Practical Byzantine-resilient Stochastic Gradient Descent

Sébastien Louis Alexandre Rouault

Algorithms are everywhere. The recipe for the frangipane cake is an algorithm. If all the listed ingredients are available and the cook is sufficiently deft, after a finite number of small, well-defined steps a delicious dessert will exit the oven. Now, wh ...

DASS: Combining Dynamic & Static Scheduling in High-Level Synthesis

Paolo Ienne, Lana Josipovic

A central task in high-level synthesis is scheduling: the allocation of operations to clock cycles. The classic approach to scheduling is static, in which each operation is mapped to a clock cycle at compile-time, but recent years have seen the emergence o ...

Majority Logic Synthesis

Giovanni De Micheli, Mathias Soeken, Eleonora Testa, Luca Gaetano Amarù

The majority function (xyz) evaluates to true, if at least two of its Boolean inputs evaluate to true. The majority function has frequently been studied as a central primitive in logic synthesis applications for many decades. Knuth refers to the majority f ...

Uniting Language Embeddings for Fast and Friendly DSLs

Vojin Jovanovic

The holy grail for a domain-specific language (DSL) is to be friendly and fast. A DSL should be friendly in the sense that it is easy to use by DSL end-users, and easy to develop by DSL authors. DSLs can be developed as entirely new compilers and ecosystem ...
