	<abstract>&lt;strong&gt;Background&lt;/strong&gt;: Diabetic retinopathy (DR) is a leading cause of blindness, and DR progression can be avoided by early dot hemorrhage (DH) detection. &amp;nbsp;Manual diagnosis is frequently subjective and time-consuming, which emphasizes the necessity for automated methods.&lt;br&gt;
&lt;strong&gt;Methods&lt;/strong&gt;: Using machine learning (ML) and artificial intelligence (AI), this study suggests an automated DH detection system. After preprocessing retinal fundus images with contrast limited adaptive histogram equalization (CLAHE), a modified VGG-16 convolutional neural network (CNN) was used to extract features. Support vector machine (SVM), random forest (RF), and linear regression (LR) models were used to classify both local and global features.&amp;nbsp;&lt;br&gt;
&lt;strong&gt;Results&lt;/strong&gt;: The proposed approach is highly effective in detecting and classifying DH associated with DR. When tested on the APTOS dataset, the model obtained an overall accuracy of 93.26% for DH identification and classification. This shows that the CNN is extremely effective in learning the distinguishing characteristics of hemorrhagic lesions from retinal fundus images. To confirm the suggested approach&amp;rsquo;s efficiency, comparative research was carried out using three traditional ML algorithms: RF, SVM, and LR. Among them, the RF classifier had the greatest accuracy of 92.4%, surpassing both SVM and LR.&amp;nbsp;&lt;br&gt;
&lt;strong&gt;Conclusion&lt;/strong&gt;: The research introduces a VGG16-based CNN that detects retinal hemorrhages in the APTOS dataset with an accuracy of 93.26%. Experimental results show that the Leaky ReLU activation function improves image classification performance, whereas the Adam and Adadelta optimizers consistently improve CNN-based learning. Finally, the research showed that deep learning-driven dynamic image analysis is a reliable and effective method for automated identification and categorization of DH, paving the way for early and accurate DR screening systems.&lt;br&gt;
