Abstract: Techniques for refinement of data pipelines are provided. An original file of serialized objects is received, and an original pipeline comprising a plurality of transformations is identified based on the original file. A first computing cost is determined for a first transformation of the plurality of transformations. The first transformation is modified using a predefined optimization, and a second cost of the modified first transformation is determined. Upon determining that the second cost is lower than the first cost, the first transformation is replaced, in the original pipeline, with the optimized first transformation.

Abstract: Application of multi-task learning technique(s) to machine logic (for example, software) used to detect financial transactions that are fraudulent or at least considered likely to be fraudulent. Some embodiments include adjustments and/or additions to conventional multi-task learning techniques in order to make the multi-task learning techniques more suitable for use in fraud detection software. One example of this is compensation for class imbalances that are to be expected as between the likely-fraud and not-likely-fraud classes of data sets (for example, training data sets, runtime data sets).

Abstract: The performance of a computer performing electronic design analysis is improved by representing a putative circuit design as a set of movable blocks of predetermined size which must fit into a bounding box (said blocks include a plurality of subsets to be interconnected by wires) and initially placing the set of blocks by quadratic initialization. Each of the blocks has first and second coordinates and weights are assigned to nets connecting those of the blocks within the subsets, the quadratic initialization in turn includes determining a cost of each of the nets connecting any two of the blocks within the subsets as one-half of a sum of squares of distances between the any two of the blocks; and minimizing a total cost over all of the nets to determine an initial placement of the set of blocks. Analytical placement is then carried out based on the initial quadratic placement.

Abstract: A physical synthesis system includes a path straightening module, an ideal critical point identification (ID) module, and a free-space ID module. The path straightening module identifies at least one meandering critical path of a circuit, and generates a reference curve based on dimensions of the critical path. The ideal critical point ID module identifies at least one critical point on the reference curve. The free-space ID module identifies at least one free-space to receive a gate with respect to at least one critical point. The physical synthesis system further includes a free-space selector module and a gate modification module. The free-space selector module determines a modified slack timing value based on relocating the gate to the at least one free-space. The gate modification module moves the gate to the at least one free-space when the modified slack timing value is greater than an initial slack timing value.
