Every excess tissue or impaired production of brain tissue in the human embryo is known as something of a tumor. Inside the brain, there may have been a tumor or any other orifice. Recognition of tumors and proper treatment at all times are still a difficult challenge. MRI devices are used mostly for the identification of specific tumors. MRI technologies are most often used for either the identification of specific tumors. Use artificial intelligence, medical diagnosis by imaging and machine learning is considered one of the many important issues for systems. Brain tumor evaluation generally requires greater accuracy, although small differences in assessment may turn to hazards. Because of this, the segmentation of both the tumor is a serious medical obstacle. Here proposed work introduces a hybrid machine learning-based tumor detection system (HMLBTD) for MR frames. The Fuzzy C-Means and K-Means Clustering Composite Clustering methodology have been used by the proposed HMLBTD frameworks and subsequently improved the classification of SVM and classification of normal and abnormal tumors. Across clustering, throughout order to achieve statistically valid performance, HMLBTD incorporates Fuzzy C-Means hybrid versions to achieve precision and K-means through segmentation. Throughout the second clustering step, HMLBTD employs Enhanced SVM (and use the ADA-boost framework with SVM) As well as the suggested HMLBTD strategy and also the proposed solution being implemented by utilizing different performance descriptive statistics using the MATLAB framework. An experimental study demonstrates that HMLBTD’s novel approach delivers higher yields than those of the traditional methods.

The Intrusion is a major threat to unauthorized data or legal network using the legitimate user identity or any of the back doors and vulnerabilities in the network. IDS mechanisms are developed to detect the intrusions at various levels. The objective of the research work is to improve the Intrusion Detection System performance by applying machine learning techniques based on decision trees for detection and classification of attacks. The methodology adapted will process the datasets in three stages. The experimentation is conducted on KDDCUP99 data sets based on number of features. The Bayesian three modes are analyzed for different sized data sets based upon total number of attacks. The time consumed by the classifier to build the model is analyzed and the accuracy is done.

mild cognitive impairment (MCI) is a condition between healthy elderly people and alzheimer's disease (AD). At present, brain network analysis based on machine learning methods can help diagnose MCI. In this paper, the brain network is divided into several subnets based on the shortest path,and the feature vectors of each subnet are extracted and classified. In order to make full use of subnet information, this paper adopts integrated classification model for classification.Each base classification model can predict the classification of a subnet,and the classification results of all subnets are calculated as the classification results of brain network.In order to verify the effectiveness of this method,a brain network of 66 people was constructed and a comparative experiment was carried out.The experimental results show that the classification accuracy of the integrated classification model proposed in this paper is 19% higher than that of SVM,which effectively improves the classification accuracy

The image analysis of the brain with machine learning continues to be a relevant work for the detection of different characteristics of this complex organ. Recent research has observed that there are differences in the structure of the brain, specifically in white matter, when learning and using a second language. This work focuses on knowing the brain from the classification of Magnetic Resonance Images (MRIs) of bilingual and monolingual people who have English as their common language. Different artificial neural networks of a hidden layer were tested until reaching two neurons in that layer. The number of entries used was nine hundred and the classifier registered a high percentage of effectiveness. The training was supervised which could be improved in a future investigation. This task is usually carried out by an expert human with Tract-Based Spatial Statistics analysis and fractional anisotropy expressed in different colors on a screen. So, this proposal presents another option to quantitatively analyse this type of phenomena which allows to contribute to neuroscience by automatically detecting bilingual people of monolinguals by using machine learning from MRIs. This reinforces what is reported in manual detections and the way that a machine can do it.

Vehicle-animal collisions represent a serious problem in roadway infrastructure. To avoid these roadway collisions, different mitigation systems have been applied in various regions of the world. In this article, a system for detecting animals on highways is presented using computer vision and machine learning algorithms. The models were trained to classify two groups of animals: capybaras and donkeys. Two variants of the convolutional neural network called Yolo (You only look once) were used, Yolov4 and Yolov4-tiny (a lighter version of the network). The training was carried out using pre-trained models. Detection tests were performed on 147 images. The accuracy results obtained were 84.87% and 79.87% for Yolov4 and Yolov4-tiny, respectively. The proposed system has the potential to improve road safety by reducing or preventing accidents with animals.
