Abstract: The present disclosure relates to machine-learning generalization, and in particular to techniques for regularizing machine-learning The present disclosure relates to machine-learning generalization, and in particular to techniques for regularizing machine-learning models using biological systems (e.g. brain data) to engineer machine-learning-algorithms that can generalize better. Particularly, aspects are directed to a computer implemented method that includes measuring a plurality of biological responses (e.g. neural responses to stimuli or other variables such body movements); generating data (e.g. responses to stimuli) using the predictive model which can denoise biological data and extract task relevant information; scaling and transforming these predictions (e.g. measure representational similarities between stimuli); and using the biologically derived data to regularize machine-learning-algorithms.

Abstract: Expanded performance opportunities for imaging spectrometers are described using ?-polynomial freeform surfaces in reflective and diffractive optics. The imaging spectrometers are generally of a type that include an entrance aperture for admitting radiation over a range of wavelengths, a detector array, a primary reflective optic with optical power, a secondary reflective diffractive optic, and a tertiary reflective optic with optical power for collectively imaging the entrance aperture onto the detector array through a range of dispersed positions. One or more of the primary reflective optic, the secondary reflective diffractive optic, and the tertiary reflective optic can include a ?-polynomial optical surface with no axis of symmetry and represented by a function that depends on both a radial component and an azimuthal component.

Abstract: An apparatus comprises a light source which produces a first radiation within a first wavelength range and which produces a second radiation within a second wavelength range when a property of the light source is changed. The apparatus further comprises an optical device which receives the first radiation and attenuates the first radiation to emit a first attenuated radiation having a first perceived brightness. The optical device also receives the second radiation and attenuates the second radiation to emit a second attenuated radiation having a second perceived brightness. The first and second perceived brightnesses are approximately equal.

Abstract: Provided are assemblies and processes for achieving desirable homogenization and mixing of one or more light sources. The assemblies include the use of diffusers and light pipes in a particular configuration that allows very good homogenization performance while reducing the requisite length of light pipe. In particular, a length of a light-pipe homogenizer can be substantially reduced by diffusing the light after it has been partially pre-mixed by a light pipe. Additional mixing can take place after diffusion. For example, a diffuser can be positioned within a light pipe or sandwiched between two light pipes. In some embodiments, the diffuser is placed at a point along a light pipe where the light from each source or each portion of a single source substantially covers the diffuser approximately equally. Consequently, a rate of homogenization can be increased, thereby reducing the required length of the complete homogenization system.
