Deductive Verification of Chain-of-Thought Reasoning

1 code implementation6 Jun 2023 Zhan Ling, Yunhao Fang, Xuanlin Li, Zhiao Huang, Mingu Lee, Roland Memisevic, Hao Su

In light of this, we propose to decompose a reasoning verification process into a series of step-by-step subprocesses, each only receiving their necessary context and premises.

Is end-to-end learning enough for fitness activity recognition?

no code implementations14 May 2023 Antoine Mercier, Guillaume Berger, Sunny Panchal, Florian Letsch, Cornelius Boehm, Nahua Kang, Ingo Bax, Roland Memisevic

End-to-end learning has taken hold of many computer vision tasks, in particular, related to still images, with task-specific optimization yielding very strong performance.

Metaphors We Learn By

no code implementations11 Nov 2022 Roland Memisevic

In this essay we relate parameter sharing (``weight sharing'') to analogy making and the school of thought of cognitive metaphor.

On the effectiveness of task granularity for transfer learning

1 code implementation24 Apr 2018 Farzaneh Mahdisoltani, Guillaume Berger, Waseem Gharbieh, David Fleet, Roland Memisevic

We describe a DNN for video classification and captioning, trained end-to-end, with shared features, to solve tasks at different levels of granularity, exploring the link between granularity in a source task and the quality of learned features for transfer learning.

Webb, Matthew Willson, Kelvin Xu, Lijun Xue, Li Yao, Saizheng Zhang, Ying Zhang

Since its introduction, it has been one of the most used CPU and GPU mathematical compilers - especially in the machine learning community - and has shown steady performance improvements.

Generating images with recurrent adversarial networks

1 code implementation16 Feb 2016 Daniel Jiwoong Im, Chris Dongjoo Kim, Hui Jiang, Roland Memisevic

Gatys et al. (2015) showed that optimizing pixels to match features in a convolutional network with respect reference image features is a way to render images of high visual quality.

Regularizing RNNs by Stabilizing Activations

1 code implementation26 Nov 2015 David Krueger, Roland Memisevic

We stabilize the activations of Recurrent Neural Networks (RNNs) by penalizing the squared distance between successive hidden states' norms.

Denoising Criterion for Variational Auto-Encoding Framework

no code implementations19 Nov 2015 Daniel Jiwoong Im, Sungjin Ahn, Roland Memisevic, Yoshua Bengio

Denoising autoencoders (DAE) are trained to reconstruct their clean inputs with noise injected at the input level, while variational autoencoders (VAE) are trained with noise injected in their stochastic hidden layer, with a regularizer that encourages this noise injection.


RATM: Recurrent Attentive Tracking Model

no code implementations29 Oct 2015 Samira Ebrahimi Kahou, Vincent Michalski, Roland Memisevic

The proposed Recurrent Attentive Tracking Model performs well on all three tasks and can generalize to related but previously unseen sequences from a challenging tracking data set.

Dropout as data augmentation

no code implementations29 Jun 2015 Xavier Bouthillier, Kishore Konda, Pascal Vincent, Roland Memisevic

Dropout is typically interpreted as bagging a large number of models sharing parameters.

Conservativeness of untied auto-encoders

no code implementations25 Jun 2015 Daniel Jiwoong Im, Mohamed Ishmael Diwan Belghazi, Roland Memisevic

We discuss necessary and sufficient conditions for an auto-encoder to define a conservative vector field, in which case it is associated with an energy function akin to the unnormalized log-probability of the data.


On Using Very Large Target Vocabulary for Neural Machine Translation

1 code implementation IJCNLP 2015 Sébastien Jean, Kyunghyun Cho, Roland Memisevic, Yoshua Bengio

The models trained by the proposed approach are empirically found to outperform the baseline models with a small vocabulary as well as the LSTM-based neural machine translation models.

Zero-bias autoencoders and the benefits of co-adapting features

no code implementations13 Feb 2014 Kishore Konda, Roland Memisevic, David Krueger

We show that negative biases are a natural result of using a hidden layer whose responsibility is to both represent the input data and act as a selection mechanism that ensures sparsity of the representation.

Modeling sequential data using higher-order relational features and predictive training

no code implementations10 Feb 2014 Vincent Michalski, Roland Memisevic, Kishore Konda

In this work we extend bi-linear models by introducing "higher-order mapping units" that allow us to encode transformations between frames and transformations between transformations.

Unsupervised learning of depth and motion

We present a model for the joint estimation of disparity and motion.

Learning to encode motion using spatio-temporal synchrony

no code implementations13 Jun 2013 Kishore Reddy Konda, Roland Memisevic, Vincent Michalski

To this end, we show that the detection of spatial transformations can be viewed as the detection of synchrony between the image sequence and a sequence of features undergoing the motion we wish to detect.

We describe a log-bilinear" model that computes class probabilities by combining an input vector multiplicatively with a vector of binary latent variables.
