Although effective uncertainty estimation can be a key consideration in the development of safe and fair artificial intelligence systems, most of today’s large-scale deep learning applications are lacking in this regard.

To accelerate research in this field, a team from DeepMind has proposed epistemic neural networks (ENNs) as an interface for uncertainty modelling in deep learning, and the KL divergence from a target distribution as a precise metric to evaluate ENNs. In the paper Epistemic Neural Networks, the team also introduces a computational testbed based on inference in a neural network Gaussian process, and validates that the proposed ENNs can improve performance in terms of statistical quality and computational cost.

The researchers say all existing approaches to uncertainty modelling in deep learning can be expressed as ENNs, presenting a new perspective on the potential of neural networks as computational tools for approximate posterior inference.

A first-of-its-kind 3D-printed concrete bridge has been unveiled in Venice, Italy. The bridge is a demonstration of a new 3D printing method resulting in a structure requiring no mortar or steel reinforcement.

The bridge was developed as part of a collaboration between ETH Zurich and Zaha Hadid Architects’ Computation and Design Group. The unreinforced structure was created by 3D-printing concrete blocks using a novel type of concrete ink produced by a company called Holcim.

“This precise method of 3D concrete printing allows us to combine the principles of traditional vaulted construction with digital concrete fabrication to use material only where it is structurally necessary without producing waste,” explains Philippe Block, a researcher from ETH Zurich.

Elon Musk recently hinted at a very welcome and simple update for Tesla’s vehicles, especially those which have already replaced their 12-volt batteries in the past. According to the CEO, Tesla would be looking into the idea of equipping older vehicles with a 12-volt lithium-ion battery, similar to the Model S Plaid.

Musk’s update came as a response to Tesla owner Rich Teer, who inquired if it was possible to have the company’s older vehicles be equipped with the company’s newer 12-volt lithium-ion battery. This was a good point considering that the conventional 12-volt lead-acid battery used in vehicles like the Model 3 and Model Y tend to get discharged, in some cases, multiple times per year.

In his response, Musk stated that Tesla would try to roll out such an initiative, especially as it would be beneficial for the company’s cars. A 12-volt lithium-ion battery would last far longer than a conventional lead-acid battery, after all, and according to Musk, Tesla’s goal is to reduce service in its vehicles anyway. “Unlike other makers of cars, our goal is *not* to profit from service. Best service is not needing service in the first place,” Musk noted.
