Help us to further improve by taking part in this short 5 minute survey Variational inference with a factorized Gaussian posterior estimate is a widely-used approach for learning parameters and hidden variables. First, we present a supervised generative model to constrain the intermediate process of the RL policy, which is used to generate a future observation from a current observation and a target.

Later feeding another image as input of a such trained DNN shall give as output the decision if there are one or more of the object classes present in the image. Empirically, a regularizing effect can be observed that is poorly understood.

An Information-Theoretic View for Deep Learning Jingwei Zhang∗ Tongliang Liu∗ Dacheng Tao∗ Abstract Deep learning has transformed computer vision, natural language processing, and speech recognition[2, 5, 14, 8].

123 0 obj At the same time, deep learning, as a glorified signal processing tool, lacks a solid information-theoretical basis and strong connections with the fundamental information-theoretic results in channel and source coding, hypothesis testing, estimation, and security. In this work, we show how mean field inference improves generalization by limiting mutual stream

The inference from a hidden layer to the output layer is then interpreted as a variational approximation to the layer’s decoding of relevant information in the MIB.

The Information Bottleneck (IB) method provides an insightful and principled approach for balancing compression and prediction for representation learning. Application-specific experimental analyses of information–theoretic cost functions are welcome, given that the proposed cost functions are justified from first principles and rigorously developed.

(2005) employ information-theoretic metrics for sensor selection and sensor placement in sensor networks. However, two critical questions remain obscure: (1) why do deep neural networks generalize better than shallow networks; and (2) Subscribe to receive issue release notifications and newsletters from MDPI journals Therefore, the computation of the mutual information for DNNs and its visualization on the information plane mostly focused on low-complexity fully connected networks. Information theory concepts are leveraged with the goal of better understanding and improving Deep Neural Networks (DNNs). We wish to mention that the concurrent Special Issue “Information–Theoretic Approaches in Deep Learning” has a potential overlap with ours. All these individual networks can have different architectures and different initial weights while being trained with the same data set (input and output).Generally, after many learning epochs, information about the input within all layers is gradually decreasing.

Information theory concepts are leveraged with the goal of better understanding and improving Deep Neural Networks (DNNs). arXiv preprint arXiv:1804.09060. The information plane of neural networks describes the behavior during training of the mutual information at various depths between input/output and hidden-layer variables.

With MIB, we take the novel perspective that each layer of an SNN is a bottleneck whose learning goal is to encode relevant information in a compressed form from the data. Experimental results show that the regularization stabilizes the test accuracy and significantly reduces its variance. The statements, opinions and data contained in the journals are solely An Information-Theoretic View for Deep Learning.

Each tree is made of nodes trained independently of The Information Bottleneck (IB) method provides an insightful and principled approach for balancing compression and prediction for representation learning. Empirically, a regularizing effect can be observed that is poorly understood.

The IB theory delivers a description picture with two parameters (the two axes of the information plane) instead of the millions to billions of connection parameters of a DNN.In a next part more details of the theory will be provided. Original article was published on Deep Learning on Medium. We describe a classifier made of an ensemble of decision trees, designed using information theory concepts.

Information bottleneck (IB) is a technique for extracting information in one random variable

In this work, we further extend IB to multiple Markov bottlenecks (i.e., latent variables that form a Markov chain), namely Markov information bottleneck (MIB), which particularly fits better in the context of stochastic neural networks (SNNs) than the original IB.
