0, 0, 0 ], // 1
		[ 1, 0, 0, 0, 0, 0, 0, 0, 0, 0 ], // 0
		[ 0, 0, 1, 0, 0, 0, 0, 0, 0, 0 ] // 2
	],
	...
]

Hopefully that makes sense. From your response, sounds like this could be a 2D tensor however, yeah? If I normalize the time of day data to match the postal code data, I could do something like:
[
	[ 
		[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 1 ], // 9
		[ 0, 0, 0, 0, 1, 0, 0, 0, 0, 0 ], // 4
		[ 0, 0, 0, 0, 0, 0, 0, 1, 0, 0 ], // 7
		[ 1, 0, 0, 0, 0, 0, 0, 0, 0, 0 ], // 0
		[ 0, 1, 0, 0, 0, 0, 0, 0, 0, 0 ], // 1
		[ 0, 0, 1, 0, 0, 0, 0, 0, 0, 0 ] // evening
	], 
	...
]

This would be simple enough to do but feels a little dirty. But maybe that’s just how it would have to be done? I worry about how easy this will be when adding more data inputs as well. Not all data may conform so easily. Actually, another thought, as I’m working this through in my head, I think I could use your example but expand the columns for each postal code character.
[ 
	[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, // 9
	0, 0, 0, 0, 1, 0, 0, 0, 0, 0, // 4
	0, 0, 0, 0, 0, 0, 0, 1, 0, 0, // 7
	1, 0, 0, 0, 0, 0, 0, 0, 0, 0, // 0
	0, 1, 0, 0, 0, 0, 0, 0, 0, 0, // 1
	0, 0, 1, 0  ] // evening
]

Hmm, that seems like it would work well. And would support future inputs as they would continue to get tacked on to the end. Thoughts in this?
I was also wondering if I should not use the one hot encoding and simply have something like:
[ 
	[ 94701, 2 ],
	[ 94102, 1 ],
	...
]

The encoding of the postal codes has worked really well in my tests, and I haven’t tried this approach, but am curious if it could/would work.
Thanks again! I’ll check out the link, thanks for sharing!
