An Ischemic stroke is expressed as lost neurological brain work because of the sudden loss of blood dissemination in the specific territory of the brain. The sub-acute ischemic stroke is the most basic illnesses reason for death on the planet. In this paper we utilize a hybrid way to deal with detecting the ischemic stroke from the alternate pathologies in magnetic resonance (MR) images utilizing Kernelized Fuzzy C-means (KFCM) clustering with adaptive threshold algorithm and the Support Vector Machine (SVM) classifier. In the existing method, the Otsu's method incorporated with SVM classifier method is utilized for the segmentation of the ischemic stroke image, but it has the limited accuracy 88%, specificity 66% and the sensitivity value is 94%. For the exact identification and segmentation the KFCM algorithm is utilized. The distance and the intensity of the lesion tissue is identified by this method. The accuracy and segmentation aftereffects of the classifier are measured in the testing and training phase by looking at the comparable and a decent variety of sample sets by considering diverse groupings. Our test comes about demonstrating that, the performance of the proposed technique is assessed in view of the precision, recall, sensitivity, accuracy and overlap metrics of the framework. Compared with the existing classification method, the proposed method has 17.64% RMSE (Root Mean Square Error), 6.24% MAPE (Mean Absolute Percentage Error) and 2.55% MBE (Mean Bias Error), consumption time is 6.45 (s) and also the sensitivity and the accuracy ranges are 98.8% and 99%. The proposed approach is actualized using MATLAB and the realtime datasets are used for our examination.
Background:
The sub-acute ischemic stroke is the most basic illnesses reason for death
on the planet. We evaluate the impact of segmentation technique during the time of breaking
down the capacities of the cerebrum.

Objective: The main objective of this paper is to segment the ischemic stroke lesions in Magnetic
Resonance (MR) images in the presence of other pathologies like neurological disorder, encephalopathy,
brain damage, Multiple sclerosis (MS).
Methods:
In this paper, we utilize a hybrid way to deal with segment the ischemic stroke from alternate
pathologies in magnetic resonance (MR) images utilizing Random Decision Forest (RDF)
and Gravitational Search Algorithm (GSA). The RDF approach is an effective machine learning
approach.
Results:
The RDF strategy joins two parameters; they are; the number of trees in the forest and
the number of leaves per tree; it runs quickly and proficiently when dealing with vast data. The
GSA algorithm is utilized to optimize the RDF data for choosing the best number of trees and the
number of leaves per tree in the forest.
Conclusion:
This paper provides a new hybrid GSA-RDF classifier technique to segment the
ischemic stroke lesions in MR images. The experimental results demonstrate that the proposed
technique has the Root Mean Square Error (RMSE), Mean Absolute Percentage Error (MAPE),
and Mean Bias Error (MBE) ranges are 16.5485 %, 7.2654 %, and 2.4585 %individually. The
proposed RDF-GSA algorithm has better precision and execution when compared with the existing
ischemic stroke segmentation method.
