Coordinate data is encoded as a distributed representation for processing and analysis by a machine-intelligence system such as a hierarchical temporal memory system. Input coordinates represented in coordinate space having at least one dimension are obtained. The input coordinates change over time. A corresponding region around each of the input coordinates in the coordinate space is determined. A subset of coordinates within the corresponding region for each of the input coordinates is selected. A distributed representation for each of the input coordinates reflecting the selected subset of coordinates for each of the input coordinates is generated. The distributed representation may be provided to one or more processing nodes for detection of temporal sequences and spatial patterns. Based on discrepancies between predicted coordinate data and actual coordinate data, anomalies may be detected.

In a chromatic point sensor, distance measurements are based on a distance-indicating subset of intensity profile data, which is selected in a manner that varies with a determined peak position index coordinate (PPIC) of the profile data. The PPIC indexes the position a profile data peak. For profile data having a particular PPIC, the distance-indicating subset of the profile data is selected based on particular index-specific data-limiting parameters that are indexed with that same particular PPIC. In various embodiments, each set of index-specific data-limiting parameters indexed with a particular PPIC characterizes a distance-indicating subset of data that was used during distance calibration operations corresponding to profile data having that PPIC. Distance-indicating subsets of data may be compensated to be similar to a corresponding distance-indicating subset of data that was used during calibration operations, regardless of overall intensity variations and detector bias signal level variations.

Representations of data inversions are generated by alternate forms of maximum likelihood estimating and associated least-squares and regression analysis which are rendered in correspondence with either single component residual deviations or projections between data samples and inversion-conforming data sets. Deficiencies in representing likelihood as related to errors-in-variables data and heterogeneous precision are compensated by composite weighting of likelihood elements. Composite weight factors employ both normalization to establish non-skewed homogeneous likelihood elements and fundamental weighting to compensate for associated non-linearly and establish common units for combining orthogonal coordinate-oriented data-point projections. Respective weight factors are related to alternately considered fundamental variables. Variance or alternate representation, as related to statistically independent sampling, is utilized as assumed applicable or replaced by composite variability representing single coordinate variations as affected by orthogonal coordinate sampling dispersions. Statistical rendition is generated as a replacement for unquantifiable dependent variable representation.
