Summary:To provide an analyzer which can improve accuracy in specifying a part of an image that causes incorrect inference, an analysis program, and an analysis method.SOLUTION: An analyzer includes: an image generation unit which generates a refine image by maximizing a score of a correct label of inference from an incorrect inference image in which an incorrect label is inferred in image recognition processing; an attention-degree map generation unit which generates an attention-degree map indicating an area of pixels in the refine image focused in inference and having the same level in degrees of attention; and a visualization unit which visualizes a part of image that causes incorrect inference by clipping an image corresponding to an area of a predetermined level in the attention-degree map out of images calculated based on the incorrect inference image and the refine image and adjusting intensity by pixel.SELECTED DRAWING: Figure 1 【課題】誤推論の原因となる画像箇所を特定する際の精度を向上させることができる解析装置、解析プログラム及び解析方法を提供する。【解決手段】解析装置は、画像認識処理の際に誤ったラベルが推論される誤推論画像から、推論の正解ラベルのスコアを最大化させたリファイン画像を生成する画像生成部と、リファイン画像の複数の画素のうち推論時に注目した注目度合いが同レベルとなる画素の領域を示す注目度合いマップを生成する注目度合いマップ生成部と、誤推論画像と前記リファイン画像とに基づいて演算される画像のうち、注目度合いマップの所定レベルの領域に対応する画像を切り出して画素単位で強度調整処理することで、誤推論の原因となる画像箇所を可視化する可視化部と、を有する。【選択図】図１
