Impact of dendritic non-linearities on the computational capabilities of neurons
Multiple neurophysiological experiments have shown that dendritic non-linearities can have a strong influence on synaptic input integration.
Typical and atypical solutions in non-convex neural networks with discrete and continuous weights
We analyze the geometry of the landscape of solutions in both models and find important similarities and differences.
Deep Networks on Toroids: Removing Symmetries Reveals the Structure of Flat Regions in the Landscape Geometry
This lets us derive a meaningful notion of the flatness of minimizers and of the geodesic paths connecting them.
Quantum Approximate Optimization Algorithm applied to the binary perceptron
We apply digitized Quantum Annealing (QA) and Quantum Approximate Optimization Algorithm (QAOA) to a paradigmatic task of supervised learning in artificial neural networks: the optimization of synaptic weights for the binary perceptron.
Native state of natural proteins optimises local entropy
The differing ability of polypeptide conformations to act as the native state of proteins has long been rationalized in terms of differing kinetic accessibility or thermodynamic stability.
Deep learning via message passing algorithms based on belief propagation
Message-passing algorithms based on the Belief Propagation (BP) equations constitute a well-known distributed computational scheme.
Learning through atypical "phase transitions" in overparameterized neural networks
Current deep neural networks are highly overparameterized (up to billions of connection weights) and nonlinear.

Wide flat minima and optimal generalization in classifying high-dimensional Gaussian mixtures
We analyze the connection between minimizers with good generalizing properties and high local entropy regions of a threshold-linear classifier in Gaussian mixtures with the mean squared error loss function.

The properties of flat minima in the empirical risk landscape of neural networks have been debated for some time.
Clustering of solutions in the symmetric binary perceptron
The geometrical features of the (non-convex) loss landscape of neural network models are crucial in ensuring successful optimization and, most importantly, the capability to generalize well.
Natural representation of composite data with replicated autoencoders
Generative processes in biology and other fields often produce data that can be regarded as resulting from a composition of basic features.

Rectified Linear Units (ReLU) have become the main model for the neural units in current deep learning systems.
Shaping the learning landscape in neural networks around wide flat minima
In the case of SGD and cross-entropy loss, we show that a slow reduction of the norm of the weights along the learning process also leads to WFM.
On the role of synaptic stochasticity in training low-precision neural networks
Stochasticity and limited precision of synaptic weights in neural network models are key aspects of both biological and hardware modeling of learning processes.
Parle: parallelizing stochastic gradient descent
We propose a new algorithm called Parle for parallel training of deep networks that converges 2-4x faster than a data-parallel implementation of SGD, while achieving significantly improved error rates that are nearly state-of-the-art on several benchmarks including CIFAR-10 and CIFAR-100, without introducing any additional hyper-parameters.
Efficiency of quantum versus classical annealing in non-convex learning problems
Their energy landscapes is dominated by local minima that cause exponential slow down of classical thermal annealers while simulated quantum annealing converges efficiently to rare dense regions of optimal solutions.

This paper proposes a new optimization algorithm called Entropy-SGD for training deep neural networks that is motivated by the local geometry of the energy landscape.
Unreasonable Effectiveness of Learning Neural Networks: From Accessible States and Robust Ensembles to Basic Algorithmic Schemes
We define a novel measure, which we call the "robust ensemble" (RE), which suppresses trapping by isolated configurations and amplifies the role of these dense regions.

Learning in neural networks poses peculiar challenges when using discretized rather then continuous synaptic states.

We introduce a novel Entropy-driven Monte Carlo (EdMC) strategy to efficiently sample solutions of random Constraint Satisfaction Problems (CSPs).

We also show that the dense regions are surprisingly accessible by simple learning protocols, and that these synaptic configurations are robust to perturbations and generalize better than typical solutions.
