Exploring the role of conceptual scaffolding in solving synthesis problems

open access: yesPhysical Review Special Topics. Physics Education Research, 2011
It is well documented that when solving problems experts first search for underlying concepts while students tend to look for equations and previously worked examples.

What works with worked examples: Extending self-explanation and analogical comparison to synthesis problems

open access: yesPhysical Review Physics Education Research, 2017
The ability to solve physics problems that require multiple concepts from across the physics curriculum—“synthesis” problems—is often a goal of physics instruction.

Exact and approximate methods for proving unrealizability of syntax-guided synthesis problems [PDF]

open access: yesACM-SIGPLAN Symposium on Programming Language Design and Implementation, 2020
We consider the problem of automatically establishing that a given syntax-guided-synthesis (SyGuS) problem is unrealizable (i.e., has no solution). We formulate the problem of proving that a SyGuS problem is unrealizable over a finite set of examples as ...

StackGAN: Text to Photo-Realistic Image Synthesis with Stacked Generative Adversarial Networks [PDF]

open access: yesIEEE International Conference on Computer Vision, 2016
Synthesizing high-quality images from text descriptions is a challenging problem in computer vision and has many practical applications. Samples generated by existing textto- image approaches can roughly reflect the meaning of the given descriptions, but
