Dec 26, 2016 · 2. Sparse, as can be deduced from the meaning in layman English refers to sparsity in the connections between neurons, basically, the weights have non-significant values (close to 0) In some cases it might also refer to cases where we do not have all connections and very less connections itself (less weights) answered Sep 29, 2022 at 18:40.
Dec 26, 2019 · Create a sparse index on the age of the customers collection by adding {sparse: true} db.customers.createIndex( { age: 1 }, { sparse: true } ); This query will use the sparse index because the criteria in the query goes well with the sparse index. We only want to return customers whose age is greater than 21, if the customer doens’t have age ...
Nov 29, 2017 · Using sparse-checkout with an existing repository.

Mar 11, 2021 · If the output of the different transformers contains sparse matrices, these will be stacked as a sparse matrix if the overall density is lower than this value. Use sparse_threshold=0 to always return dense. When the transformed output consists of all dense data, the stacked result will be dense, and this keyword will be ignored.
Jul 6, 2011 · 27. In a regular database, rows are sparse but columns are not. When a row is created, storage is allocated for every column, irrespective of whether a value exists for that field (a field being storage allocated for the intersection of a row and and a column). This allows fixed length rows greatly improving read and write times.
Aug 23, 2018 · 1. If the number of the edges is close to the maximum number of edges in a graph, then that graph is a Dense graph. In a dense graph, every pair of vertices is connected by one edge. The Sparse graph is completely the opposite. If a graph has only a few edges (the number of edges is close to the minimum number of edges), then it is a sparse graph.
Apr 15, 2017 · vectorized_words = parse.csr_matrix(vectorize_words(nostopwords,glove_dict)) #calculating the distance/similarity between each vector in the matrix cos_similiarity = cosine_similarity(vectorized_words, dense_output=False) # since there are duplicates like (5,0) and (0,5) which we should remove, I use scipy's triu function coo_cossim = cos_similiarity.tocoo() vector_similarities = sparse.triu(coo_cossim, k = 1).tocsr()
Oct 26, 2019 · For sparse_categorical_crossentropy, For class 1 and class 2 targets, in a 5-class classification problem, the list should be [1,2]. Basically, the targets should be in integer form in order to call sparse_categorical_crossentropy. This is called sparse since the target representation requires much less space than one-hot encoding.
