jingyimei opened a new pull request #412: DL: Standardize the data types used for keras and sql URL: https://github.com/apache/madlib/pull/412 JIRA: MADLIB-1358 Under deep_learning module (this includes preprocessor, keras model arch table, fit, evaluate and predict), we made the following changes: 1. independent_var and normalizing const to be float32 (REAL). 2. dependent_var to be a 16-bit integer (SMALLINT) We were previously converting independent_var to float64 which is not necessary at all. Instead we might be able to save resources by just using float32 for the independent_var and int16 for the one hot encoded dependent_var. Co-authored-by: Nikhil Kak <[email protected]>
