MIT study examines neural networks that build their own learning machinery

MIT researchers demonstrated an artificial neural network that can build its own learning machinery using simple connection-change rules. It learned pattern recognition and image classification, with performance reported as comparable to designed networks.

MIT News reported on October 13 on a study published in PNAS on October 9. The McGovern Institute and K. Lisa Yang ICoN Center model starts with randomly connected units and lets them form functional network structures under shared local rules.

The researchers say self-assembling motifs act as building blocks for functional circuits and the network develops through optimization similar to gradient descent. The work does not show that it learns exactly like a biological brain; the authors describe it as a starting point for biologically informative models.

Simulation examines how tin solder boundaries absorb dislocations

Researchers at Los Alamos National Laboratory and Iowa State University modelled how a (301) twin boundary in β-tin interacts with dislocations. The simulation concerns deformation mechanisms in tin alloys used in electronic solder.

New epitaxy method stabilised four metastable crystalline phases

A research team led by MIT used a method it calls diffusion-activated epitaxy to experimentally stabilise four distinct crystalline phases. The preprint says diffraction and microscopy data for three phases did not match structures in the crystal databases examined.
