Chatbots are computer programs designed to mimic human conversation and interact with people through various communication channels such as messaging apps, websites, and mobile apps. Chatbots are everywhere and frustrating as most of them never solve customer problems. In recent years, there has been a significant advancement in the capabilities of chatbots, particularly in the realm of artificial intelligence (AI) and machine learning (ML). These advanced chatbots, also known as conversational AI, use interconnected "neurons" or nodes to process and analyze data, much like the human brain.

As chatbots continue to evolve and become more sophisticated, they have the potential to revolutionize the way businesses interact with their customers and streamline various processes. In this article, we will explore the advancements made in chatbot technology and discuss future directions for chatbots in various industries.

**## How Advanced Chatbots Work:**

Recently chatbots use natural language processing (NLP) and machine learning algorithms to understand and respond to user input. As the chatbot is exposed to new data and experiences, it is able to learn and adapt to new situations. It can recognize patterns in the data and use this information to make predictions and recommendations.

One key component of advanced chatbots is the use of "neurons" or nodes that are connected in a network. These neurons are responsible for processing and analyzing data and are inspired by the structure of the human brain. They can learn to recognize patterns in data and make predictions about what should come next.

## **How are chatbots trained to be intellectual?**
 
In advanced chatbots, the above-mentioned neurons are organized into layers, with each layer performing a specific function. For example, the input layer may process raw data, such as text or voice input from the user. The hidden layers may analyze this data and extract relevant information, and the output layer may generate a response based on the information gathered from the input and hidden layers.
As the chatbot processes more and more data, it can learn to identify patterns and make more accurate predictions about what should come next in a conversation. This can allow the chatbot to become more adept at simulating human conversation and providing helpful responses to users.

For example, if a chatbot is trained on customer service inquiries, it may be able to identify patterns in user queries and predict the most appropriate response. For example, if a user asks, "How do I return a product?" the chatbot may recognize this as a common customer service inquiry and provide the appropriate response, such as "To return a product, please follow the steps outlined in our return policy."

In addition to NLP and machine learning algorithms, advanced chatbots may also use other AI techniques such as decision trees, rule-based systems, and deep learning to improve their
 ability to understand and respond to user input.

_Here is an example of how to build a conversational AI chatbot:_

**1. Collect and clean data:** First, gather a large dataset of conversational data that will be used to train the chatbot. This can include real conversations between humans, or simulated conversations created specifically for the chatbot. Once you have the data, clean and preprocess it to remove any noise or inconsistencies.

**2. Choose a machine learning algorithm:** There are several algorithms that can be used to build a chatbot, including decision trees, random forests, and neural networks. Choose the algorithm that best fits the needs of your chatbot and the data you have collected.

**3. Train the chatbot:** Use the cleaned and preprocessed data to train the chatbot using the chosen machine learning algorithm. This will involve feeding the data into the algorithm and adjusting the parameters to achieve the best results.

**4. Test and evaluate the chatbot:** Once the chatbot is trained, test it using a separate dataset to see how well it can respond to different types of conversations. Use this data to further fine-tune the chatbot and improve its performance.

**5. Deploy the chatbot:** Once you are satisfied with the chatbot's performance, deploy it to a platform where it can be used by users. This could be a chat application, website, or mobile app.

**6. Monitor and update the chatbot:** Regularly monitor the chatbot's performance and make updates as needed to improve its accuracy and response times. This may involve adding new data to the training dataset or adjusting the machine learning algorithm.

_Here is a sample code for building a chatbot:_

```
import nltk
import re
import numpy as np
import pandas as pd
from sklearn.feature_extraction.text import CountVectorizer from sklearn.model_selection import train_test_split
from sklearn.naive_bayes import MultinomialNB
from sklearn.metrics import accuracy_score

#Preprocessing functions

def process_text(text):

# convert to lowercase

text = text.lower()

# remove punctuation

text = re.sub(r'[^\w\s]', '', text) # remove numbers
text = re.sub(r'\d+', '', text)

# tokenize

tokens = nltk.word_tokenize(text) # remove stopwords
stopwords = nltk.corpus.stopwords.words('english')
tokens = [token for token in tokens if token not in stopwords] 

# lemmatize

lemmatizer = nltk.stem.WordNetLemmatizer()
tokens = [lemmatizer.lemmatize(token) for token in tokens] # join tokens into single string
text = ' '.join(tokens) return text

#Load Data
data = pd.read_csv('conversations.csv') data['text'] = data['text'].apply(process_text)

#create feature matrix and target vector
vectorizer = CountVectorizer()
X = vectorizer.fit_transform(data['text']) y = data['label']

#split data into train and test sets

X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2, random_state=42)

#train model

model = MultinomialNB() model.fit(X_train, y_train)

#evaluate model

y_pred = model.predict(X_test)
score = accuracy_score(y_test, y_pred) print(f'Model accuracy: {score*100:.2f}%')

#define chatbot functions

def classify_text(text):
text = process_text(text)
text = vectorizer.transform([text]) label = model.predict(text)[0] return label
def respond(text):
label = classify_text(text)

if label == 'greeting':
return 'Hello! How are you today?'
elif label == 'goodbye':
return 'Goodbye! Have a great day.'
elif label == 'question':
return 'I am here to answer your questions. What do you want to know?' else:
return 'I am sorry, I am not sure how to respond to that.' 

#test chatbot

print(respond('Hello, how are you?')) 
print(respond('What is the weather like today?'))
print(respond('Goodbye!'))
```
