Converting (reverse-engineering) Turing machine into program or most concise algorithm?

It is known that every program or every algorithm can be converted to Turing machine. But what about the reverse process? Is there algorithm (or research trend that considers such algorithm) to convert some Turing machine into algorithm as expressed in some high level programming language (e.g. in Algol, Java, Prolog, Haskell)? The comprehensiveness/conciseness or … Read more

What does “Temporal extent” mean?

I am reading Long-term Temporal Convolutions for Action Recognition and under the Section 3.1, I read this: To investigate the impact of long-term temporal convolutions, we here study network inputs with different temporal extents….. and then As illustrated in Figure 2, the temporal resolution in our 60f network corresponds to 60, 30, 15, 7 and … Read more

Value flow (and economics) in stacked reinforcement learning systems: agent as reinforcement environment for other agents?

There is evolving notion of stacked reinforcement learning systems, e.g. https://www.ijcai.org/proceedings/2018/0103.pdf – where one RL systems executes actions of the second RL system and it itself executes action of the thrid and the reward and value flows back. So, one can consider the RL system RLn with: S – space of states; A={Ai, Ainner, Ao} … Read more

Why do we need to change the (weight decay) regularization parameter when changing the number of inputs that neural network is being trained with?

I am currently working my way through Michael Nielsen’s ebook Neural Networks and Deep Learning and I am reading about overfitting and (L2) regularization. In this subsection, the process of L2 (a.k.a weight decay) regularization is introduced as being the process of adding the term λ2n∑w2 to the cost function so that it becomes C=C0+λ2n∑w2 … Read more

How can Kneser-Ney Smoothing be integrated into a neural language model?

I found a paper titled Multimodal representation: Kneser-Ney Smoothing/Skip-Gram based neural language model. I am curious about how the Kneser-Ney Smoothing technique can be integrated into a feed-forward neural language model with one linear hidden layer and a softmax activation. What is the purpose of the Kneser-Ney in such a neural network, and how can … Read more

How can one measure the time dependency of an RNN?

Most of the discussion about RNN and LSTM alludes to the varying ability of different RNNs to capture “long term dependency”. However, most demonstrations use generated text to show the absence of long term dependency for vanilla RNN. Is there any way to explicitly measure the time dependency of a given trained RNN, much like … Read more

Which features can be considered for neural network based SAT solving?

I’m trying to implement SAT solver, based on backtracking algorithm and BCP. This SAT solver is trying to pick one literal from each clause, from 3-CNF SAT instances. I’ve implemented a neural network based heuristic to pick valid literal at first, and degree of how valid is given literal from clause is determined by neural … Read more
