Teacher:In this task, you are given the abstract of a research paper. Your task is to generate a summary of this abstract. Your summary should not be very short, but it's better if it's not more than 30 words.
Teacher: Now, understand the problem? Solve this instance: We consider the learning of algorithmic tasks by mere observation of input-output
pairs. Rather than studying this as a black-box discrete regression problem with
no assumption whatsoever on the input-output mapping, we concentrate on tasks
that are amenable to the principle of divide and conquer, and study what are its
implications in terms of learning.
This principle creates a powerful inductive bias that we leverage with neural
architectures that are defined recursively and dynamically, by learning two scale-
invariant atomic operations: how to split a given input into smaller sets, and how
to merge two partially solved tasks into a larger partial solution. Our model can be
trained in weakly supervised environments, namely by just observing input-output
pairs, and in even weaker environments, using a non-differentiable reward signal.
Moreover, thanks to the dynamic aspect of our architecture, we can incorporate
the computational complexity as a regularization term that can be optimized by
backpropagation. We demonstrate the flexibility and efficiency of the Divide-
and-Conquer Network on several combinatorial and geometric tasks: convex hull,
clustering, knapsack and euclidean TSP. Thanks to the dynamic programming
nature of our model, we show significant improvements in terms of generalization
error and computational complexity.
Student:
Dynamic model that learns divide and conquer strategies by weak supervision.
