Scrambling using different scrambling seeds for defect reduction and improved programming efficiency
Aspects of a storage device including a memory and a controller are provided which allow for efficient programming of cells on word lines using different scrambling seeds. The controller attempts to program cells of the memory by applying data scrambled using a first scrambling seed to the word line. If this attempt to program fails, the controller scrambles the data using a second, different scrambling seed and attempts to program the cells by applying the re-scrambled data to the word line. If this re-attempt also fails, the word line is listed. Then when the controller receives other data, the controller performs a final programming attempt with the other data scrambled using the second scrambling seed. If this further attempt fails, the controller identifies the block including the failed word line as a GBB. Thus, fewer GBBs may be incorrectly identified, reducing DPPM and improving memory yield of the storage device.

The technology disclosed proposes using a combination of computationally cheap, less-accurate bag of words (BoW) model and computationally expensive, more-accurate long short-term memory (LSTM) model to perform natural processing tasks such as sentiment analysis. The use of cheap, less-accurate BoW model is referred to herein as “skimming”. The use of expensive, more-accurate LSTM model is referred to herein as “reading”. The technology disclosed presents a probability-based guider (PBG). PBG combines the use of BoW model and the LSTM model. PBG uses a probability thresholding strategy to determine, based on the results of the BoW model, whether to invoke the LSTM model for reliably classifying a sentence as positive or negative. The technology disclosed also presents a deep neural network-based decision network (DDN) that is trained to learn the relationship between the BoW model and the LSTM model and to invoke only one of the two models.

In various examples, object detections of a machine learning model are leveraged to automatically generate new ground truth data for images captured at different perspectives. The machine learning model may generate a prediction of a detected object at the different perspective, and an object tracking algorithm may be used to track the object through other images in a sequence of images where the machine learning model may not have detected the object. New ground truth data may be generated as a result of the object tracking algorithms outputs, and the new ground truth data may be used to retrain or update the machine learning model, train a different machine learning model, or increase the robustness of a ground truth data set that may be used for training machine learning models from various perspectives.

An image processing method includes: determining a current orientation of a target object; judging whether the current orientation satisfies a set condition; if satisfied, controlling a display screen of the device to display a prompt message to prompt the object to adjust the current orientation to not satisfy the condition; if not satisfied, adjusting a display parameter of a viewing frame to indicate that photographing is allowed; loading the target virtual image to a region where the viewing frame is located, in response to a photographing button being triggered, to acquire a target image after a portion of the object in the viewing frame has been replaced by a target virtual image. A photographer can therefore be guided by the current orientation to photograph correctly, thereby improving photographing quality and experience.

An automated system is provided for classifying materials in remotely-sensed imagery based on automated construction of a dynamic classifier—namely, a classifier that is automatically trained on the same image to which it is then subsequently applied. A first automated process identifies high confidence exemplars of each class using tailored classification techniques. This data is then used to train a supervised classification model (e.g., discriminant analysis), and the resultant classifier is applied to other pixels in the image that are unclassified or uncertain. Dynamic classification is automatically customized to the current image and can yield a more accurate and efficient material classification versus a static (image-independent) or manually trained classifier. It can overcome various confounding factors including inconsistencies in radiometric calibration, atmospheric conditions, and atmospheric distortions of ground spectra; different viewing and illumination geometries; and regional variations in the composition of certain materials like asphalt and concrete.
