+**GOOGLE Q AND A ANALYSIS**
+
+
+**GOAL**
+
+To build nlp based ml models for google question and answer dataset to specify category of device it predicts.
+
+**DATASET**
+
+https://www.kaggle.com/datasets/aashidutt3/google-devices-q-and-a-dataset
+
+**DESCRIPTION**
+
+To analyze question asked by customer along with device to predict which category problem falls onto wrt google dataset.
+
+**Visualization and EDA of different attributes:**

+
+
+
+**MODELS USED**
+1) Decision Tree 
+2) Random Forest
+3) Catboost
+4) Multivariate Logisitic Regression
+5) Gradient Boost
+6) Ridge
+7) MLP
+8) XGBoost
+
+**LIBRARIES**
+1) PANDAS
+2) NUMPY
+3) CATBOOST
+4) MATPLOTLIB
+5) OS
+6) SCIKIT-LEARN
+7) XGBOOST
+8) SPACY
+
+**IMPLEMENTATION**
+1) Loaded the dataset with 3 columns having 997 entries.
+2) Implementated EDA with visualisation using wordcloud to get estimate of important labels to be used later on for classification.
+3) Duplicate values were taken care of and text cleaning was implemented.
+4) Distortion score elbow for K-means was implemented.
+5) Tokenization and vectorization of textual data was implemented
+6) Model was trained efficiently with different machine learning algorithms
+
+
+**RESULT**
+1) Multivariate Logisitic Regression calculated exceptional accuracy of 0.86
+2) Rest of the models performed fairly well wrt to smaller database.
