Learning to Rank Normalized Entropy Curves with Differentiable Window Transformation

no code implementations25 Jan 2023 Hanyang Liu, Shuai Yang, Feng Qi, Shuaiwen Wang

We also introduce a novel differentiable indexing method for the proposed adaptive curve transformation, which allows gradients with respect to the discrete indices to flow freely through the curve transformation layer, enabling the learned window sizes to be updated flexibly during training.

Non-local Channel Aggregation Network for Single Image Rain Removal

no code implementations3 Mar 2021 Zhipeng Su, Yixiong Zhang, Xiao-Ping Zhang, Feng Qi

Second, aggregating channels could help our model to concentrate on channels more related to image background instead of rain streaks.

Maclaurin's series expansions for positive integer powers of inverse (hyperbolic) sine and related functions, specific values of partial Bell polynomials, and two applications

no code implementations26 Jan 2021 Bai-Ni Guo, Dongkyu Lim, Feng Qi

In the paper, the authors establish Maclaurin's series expansions and series identities for positive integer powers of the inverse sine function, for positive integer powers of the inverse hyperbolic sine function, for the composite of incomplete gamma functions with the inverse hyperbolic sine function, for positive integer powers of the inverse tangent function, and for positive integer powers of the inverse hyperbolic tangent function, in terms of the first kind Stirling numbers and binomial coefficients, apply the newly established Maclaurin's series expansion for positive integer powers of the inverse sine function to derive a closed-form formula for specific values of partial Bell polynomials and to derive a series representation of the generalized logsine function, and deduce several combinatorial identities involving the first kind Stirling numbers.

Language guided machine action

no code implementations23 Nov 2020 Feng Qi

Here we build a hierarchical modular network called Language guided machine action (LGMA), whose modules process information stream mimicking human cortical network that allows to achieve multiple general tasks such as language guided action, intention decomposition and mental simulation before action execution etc.

Solving Billion-Scale Knapsack Problems

no code implementations2 Feb 2020 Xingwen Zhang, Feng Qi, Zhigang Hua, Shuang Yang

Knapsack problems (KPs) are common in industry, but solving KPs is known to be NP-hard and has been tractable only at a relatively small scale.

Human-like machine thinking: Language guided imagination

no code implementations18 May 2019 Feng Qi, Wenchuan Wu

Human thinking requires the brain to understand the meaning of language expression and to properly organize the thoughts flow using the language.
