Machine Learning in Frontend Development

What is Machine Learning by Examples?

Making computers able to identify cats or dogs or anything in an image. Making computers able to predict the future.

Some of Algorithms that makes it possible


  1. Naive Bayes
  2. K-Nearest Neighbour (KNN)
  3. Linear Regression
  4. Convolutional Neural Networks (CNN)
  5. LSTM - Long Short Term Memory

Types of Algorithms


  1. Supervised Learning
  2. Unsupervised Learning
  3. Reinforcement Learning

What is Supervised Learning?

Create predictive models based on a set of features and labels. Example, predicting price of a house based on other houses sold in the area. Features are characteristics of the entries in the dataset. Label would be the prices of the houses. Another example is customer clustering in a supermarket based on buying habits, time of buying, frequency, etc. Another example is sign language to text or speech conversion.
One of the ways to use supervised learning in frontend development is setting alt text of images, adding tags to content, etc.

Why Machine Learning in Javascript?

Because most frontend develoeprs are good at javascript. One can reduce time spent on learning a new language such as python and directly focus on Machine Learning. That helps faster prototyping.
How can Machine Learning be used in frontend?
  1. Import an existing pre-trained model
  2. Retrain an imported model (transfer learning)
  3. Define, train, and run mdoels entirely in the browser.

Tools

Libraries
  1. ML5
  2. Tensorflow.js
  3. Keras.js
  4. etc...
Cloud ML Providers
  1. GCP
  2. AWS
  3. Microsoft
  4. etc...
Here is an example of a frontend ML that I developed using a pre-trained model: https://weekay.herokuapp.com/api/faice

How to train a model?

Take 80% of the dataset and label them. And let the machine learning program assess the rest of the 20% of datset and label them. For this the program needs a algorithm model.

Limitations

  1. Machine Learning programs can take large amount of space, time, computation power, energy.
  2. Results from machine learning programs cannot be explained, so if in cases where explanation is required, there it could be tricky.
  3. Results can be morally unacceptable
  4. Results can be biased because of the data input

Difference between .exec() and .execPopulate() in Mongoose?

Here I answer what is the difference between .exec() and .execPopulate() in Mongoose? .exec() is used with a query while .execPopulate() is used with a document Syntax for .exec() is as follows: Model.query() . populate ( 'field' ) . exec () // returns promise . then ( function ( document ) { console . log ( document ); }); Syntax for .execPopulate() is as follows: fetchedDocument . populate ( 'field' ) . execPopulate () // returns promise . then ( function ( document ) { console . log ( document ); }); When working with individual document use .execPopulate(), for model query use .exec(). Both returns a promise. One can do without .exec() or .execPopulate() but then has to pass a callback in populate.

Python - List - Append, Count, Extend, Index, Insert, Pop, Remove, Reverse, Sort

🐍 Advance List List is widely used and it's functionalities are heavily useful. Append Adds one element at the end of the list. Syntax list1.append(value) Input l1 = [1, 2, 3] l1.append(4) l1 Output [1, 2, 3, 4] append can be used to add any datatype in a list. It can even add list inside list. Caution: Append does not return anything. It just appends the list. Count .count(value) counts the number of occurrences of an element in the list. Syntax list1.count(value) Input l1 = [1, 2, 3, 4, 3] l1.count(3) Output 2 It returns 0 if the value is not found in the list. Extend .count(value) counts the number of occurrences of an element in the list. Syntax list1.extend(list) Input l1 = [1, 2, 3] l1.extend([4, 5]) Output [1, 2, 3, 4, 5] If we use append, entire list will be added to the first list like one element. Extend, i nstead of considering a list as one element, it joins the two lists one after other. Append works in the following way. Input l1 = [1, 2, 3] l1.append([4, 5]) Output...

  Solution This article assumes you already have some confidence with  graph algorithms , such as  breadth-first search  and  depth-first searching . If you're familiar with those, but not with  topological sort  (the topic tag for this problem), don't panic, as you should still be able to make sense of it. It is one of the many more advanced algorithms that keen programmers tend to "invent" themselves before realizing it's already a widely known and used algorithm. There are a couple of approaches to topological sort;  Kahn's Algorithm  and DFS. A few things to keep in mind: The letters  within a word  don't tell us anything about the relative order. For example, the presence of the word  kitten  in the list does  not  tell us that the letter  k  is before the letter  i . The input can contain words followed by their prefix, for example,  abcd  and then  ab . These cases will never ...
