| + ** General steps outlined: |
| + *** Data Request |
| + *** Quality Control and Assurance (if from different sites) |
| + *** Data Integration |
| + *** Quality Control and Assurance (of the integration) |
| + *** Analysis |
| + *** Capture result of analysis … |
| + ** Workflow we developed: |
| + *** (workflow here ...) |
| + ** Useful Actors |
| + *** List Summarizer |
| + **** A set of values in a data column |
| + *** List Comparator |
| + **** Given two sets (lists), do they match? |
| + **** Which ones in the first list aren’t in the second |
| + **** Assign first list values to new values |
| + *** Nested Transpose |
| + **** (site, taxon, count) |
| + **** [(A, x, 3), (A, y, 1), (B, y, 4), (C, z, 2)] |
| + **** Transpose to: |
| + ***** (site, x, y, z) |
| + ***** [(A, 3, 1, 0), (B, 0, 4, 0), (C, 0, 0, 2)] |
| + **** Notes about this from Bertram and Shawn after meeting: |
| + ***** Given an annotated schema S, denoted S*. And a white-box actor q s.t. q(S*) -> S’. We want to “push through” the annotations to obtain S’*. |
| + ***** The “nested” transpose is basically a combination of various lower-level algebraic operators, such as (theoretical) group-by, matrix transpose, projection, etc. So, give q as such a plan of operators, can we reason over the operators (white box-actors) q to obtain S*’? Using symbolic manipulation? Using the chase, e.g., for similar problems in integrity constraints? |
| + ** Often-found pattern of computation |
| + *** Can Kepler/Ptolemy efficiently and conveniently support the following pattern? |
| + *** Given a data set, construct a scatter plot for pairs of variables, allow user to select a subset of the plots -or- pairs of variables of interest, return data subsets based on chosen pairs (with no extraneous variables) |
| + *** Similarly, given data sets, an actor computes a set of regressions, the user is shown the results, the user selects the regressions of interest, and the workflow then proceeds using only those selected regressions |
| + *** These "patterns" can be supported now (with lots of plumbing) using the browser actor. Can we also add functionality to better support/model these patterns? |
