hey @Jan19LPN0013,
there are various other techniques to improve accuracy on a particular dataset :

  1. feature selection and extraction
  2. scaling data
  3. selecting correct model technique:
    a. basic models like linear regression , logistic regression
    b. bagging or boosting ensemble techniques
    c. Neural networks
  4. Hyper parameter tuning

If you work in the correct order , with the best model you can easily achieve 95-97% accuracy on the given dataset.

I hope this would have helped you.
Thank You and Happy Learning :slightly_smiling_face:.
