title: Re-training a tensorflow model
body: <p>I am training a customized Named Entity Recognition <strong>(NER)</strong> model using <strong>NeuroNER</strong> which is written using tensor-flow.I am able to train a model and its performing well but when i am re-training it on new observation for which it showing incorrect result it correcting them but its <strong>affecting/forgetting some previous observation</strong> for which it showing correct results.</p>
