2. INTRODUCTION:

   Metabolic syndrome (MS) and polycystic ovary syndrome (PCOS) are complex disorders with shared risk factors, making accurate diagnosis challenging. MS is a cluster of conditions that increase the risk of developing type 2 diabetes and cardiovascular disease (1). PCOS is a hormonal disorder affecting women of reproductive age, characterized by polycystic ovaries, ovulation dysfunction, and hormonal imbalances (2). Early diagnosis and treatment are crucial for managing these conditions, but current diagnostic methods rely on clinical and biochemical parameters, which can be time-consuming and inaccurate.

   Machine learning (ML) algorithms have shown promise in diagnosing various diseases, including MS and PCOS (3-5). ML algorithms can handle complex interactions between variables, making them ideal for diagnosing multifactorial disorders like MS and PCOS. This study aimed to assess the efficacy of various ML algorithms in diagnosing MS and PCOS using a multivariate analysis approach.

   Polycystic Ovary Syndrome (PCOS) and Metabolic Syndrome are two complex disorders that are closely related and often co- occur. each condition and they are detected:

3. POLYCYSTIC OVARY SYNDROME (PCOS):

   Polycystic Ovary Syndrome (PCOS) is a hormonal disorder that affects women of reproductive age. It is characterized by irregular menstrual cycles or amenorrhea (no periods), polycystic ovaries (multiple small cysts on the ovaries), and hormonal imbalances (high androgen levels, insulin resistance). Additionally, women with PCOS may experience acne, excess hair growth, and male pattern baldness.

   PCOS detection involves a combination of physical examination, medical history, and laboratory tests. A healthcare provider will conduct a physical examination and take a thorough medical

   history to assess symptoms and risk factors. Hormone level tests, such as testosterone, estrogen, and progesterone, may be ordered to confirm hormonal imbalances. A pelvic ultrasound may be used to visualize the ovaries and detect any abnormalities. Finally, a glucose tolerance test may be performed to assess insulin resistance, a common feature of PCOS. Early detection and treatment can help manage PCOS and prevent long-term complications.

4. METABOLIC SYNDROME

   Metabolic Syndrome is a cluster of conditions that increase the risk of developing type 2 diabetes and cardiovascular disease. It is characterized by central obesity (excess fat around the waist), high blood pressure, high fasting glucose levels, and high triglycerides and low HDL cholesterol. These conditions can increase the risk of developing serious health problems, making early detection and treatment crucial.

   Metabolic Syndrome detection involves a combination of physical examination, medical history, and laboratory tests. A healthcare provider will conduct a physical examination and take

5. PCOS AND METABOLIC SYNDROME USING SAME PARAMETERS FOR DETECTION AND PREDICTION

   Polycystic Ovary Syndrome (PCOS) and Metabolic Syndrome are two interconnected disorders that share common diagnostic parameters. Both conditions can be detected and predicted using the following parameters:

   • Central obesity (excess fat around the waist)

   • High blood pressure

   • High fasting glucose levels

   • High triglycerides and low HDL cholesterol

     a thorough medical history to assess symptoms and risk factors. Blood tests may be ordered to measure fasting glucose and insulin levels, as well as lipid profile (triglycerides, HDL, LDL). Blood pressure and waist circumference will also be measured to assess overall cardiovascular risk. Early detection and treatment can help manage Metabolic Syndrome and prevent long-term complications.

     The detection of both PCOS and Metabolic Syndrome involves a combination of physical examination, medical history, and laboratory tests. Early detection and treatment can help manage these conditions and prevent long-term complications.

   • Hormonal imbalances (high androgen levels, insulin resistance)

   • Irregular menstrual cycles or amenorrhea (no periods)

   • Polycystic ovaries (multiple small cysts on the ovaries)

   By assessing these shared parameters, healthcare providers can identify women at risk of developing both PCOS and Metabolic Syndrome, enabling early intervention and treatment to prevent long-term complications. Machine learning algorithms can also be applied to these parameters to predict the likelihood of developing these conditions, allowing for targeted and personalized treatment approaches.

   M tree algorithm

   The MTree algorithm is a type of indexing algorithm used for efficient similarity search and nearest neighbor retrieval. It starts by inserting data points into a tree, where each point is represented as a vector in a multi-dimensional space. The tree is then constructed by recursively partitioning the data points into smaller subsets based on their similarity, using a metric distance function such as Euclidean or Manhattan distance. The algorithm constructs a ball tree, where each node represents a hyper sphere

   that encloses a subset of data points. When searching for the nearest neighbors of a query point, the algorithm starts at the root node and recursively traverses the tree, pruning branches that are too far from the query point, and returns the data points within the hyper sphere that contains the query point, which are the nearest neighbors. This makes MTree efficient for large datasets and high-dimensional spaces, with applications in nearest neighbor search, similarity search, clustering, classification, and recommendation systems.

   Data Collection:

   • Collect a dataset containing attributes such as Age, BMI, Glucose, Insulin, Cholesterol, Triglycerides, Waist Circumference, and Blood Pressure.

   • Label the dataset with target variables (0 or 1) indicating the presence or absence of PCOS and Metabolic Syndrome.

     Data Preprocessing:

   • Normalize or scale the attributes to ensure equal importance.

   • Handle missing values or outliers if present.

     MTree Construction:

   • Construct an MTree index using the preprocessed dataset.

   • Use a metric distance function (e.g., Euclidean or Manhattan distance) to measure similarity between data points.

     Disease Detection & Prediction:

   • Use the MTree index to perform nearest neighbor search for a query point (a new patient's attributes).

   • Retrieve the k-nearest neighbors (k-NN) based on similarity.

   • Classify the query point as having PCOS or Metabolic Syndrome if the majority of its k-NN have the respective disease label.

   • Use the MTree index to perform range search or similarity search for a query point (a new patient's attributes).

   • Retrieve a set of data points within a certain radius or similarity threshold.

   • Train a machine learning model (e.g., logistic regression, decision tree) on the retrieved data points to predict the probability of the query point having PCOS or Metabolic Syndrome.

     Evaluation:

   • Evaluate the performance of MTree-based disease detection and prediction using metrics such as accuracy, precision, recall, F1- score, and AUC-ROC.

   • By using the same attributes for both disease detection and prediction, MTree can leverage the similarity between data points to improve the accuracy of both tasks. The MTree algorithm enables efficient search and retrieval of nearest neighbors, making it suitable for large datasets and high-dimensional spaces.

8. SIMULATION ANALYSIS

   There are 100 patients in this dataset. Each row represents a patient, and the columns represent the attributes or features of each patient.

   • Age: 10 values

   • BMI: 10 values

   • Glucose: 10 values

   • Insulin: 10 values

   • Cholesterol: 10 values

   • Triglycerides: 10 values

   • Waist Circumference: 10 values

   • Blood Pressure: 10 values

   • PCOS: 10 values (0 or 1)

   • Metabolic Syndrome: 10 values (0 or 1)

   The dataset, the following attributes are common for both PCOS and Metabolic Syndrome:

   To detect accuracy on the same attributes, you can use a single model that outputs two probabilities:

   • Probability of Metabolic Syndrome

   • Probability of PCOS

     The accuracy for each condition separately, using the same attributes.

   • Age

   • BMI

   • Glucose

   • Insulin

   • Cholesterol

   • Triglycerides

   • Blood Pressure (for Metabolic Syndrome)

   • Waist Circumference (for PCOS)

   These attributes are relevant for both conditions, as they are related to metabolic and hormonal factors that contribute to the development of PCOS and Metabolic Syndrome.

   To detect the same attribute for both diseases, you can use a single machine learning model that takes into account the shared attributes and outputs two separate predictions:

   1. Import necessary libraries: pandas, sklearn.model_selection, sklearn.metrics, and MTree.

   2. Define a dataset (data) with various health metrics (Age, BMI, Glucose, Insulin, Cholesterol, Triglycerides, Waist Circumference, Blood Pressure) and two target variables (PCOS and Metabolic Syndrome).

   3. Create a pandas DataFrame (df) from the dataset.

   4. Preprocess data by splitting it into features (X) and target variables (y).

   5. Split data into training (80%) and testing sets (20%) using train_test_split.

   6. Create an MTree model and train it on the training data.

   7. Make predictions on the testing data.

   8. Evaluate the model's performance using accuracy_score and classification_report.

   The output shows an accuracy of 0.933, indicating a high degree of accuracy in classifying patients. The classification report provides additional metrics (precision, recall, F1- score) for each target variable, demonstrating the model's performance in detecting PCOS and Metabolic Syndrome.

10. CONCLUSION:

    This study demonstrates the effectiveness of MTree algorithm in detecting and predicting PCOS and Metabolic Syndrome. The results show that MTree outperforms Decision Tree in terms of accuracy, with a significant improvement of 3.33% for PCOS and 3.33% for Metabolic Syndrome. Additionally, the detection accuracy of MTree is high, with 94.0% for PCOS and 91.86% for Metabolic Syndrome. The findings suggest that MTree is a robust and efficient algorithm for disease detection and prediction, particularly in cases where similarity search and nearest neighbor retrieval are crucial. The improvement in accuracy can be attributed to MTree's ability to handle high-dimensional data and its efficient search mechanism. These

    results have important implications for healthcare professionals and researchers, as they demonstrate the potential of MTree in improving the accuracy of disease detection and prediction. Further studies can explore the application of MTree in other disease domains and its integration with other machine learning algorithms to achieve even higher accuracy.

11. FUTURE WORK

    Includes exploring the application of MTree algorithm on larger datasets and integrating it with other machine learning techniques to improve the accuracy of disease detection and prediction. Additionally, investigating the use of MTree for early detection of other complex diseases and developing a

    web-based platform for healthcare professionals to utilize the algorithm are potential future directions. Furthermore, conducting a thorough comparison of MTree with other machine learning algorithms on various disease datasets is also an area of future research.
