Winner-Take-All Autoencoders
In this paper, we propose a winner-take-all method for learning hierarchical sparse representations in an unsupervised fashion. We first introduce fully-connected winner-take-all autoencoders which use mini-batch statistics to directly enforce a lifetime sparsity in the activations of the hidden units. We then propose the convolutional winner-take-all autoencoder which combines the benefits of ...
متن کاملWinner-take-all price competition
This paper examines the competitiveness of winner-take-all price competition in homogeneous product oligopoly environments where underlying buyer demands and/or firms’ costs need not be continuous. Our analysis is motivated by the observation that a variety of economic settings have these features. For example, in 1996 an Ivy League university solicited bids from several vendors for its initiat...
متن کاملWinner-Take-All EM Clustering
The EM algorithm is often used with mixture models to cluster data, but for efficiency reasons it is sometimes desirable to produce hard clusters. Several hard clustering limits of EM are known. For example, k-means clustering can be derived from EM in a Gaussian mixture model by taking the limit of all variances going to zero. We present a new method of deriving Winner-Take-All versions of EM ...
متن کاملDynamically-Adaptive Winner-Take-All Networks
Winner-Take-All (WTA) networks. in which inhibitory interconnections are used to determine the most highly-activated of a pool of unilS. are an important part of many neural network models. Unfortunately, convergence of normal WT A networks is extremely sensitive to the magnitudes of their weights, which must be hand-tuned and which generally only provide the right amount of inhibition across a...
متن کاملThe Temporal Winner-Take-All Readout
How can the central nervous system make accurate decisions about external stimuli at short times on the basis of the noisy responses of nerve cell populations? It has been suggested that spike time latency is the source of fast decisions. Here, we propose a simple and fast readout mechanism, the temporal Winner-Take-All (tWTA), and undertake a study of its accuracy. The tWTA is studied in the f...
