Man, you are THE ONLY ONE explaining this intent type of neural net-based chatbot. Thanks a lot
Awesome content! when are we getting the biceps tutorial tho?
Some day maybe😂😂

Oh God. I need that tutorial ❤️
I love your videos! They're so useful :D I've just purchased your 7 in 1 book from amazon
Videos on neural network theory would be fantastic! Thanks again for another great video!
question, what kind of neural network architecture used here? Is it RNN?

sooo interested to the neural network theory!!! Love this channel so much, i've learned so much, thank you!!
I would love to see a video about the theory, great video, thank you:)
This is an amazing tutorial brother, thanks for all the knowledge you've shared! You earned a subscriber!
Thank you. Great commentary and clear explanations. Easy to follow how you built up the application. Perfect.
This was amazing! Thank you so much I have learned a lot :D
Hey bro, your programming style is sophistecated 🧑💻
Man, you are so underrated. I always search for simple examples of complex topics. After looking at your videos I am able to implement the basics in my projects easily

type it, lmao. @@mahnoorhome
Thanks 👍 I was actually waiting for this.
A much-needed updated vision of the chatbot from Tech with Tim. Love this video. From a viewer standpoint and someone who is coding along with you to program this thing. Either don't put a video of yourself on the screen, put it in the upper right-hand corner, or make it smaller. It's hard to code along with you as the camera of yourself blocks some of your code in the video.
This video is more explanatory and far better than the tech tim video, and the tech tim guy was just rushing,
question, what kind of neural network architecture used here? Is it RNN?
@@tomcat9761 No. It's a simple ANN

try watching the video
? - keras in "tensorflow.keras..." is not recognized by 'Pycharm', but it works anyway.
Changes:
- from tensorflow.keras.optimizers import SGD
+ from tensorflow.keras.optimizers.legacy import SGD
- training = np.array(training)
+training = np.array(training, dtype=object)
-sgd = SGD(lr=0.01, decay=1e-6, momentum=0.9, nesterov=True)

@@NeuralNine Hello, this error is returning: *lemmatize() missing 1 required positional argument: 'word'*
Can you make a series on neural network theory? This video was very helpful.Thanks
brother please do not stop! you are awesome
Well done. As I am new to chatbot() and python. Your video helped to fill in all the gaps in Tim video. Thanks brother.
Never seen this type of content before, really amazing
yeah, his tutorials are very applicable. i wonder what would happen to my knowledge if i carry one of that out each day for 1 month staright
Hi NeuralNine, this is a great piece. I would like to ask you if this tutorial would work for another language. Would it be enough to just edit intents, to comply with the language I would like to use? And the second question, do you have some tutorial, on how to implement this bot to streamlabs chatbot for twitch?
I tried it with german words and all I had to do is define the language in the word_tokenize function:
nltk.word_tokenize(pattern,language='german')
hey. where can i get source code? any idea?
Hey manx nice content, always excited when you post a new video
What is the difference between this and using something like the difflib SequenceMatcher library or the Levenshtein method, as in finding the similarity metric between the given input and a list of sentences and then picking the closest match as a response by looping through all the data one by one? Just tried it, and it works exactly the same but with a few lines of code, which brings me to the question why using AI for this is even necessary?
Bro You are one of the most Underrated YT channel I've ever seen..... Keep up the good work : - )
Man do i love that intro 🔥
Awesome tutorial, it worked right away! You definitely got me as a subscriber.
hey can u tell what extensions to download pls
Great video, I learned so much, thank you!
this tutorial is very useful! can I have the project source code for self-learning?
So...as far as the machine learning goes, it's just a text classification algorithm. I would love to see a version of this with actual text generation as well!
I mean it would be possible to combine it with the text generation tutorial I made some time ago ^^
@@NeuralNine Can't seem to find it!
@@SimonTiger I was hoping to find a comment like yours here. This may be the video he is referring to. ua-cam.com/video/QM5XDc4NQJo/v-deo.html
hey. where can i get source code? any idea?
@@NeuralNine YOU should really make that happen as a video!!!
22:08 Hi, i'm new to DL.. When we use Softmax, if there are (say)two outputs in the network, it will output probabilities like [.4 ,.6] or [.1, .9] or [.5, .5] etc right? (sum always 1).. so even if we enter some gibberish as input, there will always be some output(s) above error threshold of (say) .25.
How ill I tweak this so this won't happen? ( i mean if i enter "ahfliehf fsdlihfasdh" to bot, the outputs should be like something like [0.001, 0.00123])
Okay, this is the best tutorial on chat bots!! i can follow along! Quick question: Is it possible to show the "questions" as options to the user so that instead of typing, they choose from the options of questions instead?
i tried following Tech with Tim's but it was kinda hard.
20:42 very interested in the theory, I like how you explain and would be cool to hear it from you
I have to make one for school so this is perfect timing ;^)
Our school only do pascal bruh
Please put more videos like this bro, I needed some sorry more....
And if you are about to launch a video give a gif for that. That thrill will be enough for me to be happy. Don't get faded bro, we need you...

The video got really good but we don’t really clarify what packages to download. I know you said what at the beginning at Imports but it still gives me error messages with Tensorflow.
For example: '
To enable them in other operations, rebuild TensorFlow with the appropriate compiler flags. '
did you get it right??

As usual great video, excelent channel
UNDERRATED , u deserve a million sub
Hey, any idea how you'd get this to run with tflite?
Edit: Okay, I've gotten the model to run, but I realised nltk stemming is really slow. Is there a faster alternative?
(actually I'll try figure out exactly what's taking ages)
Edit #2: Nevermind, it all works, there's just a delay the first time the process is called for some reason (Which I'll try to trace and fix)
Thanks for the great tutorial, can't wait to setup my own personal assistant!
NIce video! Can you make an in-depth tutorial on making a friend-like chatbot that uses neural networks and NLP, and adapts it to modern libraries like Keras and TensorFlow? I've been making a project, but I've been having some issues.
Hey ...have u made the project?
Any progress?
Can you post a video on how to extract entities from intents and deploy the chatbot on a website or something. thanks
man I was just building a hard-coded chatbot, this vid came in the right time for me. thanks bro
@Hotdog_man2 Minecraft lol yea
Awesome work bro!
I like your videos
Kudos to you
I suggest you make a tutorial video on show to deploy an AI CHATBOT to back-end server to improve responsiveness and present more details.
When I added training data to the intents.json file, I got this error, anybody who can help?
ValueError: Input 0 of layer sequential is incompatible with the layer: expected axis -1 of input shape to have value 38 but received input with shape (None, 84)
I figured out that the 84 is just the amount of patterns in the intents.json file, but I haven't figured out why the input shape has to have a value of 38.
This helped me learn a lot about neural networks thanks!
Thanks for the Video Florian! 👏👏
it would be cool if you made a video where you combined a chatbot like this with/into a discord bot!
you'd just use discord.py to detect when a message is sent, use that message as the input for the AI, and output the AI's output as the discord message
@@owenknowles3796 didn't think about that thanks! Will try when computer switches on

Hi, i followed the tutorial and came across a glitch when it was time to train the bot.. I got the error: Error when checking input: expected dense_14_input to have shape (6,) but got array with shape (1,).. not sure what could be causing it
a series about NN/ ai in general would be dope
When will you open a Discord Server?
Amazing tutorial, thanks for the lesson.
Great work! I wonder is it possible to implement something like that bot would say "I didn't understand that" instead of still picking any random response. I set ERROR_TRESHOLD to higher number and then the bot just went back to wait for user's input but I want it to say that he didn't get what I was saying before going back.
Hi, great content! Although, is it possible for you to upload the code in your videos to a github repo? Thanks
That will be great!

@@NeuralNine Hey man for some reason whenever I say Hello or one of the greetings it says a goodbye response. Any idea why?
@@NeuralNine can i get the source code please
I'm trying to create a chatbot for customer care, it is going to be a live support agent for industries like Telecom companies, so after I finish with all the knowledge you have shared maybe I will have some questions and everything else.
Helpful, how would you do entity detection or extraction using neural networks ?
Hey NeuralNine, really like the videos.
Could you please like zoom in to the code... Or like increase the font. Its kinda difficult to see the code especially when not on full screen.
Even when youre showing other stuff like how to install mingw for c++... The text looks really small
But i really love your content and learn a lot. So if you could address that i'd be stoked
on mobile just reverse pinch the video to zoom
Can you please provide the files of the bot
(because mine didn't worked)
hello, your video is very useful. can I ask about whether the AI of a chatbot can carry out the learning process when it is running?? because I'm currently in a chatbot creation project with the Learning Agent method where the chatbot must be able to carry out the learning process while it's running, can this be done? Please help
Are you ever going to make a tutorial on a chatbot that generates its own responses?
and this is how my creator came to life.
Works great! Im having this error when adding more than 3 intents though.
ValueError: Input 0 of layer sequential is incompatible with the layer: expected axis -1 of input shape to have value 27 but received input with shape [None, 30]. :/

Can the response from the bot be replaced with sound or video or maybe it can be replaced by opening an application such as Google's assistant system?
Well, I followed along and as I ran it....this guy decided to reply "Hello" with "Talk to you later" LMAOO 😭Even a bot isnt interested in talking with me 😒
my bot keeps saying the intent is goodbye even if I say "how are you?" it says hey or goodbye or talk to you later
I have similar problem.
my bot keeps saying "hi", ""hello", "what can i do for you", even if i ask "what is your name"
please help
If there’s nothing wrong with the preprocessing you probably have to find a way to properly tune the model with a test set and a training set to prevent under or overfitting.
Hey, I have a Problem after training , type error in last 2 functions, While true, get_response
If you guys keep getting goodbye messages for other things change the error_threshold to 0.5 and if that doesn't work change the epochs in training.py to 800
hell yeah, my first AI. Thanks, man
This video is really great and this AI projects series is extraordinary
Hello... i have tried to copy your code now in 2023 and apparently there is an issue with training = np.array(training) since the [bag, output_row] columns don't have the same dimensions (maybe I have copied something wrong along the way...).
I have came up with a solution that bypass the issue, although its quite a caveman style solution and I do not have the knowledge to understand its consequences, but it does not crash the code and allows me to train the chatbot.
solution:
when defining the dimensions of:
output_empty = [0] * len(classes)
instead do:
output_empty = [0] * len(words)
this way the dimensions of "bag" and "output_row" are the same. (It will fill the space with 0, so it shouldn't change the bot training accuracy... but what do I know :D )

@@maxmayer3551 Would you rather trust an article or the official TensorFlow GitHub and PyPi? I've been able to run TensorFlow on python 3.8. There must be some other problem with your PC since it works with 3.8 on mine.
Hi, how would you code the condition, lets say if threshold is 0.7 and anything that is below, the chatbot would response smth like "I dont understand, please rephrase" ?
Very excellent work and Good amount of stuff there in for a beginners to have. I am learning Paython now.
can i have the source code?
Give us the source code plsss
No
@@Vincenzo_Cassano Yes?
No
@@Vincenzo_Cassano Yes??
This was very helpful. But I want to ask question. What should I do if I want to ask this bot a series of related questions. I am inputting user information inside a table and want to ask them their particulars. How should I proceed forward?
For anyone having issues with the model not running. change train_x and train_y into a tensor and adjust the input shape of the model to be 15, 5
what do you mean by change them into a tensor
can you share the code?
I am new to channel and you are doing such a good word, THANK YOU SO MUCH.
I am watching your Simple Mail Client video and I listen the intro music did you tell me what is the name of it??
Can you tell me if this is a top-down approach or bottom-up approach? Do you have a video on the other (if this is Bottom-up or Top-down)?
I learned a lot through this video. However since we have static replies for this exact project I believe that splitting the string from the user input into a list as you did, finding a key word and thus give the reply could be easily and faster done with if else statements. I get the educational manner for the AI part but because you didn’t exactly analyze the code that you used in the machine learning part because of the purpose of the video I will stick to my opinion having the thought of the purpose of the video being “build a chatbot” and not “use ai to create something”. Great video though❤
how do you test and validate this? What is your score? I tried validating it but the loss and accuracy are bad. Tried regularization techniques and I added more data. Still bad. Im guessing it is from how the data was stored. Do you know what is the reason behind this?
So ive checked he full video 3 times, gone through every line of code, but when i enter the first input text, i get alueError: Input 0 of layer "sequential" is incompatible with the layer: expected shape=(None, 0), found shape=(None, 23). how is that possible? any ideas? Great video btw!
Hello, that's great work you're good dude but I need the ia to respond with all accents on the letters like "é" or "ç". Any idea of how i could do ?
Love this but I think Levenshtain Distance fits better when doing small projects.
Thanks, this video helped me a lot!
How can i get some dynamic responses hitting an external API and provide in my chat response using placeholder or appending with the responses in intent json
Question: Can you make it/How can you make it so that if you say something ex: "Hello" it searches for the word on the internet and puts it in a group ex: "Greetings" and learn when to use it? I think that would be faster than writing the sentences you might say and responses for it and more effective (once it learns the vocabular). Oh yeah, or just "scan" the entire vocabular. Sounds like something from a movie but I think it's very possible to do it, probably takes a lot of coding tho.
bro your intro is fire
