Next Word Prediction with NLP and Deep Learning

Wouldn’t it be cool for your device to predict what could be the next word that you are planning to type? This is similar to how a predictive text keyboard works on apps like What’s App, Facebook Messenger, Instagram, e-mails, or even Google searches. Below is an image to comprehend these predictive searches.

As we type in what is the weather we already receive some predictions. We can see that certain next words are predicted for the weather. The next word prediction for a particular user’s texting or typing can be awesome. It would save a lot of time by understanding the user’s patterns of texting. This could be also used by our virtual assistant to complete certain sentences. Overall, the predictive search system and next word prediction is a very fun concept which we will be implementing.

Note:_ This is part-2 of the virtual assistant series. There will be more upcoming parts on the same topic where we will cover how you can build your very own virtual assistant using deep learning technologies and python._

Deep Learning Vs NLP: Difference Between Deep Learning & NLP

When we think of Artificial Intelligence, it becomes almost overwhelming to wrap our brains around complex terms like Machine Learning, Deep Learning, and Natural Language Processing (NLP). After all, these new-age disciplines are much more advanced and intricate than anything we’ve ever seen. This is primarily why people tend to use AI terminologies synonymously, sparking a debate of sorts between different concepts of Data Science.

One such trending debate is that of Deep Learning vs. NLP. While Deep Learning and NLP fall under the broad umbrella of Artificial Intelligence, the difference between Deep Learning and NLP is pretty stark!

In this post, we’ll take a detailed look into the Deep Learning vs. NLP debate, understand their importance in the AI domain, see how they associate with one another, and learn about the differences between Deep Learning and NLP.

So, without further ado, let’s get straight into it!

Deep Learning vs. NLP

What is Deep Learning?

Deep Learning is a branch of Machine Learning that leverages artificial neural networks (ANNs)to simulate the human brain’s functioning. An artificial neural network is made of an interconnected web of thousands or millions of neurons stacked in multiple layers, hence the name Deep Learning.

Evolution of NLP : Introduction to Transfer Learning for NLP

This is the third part of a series of posts showing the improvements in NLP modeling approaches. We have seen the use of traditional techniques like Bag of Words, TF-IDF, then moved on to RNNs and LSTMs. This time we’ll look into one of the pivotal shifts in approaching NLP Tasks — Transfer Learning!

The complete code for this tutorial is available at this Kaggle Kernel


The idea of using Transfer Learning is quite new in NLP Tasks, while it has been quite prominently used in Computer Vision tasks! This new way of looking at NLP was first proposed by Howard Jeremy, and has transformed the way we looked at data previously!

The core idea is two-fold — using generative pre-trained Language Model + task-specific fine-tuning was first explored in ULMFiT (Howard & Ruder, 2018), directly motivated by the success of using ImageNet pre-training for computer vision tasks. The base model is AWD-LSTM.

A Language Model is exactly like it sounds — the output of this model is to predict the next word of a sentence. The goal is to have a model that can understand the semantics, grammar, and unique structure of a language.

ULMFit follows three steps to achieve good transfer learning results on downstream language classification tasks:

  1. General Language Model pre-training: on Wikipedia text.
  2. Target task Language Model fine-tuning: ULMFiT proposed two training techniques for stabilizing the fine-tuning process.
  3. Target task classifier fine-tuning: The pretrained LM is augmented with two standard feed-forward layers and a softmax normalization at the end to predict a target label distribution.

Using for NLP -’s motto — Making Neural Networks Uncool again — tells you a lot about their approach ;) Implementation of these models is remarkably simple and intuitive, and with good documentation, you can easily find a solution if you get stuck anywhere. Along with this, and a few other reasons I elaborate below, I decided to try out the library which is built on top of PyTorch instead of Keras. Despite being used to working in Keras, I didn’t find it difficult to navigate and the learning curve is quite fast to implement advanced things as well!

In addition to its simplicity, there are some advantages of using’s implementation -

  • Discriminative fine-tuning is motivated by the fact that different layers of LM capture different types of information (see discussion above). ULMFiT proposed to tune each layer with different learning rates, {η1,…,ηℓ,…,ηL}, where η is the base learning rate for the first layer, ηℓ is for the ℓ-th layer and there are L layers in total.

Weight update for Stochastic Gradient Descent (SGD). ∇θ(ℓ)J(θ) is the gradient of Loss Function with respect to θ(ℓ). η(ℓ) is the learning rate of the ℓ-th layer.

  • Slanted triangular learning rates (STLR) refer to a special learning rate scheduling that first linearly increases the learning rate and then linearly decays it. The increase stage is short so that the model can converge to a parameter space suitable for the task fast, while the decay period is long allowing for better fine-tuning.

Let’s try to see how well this approach works for our dataset. I would also like to point out that all these ideas and code are available at’s free official course for Deep Learning.

Deep learning on graphs: successes, challenges, and next steps

TL;DR This is the first in a [series of posts] where I will discuss the evolution and future trends in the field of deep learning on graphs.

complex social network

Deep learning on graphs, also known as Geometric deep learning (GDL) [1], Graph representation learning (GRL), or relational inductive biases [2], has recently become one of the hottest topics in machine learning. While early works on graph learning go back at least a decade [3] if not two [4], it is undoubtedly the past few years’ progress that has taken these methods from a niche into the spotlight of the ML community and even to the popular science press (with Quanta Magazine running a series of excellent articles on geometric deep learning for the study of manifoldsdrug discovery, and protein science).

Graphs are powerful mathematical abstractions that can describe complex systems of relations and interactions in fields ranging from biology and high-energy physics to social science and economics. Since the amount of graph-structured data produced in some of these fields nowadays is enormous (prominent examples being social networks like Twitter and Facebook), it is very tempting to try to apply deep learning techniques that have been remarkably successful in other data-rich settings.

There are multiple flavours to graph learning problems that are largely application-dependent. One dichotomy is between node-wise and graph-wise problems, where in the former one tries to predict properties of individual nodes in the graph (e.g. identify malicious users in a social network), while in the latter one tries to make a prediction about the entire graph (e.g. predict solubility of a molecule). Furthermore, like in traditional ML problems, we can distinguish between supervised and unsupervised (or self-supervised) settings, as well as transductive and inductive problems.

Similarly to convolutional neural networks used in image analysis and computer vision, the key to efficient learning on graphs is designing local operations with shared weights that do message passing [5] between every node and its neighbours. A major difference compared to classical deep neural networks dealing with grid-structured data is that on graphs such operations are permutation-invariant, i.e. independent of the order of neighbour nodes, as there is usually no canonical way of ordering them.

Despite their promise and a series of success stories of graph representation learning (among which I can selfishly list the [acquisition by Twitter] of the graph-based fake news detection startup Fabula AI I have founded together with my students), we have not witnessed so far anything close to the smashing success convolutional networks have had in computer vision. In the following, I will try to outline my views on the possible reasons and how the field could progress in the next few years.

**Standardised benchmarks **like ImageNet were surely one of the key success factors of deep learning in computer vision, with some [6] even arguing that data was more important than algorithms for the deep learning revolution. We have nothing similar to ImageNet in scale and complexity in the graph learning community yet. The [Open Graph Benchmark] launched in 2019 is perhaps the first attempt toward this goal trying to introduce challenging graph learning tasks on interesting real-world graph-structured datasets. One of the hurdles is that tech companies producing diverse and rich graphs from their users’ activity are reluctant to share these data due to concerns over privacy laws such as GDPR. A notable exception is Twitter that made a dataset of 160 million tweets with corresponding user engagement graphs available to the research community under certain privacy-preserving restrictions as part of the [RecSys Challenge]. I hope that many companies will follow suit in the future.

**Software libraries **available in the public domain played a paramount role in “democratising” deep learning and making it a popular tool. If until recently, graph learning implementations were primarily a collection of poorly written and scarcely tested code, nowadays there are libraries such as [PyTorch Geometric] or [Deep Graph Library (DGL)] that are professionally written and maintained with the help of industry sponsorship. It is not uncommon to see an implementation of a new graph deep learning architecture weeks after it appears on arxiv.

Scalability is one of the key factors limiting industrial applications that often need to deal with very large graphs (think of Twitter social network with hundreds of millions of nodes and billions of edges) and low latency constraints. The academic research community has until recently almost ignored this aspect, with many models described in the literature completely inadequate for large-scale settings. Furthermore, graphics hardware (GPU), whose happy marriage with classical deep learning architectures was one of the primary forces driving their mutual success, is not necessarily the best fit for graph-structured data. In the long run, we might need specialised hardware for graphs [7].

**Dynamic graphs **are another aspect that is scarcely addressed in the literature. While graphs are a common way of modelling complex systems, such an abstraction is often too simplistic as real-world systems are dynamic and evolve in time. Sometimes it is the temporal behaviour that provides crucial insights about the system. Despite some recent progress, designing graph neural network models capable of efficiently dealing with continuous-time graphs represented as a stream of node- or edge-wise events is still an open research question.
