An intuitive picture or mental image of reality from sense experience is apparently structured from orthogonal and independent sense inputs in association with past memories. Such images are not necessarily visual but may have such qualities. Play of mind with information in mental images processed by molecular actors is guided with rules of reality to assure non-contradictory outcome of actions for successful behaviors (Rogers and Jain 1993). Such functions have evolved to find food before becoming food, and fight or flight when in doubt. Shadows of ignorance that obscure mental images and associated states also have epistemic utility. Their success depends on learning from trials and errors to compensate for incomplete information and uncertainties with consideration of what could go wrong. Outcomes are also influenced by games played on mind by illusions, mistakes, surprises, ignorance. Loss of time, energy, and opportunity associated with ignored or misinterpreted information threaten survival. Equivocation, cynicism, wild goose chase, and vicious circle of sterile ideas encourage contradictory or inconsistent interpretations that compromise outcomes. Throughout the human history, ignorance of horsemen of apocalypse has unleashed havocs, perpetuated wars, epidemics, wrongful medical treatments, and economic disasters. What used to be crisis of ignorance has now become crisis of unintended consequences of inventions and other forms of knowledge. Ignorance of experts and head of states as horsemen of darkness brings misery to countless innocents. In Nay formalism, knowledge (gyan) is what knows with certainty (either as true or false). Identifying uncertainties introduces doubt (syad) in what one knows. For finding ones way around lack of relevant evidence (agyan), wisdom lies in recognition of ignorance and identifies problem to seek solution. Note that these states for propositions are not necessarily related by binary negations.展开更多

The PA of a category indicates to what extent the reference pixels of the category are correctly classified, whereas the UA of a category represents to what extent the other categories are less misclassified into the category in question. Therefore, the UA of the various categories determines the reliability of their interpretation on the classified image and is more important to the analyst than the PA. The present investigation has been performed in order to determine if there occurs improvement in the UA of the various categories on the classified image of the principal components of the original bands and on the classified image of the stacked image of two different years. We performed the analyses using the IRS LISS Ⅲ images of two different years, i.e., 1996 and 2009, that represent the different magnitude of urbanization and the stacked image of these two years pertaining to Ranchi area, Jharkhand, India, with a view to assessing the impacts of urbanization on the UA of the different categories. The results of the investigation demonstrated that there occurs significant improvement in the UA of the impervious categories in the classified image of the stacked image, which is attributable to the aggregation of the spectral information from twice the number of bands from two different years. On the other hand, the classified image of the principal components did not show any improvement in the UA as compared to the original images.展开更多
