One of these transformations is related to the Zaks' sequence (S.~Zaks, \\\\emph{Theor. Comput. Sci.} extbf{10} (1980)) for encoding binary trees, and we thus provide the first succinct binary tree representatio

A spatial region, such as a geographic region, may be represented by a series of vectors in a binary tree or other binary representation. The binary tree may be generated by successively dividing a region into smaller rectangles or vectors, until either a vector is completely within the region...
在我们的工作中,我们使用一个霍夫曼树(binary Huffman tree),因为它将短codes分配给高频词,从而加快了训练速度。之前已经观察到,根据出现频率组合单词可以很好的作为基于神经网络的语言模型的一种简单加速技术。2.2 负采样Negative Sampling分层softmax的替代方案是噪声对比估计(NCE),由Gutmann和Hyvarinen引入,并由Mnih和...

In particular, the SDRs in the model I’ll be describing,Sparsey(1996,2010,2014,2017), are smallsetsof binary units chosen from a much larger “coding field“, where these SDRs (sets) can intersect to arbitrary degrees. This raises the possibility of using the size of intersection of two...
Conventional Vector Autoregressive (VAR) modelling methods applied to high dimensional neural time series data result in noisy solutions that are dense or have a large number of spurious coefficients. This reduces the speed and accuracy of auxiliary comp
resulting to a vector of the selected graph-based features, which are then used in our analysis as described in section "Graph-based features". It should be noticed that, the adjacency matrix can have a binary or a weighted form. However, in our proposed methodology the binary version gave...
使用σ(⋅) 函数做二分类,因为是binary tree。这也解释了上述真值函数为什么输出-1,因为 σ(x) 和1−σ(x)=σ(−x) 。所以在当前节点上,如果为1则向左/右走,如果为-1则向右/左走,所以乘积上限为 L(w)−1 而不是 L(w) ,如图 Hierarchical Softmax 虽然我们依然有 2W−1 个节点和特征,但...
