Building a word2vec model with our deep learning library in JavaScript

Welcome to the fifth part of out series, where we’ve been building a deep learning library in Javascript that mimics the core functions of popular frameworks like TensorFlow and PyTorch.

In the previous parts of the series, we’ve been implementing some basic functions needed to do this.

In the first part, we explored implementing an automatic gradient in JavaScript and also learned how to create some basic maths operations in JavaScript.

In the second part, we dove deep into implementing some of the core parts in building a neural network, such as tensors, linear layers, and ReLU and softmax activation functions.

In the part three, we discussed how to create a Sequential model, implement stochastic gradient optimization, and also implement cross-entropy loss.

And in the fourth part, we implemented visualization of our neural network graph.

In this part, we will be putting a lot of these pieces together to build a word2vec model using our library.

- Text pre-processing and cleaning (including skip-gram)
- Create a neural network for the word2vec model
- Create a function to obtain the word2vec of a word

**About: **Adversarial Robustness in Deep Learning is a session presented by Dipanjan Sarkar, a Data Science Lead at Applied Materials, as well as a Google Developer Expert in Machine Learning. In this session, he will focus on the adversarial robustness in the field of deep learning, where he talks about its importance, different types of adversarial attacks, and will showcase some ways to train the neural networks with adversarial realisation. Considering abstract deep learning has brought us tremendous achievements in the fields of computer vision and natural language processing, this talk will be really interesting for people working in this area. With this session, the attendees will have a comprehensive understanding of adversarial perturbations in the field of deep learning and ways to deal with them with common recipes.

**By Divye Singh**

**About: **Imbalance Handling with Combination of Deep Variational Autoencoder and NEATER is a paper presentation by Divye Singh, who has a masters in technology degree in Mathematical Modeling and Simulation and has the interest to research in the field of artificial intelligence, learning-based systems, machine learning, etc. In this paper presentation, he will talk about the common problem of class imbalance in medical diagnosis and anomaly detection, and how the problem can be solved with a deep learning framework. The talk focuses on the paper, where he has proposed a synergistic over-sampling method generating informative synthetic minority class data by filtering the noise from the over-sampled examples. Further, he will also showcase the experimental results on several real-life imbalanced datasets to prove the effectiveness of the proposed method for binary classification problems.

**By Dongsuk Hong**

**About:** This is a paper presentation given by Dongsuk Hong, who is a PhD in Computer Science, and works in the big data centre of Korea Credit Information Services. This talk will introduce the attendees with machine learning and deep learning models for predicting self-employment default rates using credit information. He will talk about the study, where the DNN model is implemented for two purposes — a sub-model for the selection of credit information variables; and works for cascading to the final model that predicts default rates. Hong’s main research area is data analysis of credit information, where she is particularly interested in evaluating the performance of prediction models based on machine learning and deep learning. This talk will be interesting for the deep learning practitioners who are willing to make a career in this field.

Deep Learning project for beginners – Taking you closer to your Data Science dream

Emojis or avatars are ways to indicate nonverbal cues. These cues have become an essential part of online chatting, product review, brand emotion, and many more. It also lead to increasing data science research dedicated to emoji-driven storytelling.

With advancements in computer vision and deep learning, it is now possible to detect human emotions from images. In this deep learning project, we will classify human facial expressions to filter and map corresponding emojis or avatars.

The FER2013 dataset ( facial expression recognition) consists of 48*48 pixel grayscale face images. The images are centered and occupy an equal amount of space. This dataset consist of facial emotions of following categories:

- 0:angry
- 1:disgust
- 2:feat
- 3:happy
- 4:sad
- 5:surprise
- 6:natural

Download Dataset: Facial Expression Recognition Dataset

Before proceeding ahead, please download the source code: Emoji Creator Project Source Code

We will build a deep learning model to classify facial expressions from the images. Then we will map the classified emotion to an emoji or an avatar.

In the below steps will build a convolution neural network architecture and train the model on FER2013 dataset for Emotion recognition from images.

Download the dataset from the above link. Extract it in the data folder with separate train and test directories.

Welcome to the third part of this series on building deep learning library in JavaScript from scratch.

In the first part of the series, we talked about the basic building blocks of all deep learning libraries—automatic gradients. Additionally, we showed how to implement autograd calculation in JavaScript.

In the second part of the series, We implemented tensors, math operations (`add`

and `matmul`

), a linear layer, and ReLU and softmax activation functions—put together, this gave us a very simple but working neural network.

In this part, we’ll pick up where we left off and implement the following;

- Sequential model
- Cross entropy loss
- Optimization

As a deep learning practitioner, I’ll again assume you’re familiar to some extent with Sequential models, both in Keras and TensorFlow. But for a quick reminder, you can check out the Keras sequential model here.

In the previous part of the series, we implemented a simple neural network:

```
let linear1 = new Linear(2,3)
let relu = new ReLU()
let linear2 = new Linear(3,2)
let softmax = new Softmax()
var x = new Tensor(1,2,require_grad=true)
x.setFrom([2,3]);
// forward pass
input = linear1.forward(x)
input = relu.forward(input)
input = linear2.forward(input)
output = softmax.forward(input);
console.log(output.out) // output = [ 0.5025667023096377, 0.4974332976903622 ]

```

Now, we’ll convert this model into a Sequential model that consists of different numbers of neural layers combined together to form a single model. The Sequential model has more to it than that—but we’ll be discussing that a bit later.
