Deep Hybrid Neural Models with Optimizers - Analysis for Multiclass classification in NLP

Harsh Sharma (~harsh444)


Description:

In Recent Advances in NLP, Multi-class classification has become an important task. It is based on textual data refers to a supervised machine learning task, where we try to predict a certain class for input data, given the input data in raw textual format. Well, thanks to TensorFlow, we have a variety of algorithms available to perform multi-class classification via natural language processing.

For any deep learning enthusiast, it's always a tedious task to know, which type of individual neural network along with a correct set of loss functions and optimizers can lead to the best performance of their models. Furthermore, a computational constraint might also impact their choices for selecting a neural network. Hence, I have been doing detailed research analysis and comparison of various hybrid combinations of deep neural networks and choosing different optimizer's impact on their learning rates for models, choosing suitable callbacks in TensorFlow while training of models for their performance with total time taken to train them. Therefore, I would like to propose a talk on this topic, which could help a lot of developers to derive insightful results on these hybrid deep neural networks. I would be explaining why to go for hybrid models, instead of individual neural networks and which adaptive and non-adaptive algorithms to go for while choosing the appropriate deep neural network, time taken by a hybrid model combination to train on GPU and non-GPU environment, and also the impact of loss functions on those models. I would be explaining it with the results I obtained using the Tensorflow framework.
