dpm-coursework's Issues

Currently cannot reach to the binder server

Can you have a check please? Thanks

residual_tensor has moved to utils\generation

Expected Behaviour

In Section 3, expect to import residual_tensor from hottbox.core.

Current Behaviour

Fails to import residual_tensor.

Steps to Reproduce

from hottbox.core import residual_tensor

Additional context

Solve: residual_tensor is now in hottbox.utils.generation.
Change to : from hottbox.utils.generation import residual_tensor

Repeated work in assngments

For Q1&Q2 in assignment2 of module 3:

1.Use multi-linear rank equal to (50, 50, 2) in order to obtain Tucker representations of images of the car and apple. Analyse results by visually inspecting their reconstructions.

2.Use multi-linear rank equal to (50, 50, 2) in order to obtain Tucker representations of images of the apple taken from the top and from the side. Analyse results by visually inspecting their reconstructions.

I think these 2 questions overlap?

Thank you

Tensor mode indexing

For the above assignment in tensor unfolding, do you mean A.unfold(mode=1) or mode-2 unfolding ( A.unfold(mode=2))?

Residual_tensor import error

The residual_error function provided by the Hottbox library moved from:
hottbox.core
to
hottbox.utils.generation

Steps to Reproduce

1. Run imports for Part 3

Cannot run the project on mac

Cannot run the bash script on mac

Expected Behaviour

project starts and works

Current Behaviour

Unclear assignment instruction

For Q3 in Assignment 1 of module 2:

3. For a 3-rd order tensor that consists of 500 elements, provide three different Kruskal representations.

Does that mean those three different Kruskal representations represent the same tensor satisfying the constraints?

Thank you

Inconsistent definition of slice and fiber

Hi!

For the following definition of fiber and slice, the code example seems to be inconsistent with the description above.

For example, for mode-2 fiber, shouldn't the correct indexing be [0,:,1]?
