On Disentangled Analysis-by-Synthesis Shape Representations
… vision (CV). In particular, we explore the Analysis-by-Synthesis (AbS) paradigm, which postulates perceptual inference as the inversion of a generative process. This provides several advantages: weak supervision, via the reconstructive signal, and the opportunity for disentanglement, via …

Characterising Performative Speech Modes via Analysis by Synthesis
Due to technological advances in recent years, there has been increased interest in both Linguistics and Artificial Intelligence research in performative speech, and its acoustic and perceptual properties. However, this speech domain is abstract and highly nuanced, making it highly difficult to …

Verbal short-term storage and analysis-by-synthesis of speech : evidence for common mechanisms
… been directed toward elucidating the process(es) by which humans retain verbal material for short intervals of time. The purpose of the present paper will be to explore the extent to which such memorial processes can be identified with processes which may be employed in information processing …

Gaze Estimation with Graphics
… these problems in two different ways: learning-by-synthesis and analysis-by-synthesis. Learning-by-synthesis is the process of training a machine learning system with synthetic data, i.e. data that has been rendered with graphics rather than collected by hand. Analysis-by-synthesis is a computer …

Understanding Human Perception Through MooneyFaces
… robust? We consider a version of the analysis-by-synthesis proposal for perception, in which visual input is interpreted by inverting a model of image formation, as a potential model for human visual perception. Taking Mooney faces as a case study, we evaluate the model against human …

Inferring Shape and Material from Sound
… Another approach is to tackle the problem in an analysis-by-synthesis framework, where we iterative update current estimates given a generative model. This, however, requires sophisticated generative models, which is too computationally expensive to support iterative inference. Finally, despite …

Visual tracking of highly articulated objects using massively parallel processors
… appearances. In this work, we consider an analysis by synthesis approach to this difficult tracking problem. We attempt to overcome the vast amount of computation required by implementing the algorithm on commodity GPUs. We also collect a lengthy sequence of hand motions from five cameras …

Gestural overlap of stop-consonant sequences
This study used an analysis-by-synthesis approach to discover possible principles governing the coordination of oral and laryngeal articulators in the production of English stop-consonant sequences. Recorded utterances containing stop-consonant sequences were analyzed acoustically, with focus on …

Lensing Machines : representing perspective in machine learning
… values for variables in the model, allowing analysis by synthesis or model criticism, towards an iterative cycle of model specification, estimation, and critique. However, many datasets represent a combination of several viewpoints - different ways of looking at the same data that leads to …

An analog VLSI vocal tract
… experimental integrated-circuit vocal tract by mapping fluid volume velocity to current, fluid pressure to voltage, and linear and nonlinear mechanical impedances to linear and nonlinear electrical impedances. The 275 jW analog vocal tract chip can be used with auditory processors in a …

Understanding computation through low-dimensional dynamics with recurrent neural networks
… network (RNN) model. To begin, I propose an analysis-by-synthesis method that uses local constraints on population activity to create RNNs that can solve a task. I demonstrate this method by creating networks that implement variations of a ring attractor, a classic model of representation in …
