Learning Approximate Distribution-Sensitive Data Structures
We present a computational model of mental representations as data-structures which are distribution sensitive, i.e., which exploit non-uniformity in their usage patterns to reduce time or space complexity. Abstract data types equipped with axiomatic specifications specify classes of concrete data structures with equivalent logical behavior. We extend this formalism to distribution-sensitive data structures with the concept of a probabilistic axiomatic specification, which is implemented by a concrete data structure only with some probability. We employ a number of approximations to synthesize several distribution-sensitive data structures from probabilistic specification as deep neural networks, such as a stack, queue, natural number, set, and binary tree.
A method for training neural networks to mimic abstract data structures is presented. The idea of training a network to satisfy an abstract interface is very interesting and promising, but empirical support is currently too weak. The paper would be significantly strengthened if the method could be shown to be useful in a realistic application, or be shown to work better than standard RNN approaches on algorithmic learning tasks. The claims about mental representations are not well supported. I would remove the references to mind and brain, as well as the more philosophical points, or write a paper that really emphasizes one of these aspects and supports the claims.

Learning Approximate Distribution-Sensitive Data Structures
We present a computational model of mental representations as data-structures which are distribution sensitive, i.e., which exploit non-uniformity in their usage patterns to reduce time or space complexity. Abstract data types equipped with axiomatic specifications specify classes of concrete data structures with equivalent logical behavior. We extend this formalism to distribution-sensitive data structures with the concept of a probabilistic axiomatic specification, which is implemented by a concrete data structure only with some probability. We employ a number of approximations to synthesize several distribution-sensitive data structures from probabilistic specification as deep neural networks, such as a stack, queue, natural number, set, and binary tree.

<think>Okay, to do a decent peer review, I should start with summarizing what the work is about. This includes novelty, contributions, clarity, and impact. I might include suggestions to issues that I find critical to the usefulness of the work. Starting with novelty, there are different types of novelty. The first aspect of novelty is scope and scale. Is the work covering a broader perspective than previous works? The second aspect is methodology. Is the proposed methodology novel compared to previous methods? Do they provide any significant advantage over previous methodologies? The third aspect is results. Are the results different compared previous work? Does this lead to any novel theories or an extension of current theories? Next is clarity, I will be reading the work in depth and analyze if any sentences can be potentially ambiguous or misleading. If any sentences are ambiguous, I will state them and give a suggestion on how to rephrase such sentence or how to make more clear to the audience. Lastly, impact is important. I will attempt to predict how such work will impact the scientific community. This might include the applications of such work and how the work might transform the way we study a certain topic. Finally, I will might only mention issues that are critical. This is to keep the review as concise and helpful as possible.</think>
