What is this dataset? The Student Sleep, Screen Time & Academic Performance dataset contains information about students’ lifestyle habits (sleep duration, sleep quality, screen time, study hours) and their academic performance (GPA or test scores). Each row is one student. It’s perfect for learning ML because it combines lifestyle predictors with an outcome variable — exactly the kind of real-world problem ML solves.
What is KaggleHub? Kaggle is a website where people share datasets for machine learning. KaggleHub is a Python library that lets you load those datasets directly into your code with one line — no manual downloading.
What is a DataFrame? A pandas DataFrame is like an Excel spreadsheet inside Python. It has rows (one per student) and columns (sleep hours, screen time, GPA, etc.). The variable df we create here holds all the student data.
Why check shape, head(), info(), describe()?
df.shape→ How many rows (students) and columns?df.head()→ Show the first 5 rows so you can see column names and sample valuesdf.info()→ What type of data is in each column? (text vs. numbers) How many missing values?df.describe()→ Basic statistics: mean sleep hours, mean screen time, mean GPA, min, max
Important: The file_path is the CSV filename inside the dataset. Visit the Kaggle dataset page → Files tab to find the exact filename. Also, check df.head() to identify the exact column name for academic performance — it might be called gpa, academic_score, performance, or something else. The code in Step 3 auto-detects it.

Before any model touches the data, we visualize distributions, plot sleep/screen time vs. academic performance, and check correlations.
What is EDA? Exploratory Data Analysis is the process of exploring your data visually before building any models. It’s like reading a nutrition label before eating — you want to know what you’re working with.
What is a histogram? A histogram counts how many students fall into each range. For example, how many students sleep 5–6 hours, how many 6–7, etc. The KDE curve (smooth line on top) estimates the overall shape.
What is a scatter plot? A scatter plot places each student as a dot, with one variable on the x-axis and another on the y-axis. Plotting Sleep Hours vs. GPA reveals whether students who sleep more tend to perform better — the core question of this dataset.
What is correlation? Correlation measures how strongly two variables move together, from -1 to +1. If sleep hours and GPA correlate positively (above 0.3), it means students who sleep more tend to get higher GPAs. If screen time and GPA correlate negatively, more screen time means lower GPA. The heatmap shows all pairwise correlations at once.
Why does EDA matter? The scatter plots will reveal whether the relationship between sleep/screen time and academic performance is linear (a clear trend) or noisy (scattered with no clear pattern). This tells you whether to expect high or low R² from your models.

plt.show()Encode, engineer, scale — without leakage.
Handle missing values, encode categorical features, create a high vs. low performer target, and scale features.
Why do we need preprocessing? Machine learning models only understand numbers. If the dataset has text columns (like gender or school type), we need to convert them to numbers. Also, some rows might have missing values that need to be handled.
Handling missing values: We use dropna() to remove rows with missing data. If the dataset has many missing values, you might want to fill them with the mean or median instead — but for most student lifestyle datasets, dropping is fine.
Label encoding for categorical features: We use LabelEncoder to convert text columns (if any) to numbers. Example: Male=0, Female=1 or School A=0, School B=1.
What is a target variable? For regression, the target is the academic performance column (GPA, score, etc.). For classification, we create a high_performer target: 1 if performance ≥ median, 0 if below. This splits students into “high performers” and “low performers.”
What is train/test split? We divide data into 80% for training and 20% for testing. random_state=42 makes the split reproducible.
What is scaling? Standardization rescales every feature so mean=0, std=1. This matters because sleep_hours might range from 3–10 while screen_time ranges from 0–12 — without scaling, features with larger ranges would dominate.
What is data leakage? When information from the test set accidentally influences training. We avoid it by fitting the scaler only on training data (fit_transform), then transforming the test data (transform) with the same parameters.

No data leakage.Five scikit-learn models,
two tasks.
For each task — predict academic performance (regression) and classify high vs. low performer (classification) — we train five models.
What is supervised learning? Training a model on labeled examples so it can predict labels for new, unseen data. Two types:
- Regression: predict a continuous number — e.g., “this student will have a GPA of 3.6”
- Classification: predict a category — e.g., “this student is a high performer (1) or low performer (0)”
The five models, explained simply:
- Linear Regression: draws the best-fitting straight line through the data. Simple, fast baseline.
- Logistic Regression: for classification — estimates the probability of being a high performer.
- Random Forest: builds 100 decision trees and averages their predictions. “Wisdom of the crowd.”
- Gradient Boosting: builds trees one at a time, each fixing the previous one’s mistakes. Often the strongest on tabular data.
- SVM: finds the best boundary between classes. Good for small datasets, sensitive to scaling.
- KNN: for a new student, finds the 5 most similar students and averages their performance. Simple but scaling-sensitive.
Regression metrics:
- RMSE: “off by X points on average” (in GPA/score units).
- R²: variance explained. 1.0 is perfect, 0 = no better than guessing the mean.
Classification metrics:
- Accuracy: fraction of all predictions that were correct.
- Precision: of all predicted “high performers,” how many actually were?
- Recall: of all actual “high performers,” how many did we catch?
- F1: harmonic mean of precision and recall.

plt.show()Two TensorFlow neural networks
with modern regularization.
Same funnel architecture for both tasks (128→64→32→1) — only the output activation and loss function change.
What is a neural network? A stack of layers, each containing “neurons” (math units). Each neuron takes inputs, multiplies by weights (learned during training), adds a bias, and applies an activation function. “Deep” = many layers.
The architecture, explained:
Dense(128): 128 neurons, each connected to every neuron in the previous layer. First layer takes our features.Dense(64) → Dense(32) → Dense(1): the “funnel” — captures complex patterns then narrows to the answer.ReLU: if input is negative, output 0; if positive, output as-is. Lets the network learn non-linear patterns.
Regularization — preventing overfitting:
BatchNormalization: normalizes layer outputs during training. Stabilizes learning.Dropout(0.3): randomly disables 30% of neurons each step. Forces the network to learn redundant representations.
Training configuration:
Adam: adjusts learning rate automatically. The default choice for most projects.MSE loss(regression): penalizes large errors more than small ones.Binary crossentropy(classification): standard loss for yes/no problems (high vs. low performer).Epoch: one full pass through training data. We train for up to 200.Batch size (32): process 32 students at a time before updating weights.Validation split (0.2): 20% of training data held out to monitor overfitting.
Callbacks — automatic training controls:
EarlyStopping: if val loss doesn’t improve for 20 epochs, stop.restore_best_weights=Truerolls back to the best epoch.ReduceLROnPlateau: when val loss plateaus, halve the learning rate.
Regression vs classification — the only difference:
- Regression: final layer = LINEAR activation (outputs any number — the predicted GPA/score).
- Classification: final layer = SIGMOID activation (outputs 0–1 = probability of “high performer”). Threshold at 0.5.

How to read the results table:
- For regression: higher R² is better. Lower RMSE is better (in GPA/score units).
- For classification: higher accuracy, precision, recall, and F1 are all better.
The pattern you’ll see: On this student lifestyle dataset, Gradient Boosting and Random Forest typically match or beat the neural network. For structured/tabular data, tree-based ensembles are usually the better engineering choice.
Key lesson: The R² value tells you how much of the variance in academic performance is explained by sleep, screen time, and other features. If R² is 0.4, it means 40% of the variance is explained — the rest is due to factors not in the dataset (motivation, teaching quality, genetics, etc.).

actually tells us.
Six findings from running the full pipeline on the Student Sleep & Screen Time dataset.
// sleep ↔ GPA positive · screen time ↔ GPA negativeSleep hours positively correlate with academic performance
The scatter plot and heatmap typically show that students who sleep more tend to perform better academically.
Screen time negatively correlates with performance
More screen time (especially before bed) typically correlates with lower academic performance.
Correlation strength determines model R²
If sleep and screen time correlate with performance at ±0.3 to ±0.5, expect R² around 0.2–0.4.
Tree ensembles match or beat DL on lifestyle data
Gradient Boosting and Random Forest typically outperform the neural network on this structured dataset. Deep learning isn’t always the answer — for tabular data, tree-based ensembles win.
R² is moderate, not perfect — and that’s expected
Academic performance is influenced by many factors not in this dataset. A model that explains 30–50% of the variance is genuinely useful, not a failure.
The real value is feature importance, not prediction
For educators and parents, the most useful output isn’t the predicted GPA — it’s which features matter most. Random Forest’s feature importance can rank sleep, screen time, and study hours by their impact on performance.
Frequently Asked Questions
What is the Student Sleep & Screen Time dataset? +
The Student Sleep, Screen Time & Academic Performance dataset on Kaggle contains data about students’ lifestyle habits (sleep duration, sleep quality, screen time, study hours) and their academic performance (GPA or test scores).
Does sleep actually affect academic performance? +
Yes. The scatter plots and correlation heatmap typically show a positive correlation between sleep hours and academic performance, and a negative correlation between screen time and performance.
Is deep learning better than ML for this dataset? +
Not necessarily. On this structured lifestyle dataset, traditional ML models like Gradient Boosting typically match or outperform a 4-layer neural network. Deep learning tends to pull ahead on very large datasets or unstructured inputs.
Why is the R² not higher? +
Because academic performance is influenced by many factors not in this dataset. A model that explains 30-50% of the variance is genuinely useful, not a failure.
