How?

It's way easier than you think, we all know that AI can do most of the job you wants, if I want to be more specific Deep learning can do most of the job we want

Now you may think what is that most of the job means? 🤔

  • Self-Driving Cars
  • News Aggregation and Fraud News Detection
  • Natural Language Processing
  • Virtual Assistants
  • Entertainment
  • Visual Recognition
  • Fraud Detection
  • Healthcare
  • Personalizations
  • Detecting Developmental Delay in Children
  • Colorisation of Black and White images
  • Adding sounds to silent movies
  • Automatic Machine Translation
  • Automatic Handwriting Generation
  • Automatic Game Playing
  • Language Translations
  • Pixel Restoration
  • Photo Descriptions
  • Demographic and Election Predictions
  • Deep Dreaming

These things are considered to be the top 20 applications that AI(deep learning) can do in 2022

which is mind-blowing compared to like just 10 years ago most of the stuff mentioned here is impossible to understand by computers

So said that most of us think Then it's going to be done only by scientists right? or Ph.D. professors right?

No and No🙅‍♂️

You don't have to be a Ph.D. student to build this

Well I'm not a Ph.D. student, I'm actually a 18 year's old college student who is currently doing a BSc computer science degree in India (which has nothing to do with Machine Learning or the AI field actually!😅)

And we are going to get a state of the art result on this problem at least for now (the machine learning and deep learning field is always going to growalways learning😇) by just understanding the fundamentals of Deep learning

It's again not that complicated then you think

once you get the fundamentals down its going to be really a fun ride 🥳

We are literally teaching Our Computer to learn

Said that,

Well it does contains math

But how much math is it? It contains only three branches in math

  • Calculus
  • matrix multiplications
  • Linear Algebra

I don't know about you But I hated math classes in our schools

via GIPHY

But the catch is math is an art

Just like in this picture if you first saw this it's definitely going to trip your mind(considering that you have never seen this picture before)

Because you're not going to see this kind of pose posted by your friends or even you

It's the same when it comes to math

If you want to create anything math is going to be your friendly neighborhood buddy🐎

This is the only book that made me rethink Maths which is written by Paul Lockhart A Mathematician’s Lament

If you had time just consider checking this out it's really a great book that going to change most of our thought about maths And in bonus, it contains only 25 pages 🥳

Ok, let's finally get into the main topic that we are going to cover Can we teach an AI to understand how plants look?

The answer is

Yes, We Can!

Let's do this 👀

pexels-pavel-danilyuk-8438918.jpg

First, let's get our data from Kaggle

Which is

Agriculture-crops

here it contains as that name describes Agricultural crops if I wanted to be specific ['maize', 'jute', 'wheat', 'sugarcane', 'rice'] these four classes(plants) pictures

Our problem is To teach an AI model to understand the plants and predict which one is mazie and which one is wheat and so on..

Getting our data ready🍃

If you saw my blogs then you know it SPLITTING our data into Train and Validation sets

Code :

train_dir = "/content/kag2/"
valid_dir = "/content/crop_images"

train_data = tf.keras.preprocessing.image_dataset_from_directory(train_dir,label_mode="categorical",image_size=(224,224))
valid_data = tf.keras.preprocessing.image_dataset_from_directory(valid_dir,label_mode="categorical",image_size=(224,224),shuffle=False)

Now we have data let's build our AI

Creating MARK AI🤖

pexels-tara-winstead-8386434.jpg

We are going to leverage TransferLearning Model if you don't know about it🤔 I just made a recent blog post if you wanted to check it out here :-> common click me it's going to be fun😙

Said that...let's create our mark_ai🤖

Code:

base_mark = tf.keras.applications.EfficientNetB0(include_top=False)
base_mark.trainable=False

input = tf.keras.layers.Input(shape=(224,224,3))

x = base_mark(input)

pool = tf.keras.layers.GlobalAveragePooling2D()(x)

output = tf.keras.layers.Dense(len(class_names),activation="softmax")(pool)

mark = tf.keras.Model(input,output)
mark.compile(loss="categorical_crossentropy",optimizer="adam",metrics="accuracy")
mark.summary()

Output :

Screenshot 2022-08-16 171506.png

Now we have a model let's give our training data and validation data to train our model

Code:

mark_history = mark.fit(train_data,epochs=5,steps_per_epoch=len(train_data),
                          validation_data=valid_data,validation_steps=int(0.15*len(valid_data)))

Output :

Screenshot 2022-08-16 171708.png

!Wow 🤯 our Mark AI got an accuracy of 96% which is in humans term(10 out of 9 images are going to be correct)

Which is really really great and the power of transfer learning 😎

Let's measure our model's performance🧐

Evaluation of our AI

Let's look at the loss and accuracy of our model

loss: how bad is our model prediction compared to our original data we always need less loss

Accuracy: how accurate is our model with the prediction compared to our original datawe always need more accuracy

LOSS :

Screenshot 2022-08-16 172128.png

Accuracy :

Screenshot 2022-08-16 172358.png

As we can see the loss is decreasing as we expected and accuracy is increasing(as shown in the model training output)

Confusion_Matrix

Let's find out where our model got confused

Screenshot 2022-08-16 173657.png

As we can see our Mark AI got confused mostly in this area's

Mark_1 AI

Let's create another model(Mark_1) and improve our first_model(Mark) result by just adding a single dense layer

Code :

base_mark = tf.keras.applications.EfficientNetB0(include_top=False)
base_mark.trainable=False

input = tf.keras.layers.Input(shape=(224,224,3))

x = base_mark(input)

pool = tf.keras.layers.GlobalAveragePooling2D()(x)

dense_layer = tf.keras.layers.Dense(500,activation="relu")(pool)#newly added line

output = tf.keras.layers.Dense(len(class_names),activation="softmax")(dense_layer)

mark_1 = tf.keras.Model(input,output)
mark_1.compile(loss="categorical_crossentropy",optimizer="adam",metrics="accuracy")
mark_1.summary()

Output :

Screenshot 2022-08-16 174043.png

As we can see our newly added layer let's look at the result

Code :

mark_1_history = mark_1.fit(train_data,epochs=5,steps_per_epoch=len(train_data),
                          validation_data=valid_data,validation_steps=int(0.15*len(valid_data)))

Output :

image.png


Wowie, Damn😱 our model has an accuracy of 1.0 which is as you guessed it 100%

By just adding a single line to our Mark AI model we got an accuracy that is considered of state of the art result😎


But let's not stop here let's see the evaluation and predicts with the Mark_1 AI

Confusion_matrix

image.png

As we can see no error here it predicted every plant right

Let's visualize and predict some plants that have never been seen before

prediction

image.png

Here our model is saying that it's rice and it is 51% sure

Well it is indeed rice

Let's look at another example

image.png

Again here our model is saying that it's wheat and it is 100% sure

And we can go on for a while by doing this...

App version

And If you wanted to check this out on your own I created an app with a help of HuggingFace and you can check this out here:->-> click me I ( ̄︶ ̄)↗ 

🎯 If you are using a PC while viewing this app you can directly open google in the next tab and drag plant's images from there and drop it on the drop section of the app 🎯

Well, there you go ... we build a model which can classify our plants easily 😎

Well Thank-you very much for your time (ಥ _ ಥ)

Bye (^▽^)┛
