Ko'proq ko'rsatish📈 Telegram kanali Data science/ML/AI analitikasi
Data science/ML/AI (@datascience_bds) Ingliz til segmentidagi kanali faol ishtirokchi. Hozirda hamjamiyat 13 685 obunachidan iborat bo'lib, Texnologiyalar & Aralashmalar toifasida 9 380-o'rinni va Hindiston mintaqasida 31 607-o'rinni egallagan.
📊 Auditoriya ko‘rsatkichlari va dinamika
невідомо sanasidan buyon loyiha tez o‘sib, 13 685 obunachiga ega bo‘ldi.
10 Iyun, 2026 dagi oxirgi ma’lumotlarga ko‘ra kanal barqaror faollikka ega. Oxirgi 30 kunda obunachilar soni 143 ga, so‘nggi 24 soatda esa 2 ga o‘zgardi va umumiy qamrov yuqori darajada qolmoqda.
- Tasdiqlash holati: Tasdiqlanmagan
- Jalb etish (ER): Auditoriya o‘rtacha 8.09% darajada jalb etiladi. Nashrdan keyingi dastlabki 24 soatda kontent odatda umumiy obunachilar sonining 2.22% ini tashkil etuvchi reaksiyalarni to‘playdi.
- Post qamrovi: Har bir post o‘rtacha 1 106 marta ko‘riladi; birinchi sutkada odatda 304 ta ko‘rish yig‘iladi.
- Reaksiyalar va o‘zaro ta’sir: Auditoriya faol: har bir postga o‘rtacha 5 ta reaksiya keladi.
- Tematik yo‘nalishlar: Kontent panda, learning, row, api, ethic kabi asosiy mavzularga jamlangan.

Yuqori yangilanish chastotasi (oxirgi ma’lumot 11 Iyun, 2026 da olingan) sababli kanal doimo dolzarb va katta qamrovli bo‘lib qoladi. Analitika auditoriya kontent bilan faol hamkorlik qilishini, uni Texnologiyalar & Aralashmalar toifasidagi muhim ta’sir nuqtasiga aylantirishini ko‘rsatadi.
from nltk.tokenize import word_tokenize
text = "ChatGPT is awesome!"
tokens = word_tokenize(text)
print(tokens) # ['ChatGPT', 'is', 'awesome', '!']
4️⃣ Sentiment Analysis:
Detects the emotion of text (positive, negative, neutral).
from textblob import TextBlob
TextBlob("I love AI!").sentiment # Sentiment(polarity=0.5, subjectivity=0.6)
5️⃣ Stopwords Removal:
Removes common words like “is”, “the”, “a”.
from nltk.corpus import stopwords
words = ["this", "is", "a", "test"]
filtered = [w for w in words if w not in stopwords.words("english")]
6️⃣ Lemmatization vs Stemming:
- Stemming: Cuts off word endings (running → run)
- Lemmatization: Uses vocab & grammar (better results)
7️⃣ Vectorization:
Converts text into numbers for ML models.
- Bag of Words
- TF-IDF
- Word Embeddings (Word2Vec, GloVe)
8️⃣ Transformers in NLP:
Modern NLP models like BERT, GPT use transformer architecture for deep understanding.
9️⃣ Applications of NLP:
- Chatbots
- Virtual assistants (Alexa, Siri)
- Sentiment analysis
- Email classification
- Auto-correction and translation
🔟 Tools/Libraries:
- NLTK
- spaCy
- TextBlob
- Hugging Face Transformers
💬 Tap ❤️ for more!A lot of you actually participated in developing this, as backend devs, frontend devs or designers. 🧑💻That makes me insanely proud. This is truly built by us, for us. ❤️ I’m opening early access to a small group. If you want to be one of the first inside, test it, find bugs, suggest ideas, or just see what’s under the hood…join the Beta Testers Group 👉 https://t.me/+9vt9IKi6iGAxZDhk Let’s make this thing amazing. Together. 🚀
from tensorflow.keras.applications import MobileNetV2
model = MobileNetV2(weights="imagenet")
6️⃣ Object Detection:
Uses bounding boxes to detect and label objects.
YOLO, SSD, and Faster R-CNN are top models.
7️⃣ Convolutional Neural Networks (CNNs):
Core of most vision models. They detect patterns like edges, textures, shapes.
8️⃣ Image Preprocessing Steps:
- Resizing
- Normalization
- Grayscale conversion
- Data Augmentation (flip, rotate, crop)
9️⃣ Challenges in CV:
- Lighting variations
- Occlusions
- Low-resolution inputs
- Real-time performance
🔟 Real-World Use Cases:
- Face unlock
- Number plate recognition
- Virtual try-ons (glasses, clothes)
- Smart traffic systems
💬 Double Tap ❤️ for more!ollama run llama3.2
This command:
• Downloads the model
• Starts it locally
• Lets you chat instantly 💬
If you see the prompt, your local LLM is running.
⚙️ Step 3: Do local inference (API style)
Ollama runs a local server on your machine.
curl http://127.0.0.1:11434/api/generate \
-H "Content-Type: application/json" \
-d '{
"model": "llama3.2",
"prompt": "Explain overfitting like I am 12",
"stream": false
}'
If you get a JSON response with text → ✅ it works.
💡 Why this is powerful
• Works offline
• Private by default
• Perfect for learning, testing, and small apps
This is the easiest way to start with LLMs locally.from keras.models import Sequential
from keras.layers import Dense
model = Sequential()
model.add(Dense(64, activation='relu', input_shape=(100,)))
model.add(Dense(1, activation='sigmoid'))
5️⃣ Types of Deep Learning Models:
- CNNs → For images
- RNNs / LSTMs → For sequences & text
- GANs → For image generation
- Transformers → For language & vision tasks
6️⃣ Training a Model:
- Feed data into the network
- Calculate error using loss function
- Adjust weights using backpropagation + optimizer
- Repeat for many epochs
7️⃣ Tools & Libraries:
- TensorFlow
- PyTorch
- Keras
- Hugging Face (for NLP)
8️⃣ Challenges in Deep Learning:
- Requires lots of data & compute
- Overfitting
- Long training times
- Interpretability (black-box models)
9️⃣ Real-World Use Cases:
- ChatGPT
- Tesla Autopilot
- Google Translate
- Deepfake generation
- AI-powered medical diagnosis
🔟 Tips to Start:
- Learn Python + NumPy
- Understand linear algebra & probability
- Start with TensorFlow/Keras
- Use GPU (Colab is free!)
