Associative memory has been a prominent candidate for the computation performed by the massively recurrent neocortical networks. Attractor networks implementing associative memory have offered mechanistic explanation for many cognitive phenomena. However, attractor memory models are typically trained using orthogonal or random patterns to avoid interference between memories, which makes them unfeasible for naturally occurring complex correlated stimuli like images. We approach this problem by combining a recurrent attractor network with a feedforward network that learns distributed representations using an unsupervised Hebbian-Bayesian learning rule. the resulting network model incorporates many known biological properties: unsupervised learning, Hebbian plasticity, sparse distributed activations, sparse connectivity, columnar and laminar cortical architecture, etc. We evaluate the synergistic effects of the feedforward and recurrent network components in complex patternrecognition tasks on the MNIST handwritten digits dataset. We demonstrate that the recurrent attractor component implements associative memory when trained on the feedforward-driven internal (hidden) representations. the associative memory is also shown to perform prototype extraction from the training data and make the representations robust to severely distorted input. We argue that several aspects of the proposed integration of feedforward and recurrent computations are particularly attractive from a machinelearning perspective.

Modern image recognition systems require a large amount of training data. In contrast, humans can learn the concept of new classes from only one or a few image examples. A machinelearning problem with only a few training samples is called few-shot learning and is a key challenge in the image recognition field. In this paper, we address one-shot learning, which is a type of few-shot learning in which there is one training sample per class. We propose a one-shot learning method based on metric learningthat is characterized by data augmentation of a test target along withthe training samples. Experimental results demonstrate that expanding both training samples and test target is effective in terms of improving accuracy. On a benchmark dataset, the accuracy improvement by the proposed method is 2.55% points, while the improvement by usual data augmentation which expands the training samples is 1.31% points. Although the proposed method is very simple, it achieves accuracy that is comparable or superior to some of existing methods.

We focus on the problem of producing well-calibrated out-of-distribution (OOD) detectors, in order to enable safe deployment of medical image classifiers. Motivated by the difficulty of curating suitable calibration datasets, synthetic augmentations have become highly prevalent for inlier/outlier specification. While there have been rapid advances in data augmentation techniques, this paper makes a striking finding that the space in which the inliers and outliers are synthesized, in addition to the type of augmentation, plays a critical role in calibrating OOD detectors. Using the popular energy-based OOD detection framework, we find that the optimal protocol is to synthesize latent-space inliers along with diverse pixel-space outliers. Based on empirical studies with multiple medical imaging benchmarks, we demonstrate that our approach consistently leads to superior OOD detection (15% - 35% in AUROC) over the state-of-the-art in a variety of open-set recognition settings.

this paper highlights the importance of deep learning-based litchi segmentation in precision agriculture using machine vision. the proposed method involves preparing a mixed UAV litchi and MinneApple database, consisting of 2000 images of the same size 256 x 256. this paper introduces a modified Mask-RCNN-based instance segmentation model;incorporating a spatial attention block in the backbone network ResNet101, to mitigate one of the significant challenges in litchi counting, i.e., occlusion. the results demonstrate that the proposed model achieves a mean Average Precision (mAP), recall, and F1-score of 90.81%, 89.00%, and 90.35%, respectively, for separated and unoccluded litchis, and an mAP, recall, and F1-score of 81.41%, 82.42%, and 81.91%, respectively, for occluded litchis. the proposed model provides better detection accuracy while minimizing computational burden, showing its potential for efficient and accurate litchi detection and counting in precision agriculture.
