Discovering sparse interpretable dynamics from partial observations

چکیده

Identifying the governing equations of a nonlinear dynamical system is key to both understanding physical features and constructing an accurate model dynamics that generalizes well beyond available data. We propose machine learning framework for discovering these using only partial observations, combining encoder state reconstruction with sparse symbolic model. Our tests show this method can successfully reconstruct full identify underlying variety ODE PDE systems.

Discovering interpretable classification rules from neural processed data

In this paper we describe a neuro-fuzzy model to extract interpretable classification rules from examples. Such model is trained in a parameter subspace where a number of formal properties, which characterize understandable knowledge bases, are satisfied. To deal with the curse of dimensionality problem, which occurs when our model is used in high-dimensional classification tasks, an "A Priori ...

SPINE: SParse Interpretable Neural Embeddings

Prediction without justification has limited utility. Much of the success of neural models can be attributed to their ability to learn rich, dense and expressive representations. While these representations capture the underlying complexity and latent trends in the data, they are far from being interpretable. We propose a novel variant of denoising k-sparse autoencoders that generates highly ef...

Sparse dynamics for partial differential equations.

We investigate the approximate dynamics of several differential equations when the solutions are restricted to a sparse subset of a given basis. The restriction is enforced at every time step by simply applying soft thresholding to the coefficients of the basis approximation. By reducing or compressing the information needed to represent the solution at every step, only the essential dynamics a...

Discovering Personal Paths from Sparse GPS Traces

Personal paths capture “personal meaningful places” [13, 14] in temporal sequence. Knowledge of a user’s paths enables novel and useful features for location-aware applications, e.g., traffic condition updates for commuting routes, carpool partner finding with similar commuting routes and schedules. Prior work has explored algorithms to discover “significant locations” [1,2] and “transportation...

Learning from Partial Observations

We present a general machine learning framework for modelling the phenomenon of missing information in data. We propose a masking process model to capture the stochastic nature of information loss. Learning in this context is employed as a means to recover as much of the missing information as is recoverable. We extend the Probably Approximately Correct semantics to the case of learning from pa...
