ANALYZING OPERATIONAL DATA INFLUENCING CROP YIELD AND RECOMMENDING OPERATIONAL CHANGES
Implementations relate to diagnosis of crop yield predictions and/or crop yields at the field- and pixel-level. In various implementations, a first temporal sequence of high-elevation digital images may be obtained that captures a geographic area over a given time interval through a crop cycle of a first type of crop. Ground truth operational data generated through the given time interval and that influences a final crop yield of the first geographic area after the crop cycle may also be obtained. Based on these data, a ground truth-based crop yield prediction may be generated for the first geographic area at the crop cycle's end. Recommended operational change(s) may be identified based on distinct hypothetical crop yield prediction(s) for the first geographic area. Each distinct hypothetical crop yield prediction may be generated based on hypothetical operational data that includes altered data point(s) of the ground truth operational data.
Apparatus, method, and recording medium
In a related-art technology, training images in accordance with the number of classifications need to be prepared to perform training process. For this reason, in a case where a model is caused to output how much effect of a drug is expressed, a training image needs to be prepared for each expression degree, and it is troublesome to create the model. Provided is an apparatus including an image obtaining unit configured to obtain an evaluation target image depicting a subject of an evaluation target, a probability obtaining unit configured to obtain a recognition probability regarding the evaluation target image by using a model that outputs, in accordance with input of an image, a recognition probability at which a subject of the image is recognized as the subject before effect of a drug is expressed or the subject after the effect of the drug is expressed, and a calculation unit configured to calculate an expression degree of the effect of the drug based on the recognition probability of the evaluation target image.
Noise-robust neural networks and methods thereof
The exemplified methods and systems facilitate the training of a noise-robust deep learning network that is sufficiently robust in the recognition of objects in images having extremely noisy elements such that the noise-robust network can match, or exceed, the performance of human counterparts. The extremely noisy elements may correspond to extremely noisy viewing conditions, e.g., that often manifests themselves in the real-world as poor weather or environment conditions, sub-optimal lighting conditions, sub-optimal image acquisition or capture, etc. The noise-robust deep learning network is trained both (i) with noisy training images with low signal-to-combined-signal-and-noise ratio (SSNR) and (ii) either with noiseless, or generally noiseless, training images or a second set of noisy training images having a SSNR value greater than that of the low-SSNR noisy training images.
