Abstract - As a result of increased strain and stress in their daily routines, people are experiencing behavioral problems and intellectual health challenges. There are distinct types of mental disorders, including pressure, bipolar disorder, unhappiness, schizophrenia and many more. Mental disorientation can have a variety of physical and localized negativerepercussions. This projectwillidentifypsychological instability in the context of the experiences and emotions that a person is having. Fits of worry, sweating, heart palpitations, anguish, anxiety, overthinking imaginations, and deceptions are signs of mental illness, and each side effect reveals something about the type of dysfunctional behavior. Mental illness is accompanied by both physical and emotional symptoms. This study will establish whether or not an individual is facing from mental disorder based on their actions andthoughts. Four AI algorithms are used inthistask: Support Vector Machine, Logistic Regression, Decision Tree, KNN and XGBoost. In addition to previous pre-processing techniques, we usedanadditionaltree classifier inthis review as a component determination method. An AI computation was usedtoanalyses a psychologicalmaladjustmentinlightof the person's side effects after applying the component choice approach. Using the Recall, Accuracy, Precision, and F1-score bounds, AI model suitability was assessed.

2. LITERATURE REVIEW
Manyresearcheshavebeencarriedoutforanalyzingwhich methodoftreatmentisbestforthementalillness.Someof thethemareasfollows.
Ifapatienthasbeenmisdiagnosedthenitmayleadtosevere degration of mental health of the patient. These misdiagnosis may even lead to death of the patient. About millionsofpatientsaremisdiagnosedaroundtheworld.In this research work, a report is generated using semirobotized framework which guides the starter in the prediction of the particular treatment. This makes work easier for the professionals. There will be a classifier or a mentalexaminertoassisttheminthisprocess[1].
Mental health problems not only impact on the patient's behaviorbutalsotheirfamilyandthesociety.Thesepatients needtocommunicatewiththeotherswhohavebeenalready diagnosed. This may be through online communication or personal interaction. Mental illness may be caused due to mixedsituations.Forexample,ifapersonissufferingfrom nervousnessdisorderthenitmayleadtosadnessinhislife. These mixing of mental disorders are the spotlight of our work that is creation of web networks which prompt a preciseforecastofthemisery[2].
In this research work, the focus is mainly on treating the children's abnormal behavior. Mental health problems shouldbetreatedinearlystagebeforeitgetsworse.Inthis process, eight algorithms are taken into considerations. Thesealgorithmsaretestedonsixtydifferentcases.Among theseMultilayerPerceptron,MulticlassClassifierandLAD Tree are to be accurate with slight difference in their performance[3].
Personality prediction is the analysis of a personality by monitoring the response of an individual to various situations.ThisiscarriedoutbythehelpofBigFiveModel whichisalsoknownasOCEAN.Asthisresearchworkdeals withlargedataset,Multimodal isbestsuitablemethodfor thistaskwhichishelpfulinevaluatingbothverbalaswellas non-verbalfeatures[4].
